ON THE COVER
Paperless calibration systems made with
the combination of documenting calibrators
and calibration software improves quality
and cuts costs. The business benefits are
significant for companies that use software-
based calibration systems when compared
with manual, paper-based systems.
Whi le using a manual, paper-based
system requires little or no investment
in new technology or IT systems, it is
extremely labour-intensive and means that
historical trend analysis of calibration results
becomes very difficult. In addition, accessing
calibration data quickly is not easy. Paper
systems are time-consuming, they soak
up lots of company resources and manual
(typing) errors are commonplace. Dual effort
and the re-keying of calibration data into
multiple databases become significant costs
to the business.
The business benefits of a paperless
calibration system are significant. The whole
calibration process - from initial recording
of calibration data through to historical
trend analysis - will take less time, while
mistakes and manual errors will be virtually
eliminated. In turn, this means that operators,
engineers and management will have more
confidence in the data, particularly when
it comes to plant audits. In addition, this
greater confidence in calibration data leads
to a better understanding and analysis of
business performance and KPIs (particularly
if the calibration software is integrated with
other business IT systems such as a CMMS)
leading to improved processes, increased
efficiencies and reduced plant downtime.

There are many technologies available today for the automated measurement of the level of a material in a vessel. All the available techniques work when applied correctly in the appropriate situation.

CHOICES IN AUTOMATED LEVEL DETECTIONGlenn Johnson, Editor
PART 1
FEBRUARY 2013 - WHAT'S NEW IN PROCESS TECHNOLOGY 7www.ProcessOnline.com.au
CHOICES IN AUTOMATED LEVEL DETECTION There are many level measuring
situations in which virtually any measuring technology will work, but there are also many cases
where some technologies will work while most others will not. Generally speaking, it is a case of the more difficult the process environment or material, the more costly and complex the level technology.
This article is an overview of those com-mon technologies and techniques that can be considered ‘automated’ instrumentation. Manual level measurement gauges are not covered.
Head versus heightLevel measurement techniques can be cat-egorised into two broad categories. One is ‘head measurement’, which is based on the force of the process material pushing down on a measuring device, and ‘height meas-urement’, which is based on measuring the distance to the upper surface of the material.
Head measurementFor head measurement, there are two basic categories: one is the measurement of the weight of the process vessel or tank and the other is the measurement of the pressure applied by the material in the tank. Of these, measuring the weight of the vessel (usually performed with load cells under the tank supports) can give an accurate measure of how full the tank is, given that the density of the material is known - and it works for both solid and liquid measurement. The only risks of error here are electrical interference with the load cells, and vibration - the vessel needs to be shielded from vibrations, which may be transferred to the load cells, leading to spurious measurements.
Measuring the pressure exerted by the contents of the tank is generally only suitable for liquids, but there are various methods of doing so, depending on the measuring conditions and material.
Height measurementHeight measurement means measuring the distance of the top surface of the material (liquid or solid) from either the top (most common) or bottom of the vessel. Various forms of contact-based and non-contact methods are used, and some permit the detection of multiple levels simultaneously (liquid interface level measurement) where two materials of different density are present, one floating on the other. All methods have
their pros and cons, and the correct method must be chosen based on the conditions of the process and the properties of the process material.
Point level versus continuousSometimes we want to know the fill level of a vessel at all levels, to measure the quan-tity of material available. In other cases we are only interested if the level falls below a certain point, perhaps to trigger refilling, or if it exceeds a certain point, to prevent overflow, or to stop a filling process. The first is called continuous level measurement and requires a method that is constantly seeking or following the top surface level of the material. The second is called point level measurement and uses instruments or sensors located at appropriate heights in the vessel that are triggered when the material level passes that point - in other words there is a change of the conditions surrounding the sensor.
ChallengesDepending on the liquid or solid to be measured, the design of the vessel and the conditions of the process, various challenges may be encountered.
The design of the vessel must be taken into account, not only for its shape (in some cases the geometry of the vessel affects the level calculation), but also for internal structural features such as seams, supports and ladders, which may obstruct certain types of measurement.
In some cases, the material may be so corrosive or flammable, or the vessel may be so hot or cold that no form of instrument can enter the vessel. In these cases, nuclear level measurement may be the only solution.
SolidsFor solids, the nature of the solid and the way it behaves in the vessel affect the measure-ment. Obviously, using head measurement by measuring the weight of the vessel eliminates all issues of the material properties, but this is not always practical, such as in the case of very large silos. Surface height measure-ment of solids presents various challenges:
• Surface dynamics - The filling and emp-tying of the vessel results in a sloping top surface (the material has an ‘angle of repose’), that makes it difficult to de-termine the ‘average’ top level (Figure 1). Also, particle size has an impact on the

•Dust and noise - Dust filling the spaceabovethematerial,aswellassoundandelectromagnetic noise, are common insolidsvessels and can have detrimentaleffectsonvarioustypesofmeasurementmethods.
•Material build-up - Some instrumentsare particularly sensitive to materialbuild-up that can interfere with radioor electronic measurements or clog upmoving mechanisms.
LiquidsWhile liquids usually provide a nice flatsurface for surface measurement, theremay be other challenges surrounding theparticular liquid that will affect what typeof level measurement is used.
• Corrosion-Someliquidsarehighlycor-rosivesocontactmethodsofmeasurementmay not be appropriate, since the liquidwill damage the instrument. Corrosivevapours may also be present above theliquid, so non-contact instruments needto be protected.

Methods of interfacingWiththeexceptionofvesselweighingmethodsandnucleonicmeasurement,mostmethodsofmeasurement involvesomeformofcon-nectionwith the insideof thevessel, if notwith the material itself.
Tank bridlesOnemoretraditionalwayofattachinginstru-ments inthecaseof liquidmeasurement isthe same way that visual level indicators
have traditionally been configured. A bridle(also known as an isolating column or by-pass pipe) is a vertical pipe connected tothe side of the vessel, typically with twoconnections to the side of the vessel (highand low), orwith onehighon the side andoneatthebottom(Figure2).Becauseundermostcircumstancesthefluidinsidethebridlewillriseandfallequallywiththelevelofthefluidinthevessel,thebridlecanbeusedasthe location to apply the level instruments,althoughinmostcasesinstrumentsareplacedintheirownbypasspipeornozzleattachedtothebridle.Therearemanyadvantagesinusing a bridle:

usedwithtankbridles,inthecaseofsolidsmeasurement (and also many liquid meas-urementapplications)aninstrumentmaybemounteddirectlythroughanopeninginthetank. In the case of liquid head measure-ment, this may involve the direct connec-tion of one or more pressure instrumentsdirectly to the side or bottom of the tank.In this case, valves may be interposed formaintenance purposes.
Inthecaseofcontinuousheightmeasure-ment for both solids and liquids, this willinvolve inserting the instrument though ahole in the top of the vessel. In this case,the risk of the detrimental effects listedabove needs to be taken into account ineach case.
Point level instrumentsThe simplest application of level sensingis for detection of levels at fixed pointsfor simple applications such as preventingoverfill or run-dry, and to start and stopfillingoperations.Allthepoint level instru-mentsdescribedbelowinvolvesomeelementwhich protrudes into the process materialand comes into contact with it.
Float switchesFloat switches use a float and magneticswitching action to switch when the floatrises or falls with a liquid level. They areonly suitable for liquids, and usually onlyfor overfill detection, and come in verticalandhorizontal orientations andcanbe topor side mounted. Their main advantageis their simplicity, but their disadvantageis the use of moving parts that can wearout, and the risk of seizing if they are notoperated frequently. For this reason, they
arenotsuitable forcritical leveldetection,especially for hazardous liquids.

Capacitance point level switchesCapacitance type limit switches are staticlevel sensors, use a sensing rod insulatedfrom a ground sleeve. A capacitance isformed by the sense rod and earth exten-sion, or the metal wall of a vessel. Whenno material is present, the capacitance isdirectly proportional to the probe dimen-sionsanddielectricconstantofair( 0≈1).When material is present, the capacitancegets multiplied by dielectric constant ofthe material. This variation in capacitanceis then translated into switching output bythe device.
The main advantage is that there areno moving parts, but the material beingdetected must have a dielectric constantdifferentfromair,andliquidsmustbenon-conductive.Theycanalsobedetrimentallyaffected by static charges in silos.
Conductive point level switchesConductive limit switches work by insert-ing a rod into the vessel and applying analternatingvoltage. In the simplest design,whenanelectricallyconductiveliquidcon-tactstheprobe itmakesacircuitbetweenthe probe and the vessel wall. When thevesselisnon-conductive,aversionwithan

integral ground probe can be used. Somedesignshavemultipleprobeswithdifferentlengthssothatifsuspendedverticallytheycan detect multiple levels.
Using alternating voltage prevents cor-rosion of the probe rods and electrolyticdestruction of the product. They are onlysuitable for use with conductive liquids.
Themainlimitationsofconductivelevelswitches are that contamination of theprobes can prevent detection, and theymay not be reliable if the conductivity ofthe liquid varies.

PROFINET IRT GATEWAYSHMS Industrial Networks has released a series of Anybus X-gateways that enable communication be-
tween several industrial networks and Profinet IRT. The X-gateways can connect Profibus and CANopen
to Profinet IRT with fibre-optics, and ControlNet, EtherNet/IP and DeviceNet to Profinet IRT with copper
cabling. They help plant owners and machine builders to migrate to Profinet without making changes
to their existing machinery.
The X-gateways copy I/O data between any industrial network and Profinet IRT. Gateway settings
regarding, for example, I/O sizes are configured in a Windows-based terminal interface which means
no programming is necessary.
The Profinet interface of the X-gateway works as an I/O device on the Profinet IRT network and supports
up to 220 B of I/O for both input and output data. The gateway’s baud rate is 100 Mbps (full duplex)
and uses two RJ45 connectors (copper) or two SC-RJ connectors (fibre) allowing installations in line
or ring topology. The integrated 2-port IRT switch eliminates the need for expensive external switches.

OSCILLATION ANALYSISExpertune’s PlantTriage software has been en-
hanced with tools to extend its oscillation analysis
features. The software automates the engineering
analysis, completing a Fourier transform and
identifying key periods of oscillation. The software
then filters the information so only the most likely
sources of the problem will be identified.
The oscillation analysis tools are fully inte-
grated into PlantTriage’s web browser interface,
and a preconfigured Problem-Solver report for
oscillation analysis is included. The report can
be viewed online, emailed, exported to Excel,
or even scheduled for email delivery whenever
PlantTriage finds a significant issue. No program-
ming or SQL skills are required.
The cycle detection and analysis tools are
included with all PlantTriage systems, version
11.01 and higher. Existing PlantTriage users
receive the features at no charge, as part of
their software maintenance agreement.

MOBILE BULK BAG FILLING SYSTEMThe latest mobile bulk bag filling system from Flexicon features an
integral metal detector/separator and a tilt-down conveyor/feeder
for dust-free filling at multiple locations.
The system detects metal in the free-fall stream of material en-
tering the filler and then ejects it through a chute that discharges
into a removable drum at the rear of the unit.
The filler is also equipped with fill head height adjustment to
accommodate all popular bag sizes; an inflatable cuff to seal the
bag inlet spout; a blower to remove bag creases prior to filling;
load cells for filling by weight; a vent port for dust-free air displace-
ment during filling; pneumatically retractable bag hooks; and an
automated vibratory densification/deaeration system to maximise
capacity and stabilise the bag for storage or shipment.
The first bulk bag filler to receive USDA acceptance, it is con-
structed of 316 stainless steel, finished to sanitary standards and
configured with full-length forklifting tubes allowing it to be moved
throughout the plant.
The conveyor’s inlet hopper includes an air displacement vent with cartridge filter that is equipped
with a reverse pulse cleaning system that dislodges accumulated dust with short bursts of com-
pressed air, returning the dust to the hopper on a timed cycle, maintaining operating efficiency.
The programmable controls are housed in a stainless steel NEMA 4X enclosure with touch
screen that graphically displays filling functions.

PLANT MOBILITY SOLUTIONHoneywell has released Experion Mobile Access, a mobility applica-
tion that provides secure remote access to Honeywell’s Experion
Process Knowledge System (PKS) through mobile computing
devices. Experion Mobile Access enables field operators to view
and respond to live information from Experion PKS while they are
on rounds or inspecting the plant.
To meet plant and field operators’ need for fast and easy ac-
cess to plant data, the company has developed Experion Mobile
Access, which works securely with the Experion PKS architecture
and the company’s OneWireless Network. This software applica-
tion provides seamless field data access for plants with complex
processes and expansive footprints that rely on a large mobile
operator staff for proper operations, and to support the availability
of process equipment.
It is designed to help field operation teams find and avert process
conditions that could affect production output. Recent cases stud-
ies have shown that an average-sized refinery or chemical plant
can see up to $1 million per year in savings, a 15% improvement
in mean time between failure of assets and a 10% reduction in
maintenance costs.
Experion Mobile Access leverages Experion Distributed System
Architecture (DSA), including Experion eServer technology to deliver
data to field operators throughout the facility. Its web-based user
interface has been optimised for small mobile devices, such as
industrial handhelds commonly employed by workers during their field
rounds, but also other devices such as smartphones and tablets.

Though used like a print mark sensor, the Sick ML20
sensor requires no optical marking on the package,
instead detecting a taught-in design pattern. In future,
the label on beverage bottles or chocolate bars and
packaged chips can be in the right spot even without
a registration marking.
The ML20 uses a novel method for detecting
contrast patterns. In the process, the sensor is
taught a pattern sequence, eg, the graphic images
or lettering, which is then detected at a scanning
rate of up to 7 m/s, resulting in the output of a
switching signal. Even if the labels have a complex
design or the machine is operating at high speed,
the ML20 detects nearly any pattern with accuracy
and stability.
MARKLESS LABEL SENSOR
PRODUCTSINSTRUMENTATION & SENSORS
The metal housing of the sensor provides a high
level of ruggedness, and it is easy both to integrate
in machines and to commission. The sensor works
reliably even if the image patterns are intricate or
the process varies.
When changing label or foil reels, the sensor
avoids unnecessary cutting loss and waste, since
pattern recognition is active right away, enabling
use of the material starting immediately after the
beginning of the reel. In some packaging pro-
cesses, for instance when labelling bottles, there
are additional savings of the additional material
previously used exclusively for the print mark. The
markless technology allows savings up to 5% of
material per label.

THERMAL MASS FLOW METERS
Sierra Instruments has introduced the QuadraTherm 640i/780i
thermal mass flow meter series. With its sensor design
advancements, coupled with a proprietary iTherm algorithm, the
780i inline version achieves gas mass flow rate measurement
accuracy of ±0.5% of reading above 50% of the full scale (air).
Traditional thermal sensors have two sensors - one tem-
perature sensor and one velocity sensor, each in a separate
probe. QuadraTherm introduces four sensors - three precision
platinum temperature sensors and one no-drift DrySense
mass velocity sensor, which uses a proprietary manufacturing
process to improve accuracy and long-term stability.
The QuadraTherm sensor isolates forced convection
(the critical variable for measuring gas mass flow rate) by
calculating and then eliminating unwanted heat-transfer
components like sensor stem conduction, one of the major
causes of false flow readings. The result is a fundamentally
different gas mass flow rate calculation using all pertinent
variables for a precise, stable and accurate thermal mass
flow measurement.
The product is available in two models: the 640i inser-
tion and 780i inline. The range has a no-drift sensor and a
multivariable output for mass flow, temperature and pressure
(optional). It measures all inert and all non-condensing clean
gases as well as flammable gases (methane, propane, hy-

SENSORS FOR HYGIENIC ENVIRONMENTS
The Banner Engineering QM26 and QMH26 photoelectric
sensors are designed specifically for the food and beverage
and pharmaceutical industries. The sensors’ design con-
siders Hazard Analysis and Critical Control Point (HACCP)
principles for hygienic manufacturing processes, and they
are designed to work in areas where the sensors may come
in contact with food or materials. They are suitable for
harsh washdown environments with high pressure, extreme
temperatures and chemicals.
The QM26 is housed in a non-toxic 316L stainless steel
housing and can survive high-pressure washdowns and
temperature cycling, ranging from -30 to 60°C. The sensor
is ECOLAB certified for inexhaustible sensor life in chemi-
cally cleaned environments and is intended for splash zone
areas. The QM26 also features easy side-mounting for quick
set-up and installation.
The QMH26 has all the advantages of the QM26; however,
it is designed with minimal grooves and crevices, leaving
no room for bacteria to hide and multiply. It is self-draining
for clean-in-place (CIP) applications. The sensor’s hygienic
mounting shape reduces contamination risk, making it a
suitable sensor to place in contact zones.

RH AND TEMPERATURE TRANSMITTERS
Maintaining reliable RH measurements in harsh or corrosive environments is notoriously difficult as the conditions
themselves degrade the sensors and equipment, often in short tim periods. To provide a solution to this
problem, Michell Instruments has released the DT722 RH and temperature transmitter.
To best meet specific application needs, the DT722 series is available in digital (DT722) and
analog (DT722-X18) models. The digital electronic platform version gives high-performance
measurement and RH accuracy and delivers reliable, consistent and accurate results even
over changing ambient conditions.
The DT722-X18 is an analog through-path measurement device with high mechanical
toughness. Field adjustment is quick and easy, making it a good choice for use in all
types of aftermarket service and it is already in service in the nuclear industry.
The transmitters have been designed for use in severe industrial environments. They offer
a strong, stainless steel housing providing protection against rough handling or accidental
damage, IP65 (NEMA 4) ingress protection, and a probe that can withstand temperatures
up to 150°C.
The transmitters are for duct mounting in the most suitable place for the application. They have
high chemical resistance for longer use in contaminated areas and are available with a selection of filter
materials to afford best protection to the sensors based on specific environmental conditions.

MECHATRONIC FLOW SENSORS
ifm efector’s SBT series mechatronic flow
sensors can be used for flow ranges
from 0.3 to 25 L/min at pressure
ranges of up to 15 bar.
The sensors function on the prin-
ciple of the spring-supported piston:
the piston, located in the valve seat
in the housing, is lifted by the flowing
medium against the spring resistance.
The mechatronic measuring principle
enables response times of less than 10 ms.
At the same time, the spring resistance forces the piston
to return to its original position with decreasing flow. This
ensures position-independent installation of the flow sensor,
preventing backflow.
Due to the temperature decoupling of the transducer from
the electronics, some versions of the sensor are suitable
for media in high-temperature applications of up to 180°C.
The sensors can be set intuitively and provide an analog
output signal.

Honeywell SmartLine pressure transmitters are designed to make it easier to support field devices and promote
plant reliability with their efficiency-enhancing features, such as a graphic display capable of showing process
data in graphical formats and communicating messages from the control room. SmartLine transmitters also feature
modular components to simplify field repairs and reduce inventory required to make those repairs.
The display supports graphical process data in easy-to-read trend lines and bar graphs while also providing
a platform for operator messages, comprehensive diagnostic warnings and loop status for maintenance. These
capabilities are part of the transmitter’s Smart Connection Suite, and allow control room operators to send
messages to the display to make it easier and faster for field operators to identify the correct transmitter
and determine required maintenance tasks. When integrated with Honeywell’s Experion Process Knowledge
System (PKS), the transmitter can also display its maintenance mode - telling field operators if the control loop
is in a safe state to perform maintenance. Installation is made easier with the smart display - three buttons
at the top of the transmitter are used with the graphic display to completely configure the transmitter with no
external handheld devices required.
The modular design streamlines maintenance by allowing replacement of individual transmitter components instead of the
entire unit, even in hazardous locations. This design reduces plant life cycle costs by providing purchasing flexibility, lowering
inventory costs and reducing maintenance and repair work.
Other safety and efficiency features include enhanced security alerts and wiring polarity insensitivity.

AERATION ANALYSER
Endress+Hauser’s Liquiline CDC80 optimises aeration
times in the biological stage of wastewater treatment.
This is the stage that is energy-intensive as most oxy-
gen blowers are operated in a time-based manner or
using only a simple form of oxygen control.
The analyser allows the aeration process to be run
according to the wastewater ammonium load, which
is far more efficient. It monitors ammonium load and
controls the oxygen blowers so the aeration process
only runs until the ammonium value has reached a
predefined lower set limit.
The product also determines the oxygen setpoint
value, which is adjusted dynamically depending on
the ammonium load, so the plant can be attuned
to different load situations. This leads to optimised
operating times for nitrification and denitrification, and
reduced energy consumption. Phosphate precipitant
dosing can also be controlled by the device, ensur-
ing efficient phosphate conversion and saving on
precipitant and costs.
The product can connect to existing instrumentation
and be easily integrated into existing process control
systems. Additionally, if the company’s Memosens
technology is used, calibration values and measured
values can be digitally transferred to the transmitter
without interference. A remote access function is
available for even faster and easier maintenance - a
safe VPN channel allows monitoring and change of
parameters.

The Turck LI inductive linear position sensor has an enhanced
electronics architecture that increases the effective output rate
of the sensor from 1 to 5 kHz. In conjunction with the short signal run time
(130 µs) and the highly resolved SSi output, the inductive linear position sensors
can achieve the performance of potentiometers but without their disadvantages.
Unlike potentiometers, the LI sensors offer permanent protection to IP67,
provide non-contact measuring and are wear-free. The magnetic field im-
mune sensors are suitable for measuring axes with high-speed controls
such as those used in injection moulding machines. Other application areas
include axis measurement in packaging machines, presses or machine tools.
With the high speed and precision of the sensor (system resolution of
1 µm), machine builders can keep the position error in motor control ap-
plications to a minimum. As with all inductive linear position sensors, the
high-speed variant has very short blind zones and can tolerate up to a
4 mm offset of the positioning element (perpendicular to the measuring
axis). As well as the high-speed variant with an SSI interface and 16-bit
resolution, the analog variant of the sensor will also be offered in the future
with the higher output rate of 5 kHz. The analog sensor has a 0-10 V or
4-20 mA output. All LI sensors continue to be available in 10 measuring
lengths from 100 to 1000 mm. An 8-pole M12 connector is used for the
connection.

The Hach Sonatax sc with sc200 controller is designed to help
with sludge extraction and the management of recirculation, and
provide warnings of potential solids washouts or process upsets by
continuously measuring the sludge blanket level. Its digitised probe
eliminates interference and features a quick LED system check. If
connected with the sc1000 controller, graphical display of sludge
profile is also available.
The Sonatax sc offers reduced maintenance with an innovative
wiper design, and a built-in position sensor can be used to resume
measurements after skimmer passes. The same sensor can also
compensate for angle when the probe is not mounted exactly vertically.
High accuracy is achieved by automatically scanning a range of
frequencies to find the ideal settings for the solids concentration for
the application. Built-in software disregards signals reflected from
tank structures such as pipes and rods. Automatic temperature
compensation ensures the ultrasonic measurement is unaffected by
seasonal changes in water temperature, making seasonal calibra-
tion unnecessary.
A visual performance LED indicator light on the probe provides
quick glance assurance of proper performance. Troubleshooting,
particularly in applications with multiple sludge blanket level probes
connected to one controller, is quick and easy.

Yokogawa has enhanced the ADMAG AXR two-wire magnetic flowmeter. This enhanced flowmeter has
been certified for use in safety integrity level 2 (SIL2) applications and it supports the latest HART 7
protocol, eliminating the need for convertors to connect with HART-compliant control systems.
HART 7 also supports and automatic alarms when the device’s settings are modified or a problem
is detected by self-diagnostics.
The ADMAG AXR flowmeter uses a dual-frequency excitation method, with low-frequency
excitation that ensures stable measurement of flow rates and high-frequency excitation that
delivers high noise resistance, thus realising stable measurement in a wide range of fluid con-
ditions. This high-performance two-wire flowmeter can be used in both monitoring and control
applications. Its installation and maintenance costs are significantly lower because two-wire
magnetic flowmeters do not require a dedicated power supply unit and use only a single pair
of cables. Their low power consumption also reduces running costs. In addition, explosion-
proof types suitable for installation in hazardous areas are now available for the entire range,
covering bore diameters from 25 to 200 mm.

DIFFERENTIAL PRESSURE INSTRUMENTS
Emerson Process Management has introduced a significant number of
enhancements to its Rosemount 3051 pressure instruments. The first of the
enhanced capabilities is a standard reference accuracy of ±0.04% of span down
to a 10:1 turndown. This improvement drives the total performance in typical
operating conditions to ±0.12% of span.
The Power Advisory Diagnostics feature is a predictive diagnostic tool that
allows users to identify electrical loop issues, at the instrument or anywhere
in the loop, before they cause a loss of measurement. With simple three-step
activation and guided troubleshooting, users of all experience levels can easily
implement this diagnostic to help prevent costly outages and minimise the
time spent diagnosing and resolving the root cause of a measurement issue.
The company has added a local operator interface (LOI) to the product,
designed with straightforward menus and both internal and external con-
figuration buttons for on-the-spot commissioning - even in hazardous areas.
The enhanced instrument also offers selectable HART revision capability
(HART5 and HART7) to deliver the latest features to those that are ready to
take advantage of the latest HART revision while ensuring seamless integra-
tion with any installed host, asset management system or configuration tool.
The product now also offers SIL2 certification, allowing users to avoid extra
shutdowns for safety testing. Emerson also provides full documentation for
efficient SIS compliance. Users can add Power Advisory Diagnostics to SIL2-
certified transmitters to improve safety throughout their entire electrical loop.

INFRARED TEMPERATURE SENSORThe PyroMini infrared pyrometer from Calex Electronics has a miniature sensing head measuring 18 x 45 mm, making it suitable for mounting in tight spaces. The high ambient sensing head is capable of withstanding temperatures of up to 180°C without water or air cooling and has a measuring range of -20 to 1000°C.
Manufactured from 316 stainless steel and sealed to IP65, the PyroMini sensing head is suitable for the food and pharmaceutical industry, as well as automotive manufacture and many other industrial measurement and control applications.
The non-contact temperature sensing head utilises a low-noise interconnecting cable (available in lengths from 1 to 30 m), making it resistant to interference from external electromagnetic fields such as those encountered with dynamic moving machines like robot arms.
The backlit touch-screen interface provides a large, bright display of the measured temperature in digital format as well as in a graphical view that shows the history of the measured temperature, date and time. In alarm conditions, the display changes colour to provide an immediate and obvious alarm indication.
When in data logging mode, the PyroMini records the temperature related data to a MicroSD card. With a 2 GB MicroSD card, the user can store 28.4 million time and date stamped readings, which provides almost one year’s worth of data at the fastest possible sample rate of one per second.
Output options include an analog 4-20 mA temperature-related retransmission, as well as RS485 Modbus and two alarm relay outputs.

INTEGRATED SERVO DRIVE MOTORThe Allen-Bradley Kinetix 6000M integrated drive motor combines servo drive and motor technologies in a compact, on-machine package, using the MP-Series food-grade servo motor and Kinetix 6000 multi-axis servo drive technologies.
Moving servo drives out of the control enclosure and onto the machine delivers significant space savings, while reducing cabling. The integrated drive-motor system is claimed to reduce panel space required by up to
60% for a typical 8-axis system. Additionally, the number of cables exiting the control enclosure is reduced by as much as
75% because a hybrid/network cable daisy chain re-places the individual power and feedback cables.
The drive-motor is designed to integrate seam-lessly with the Kinetix 6000 and Kinetix 6200 multi-axis servo-drive systems and features an integrated drive-motor power interface module that mounts directly to a standard Kinetix 6000 power rail. The mounting flange and shaft di-mensions of the integrated drive-motor units are identical to the MP-Series motors of the same frame size, minimising the mechanical changes needed to use integrated drive-motor technology.
The system is suitable for applications such as packaging, converting, print and web machines. It
meets the needs of food and beverage packaging and handling applications by offering features geared
for the industry, including enhanced sealing techniques, corrosion-resistant materials and coating appropriate for food environments.
The drive motor is available in three different frame sizes, offering optional
holding breaks and SIL2/PLd safe torque-off functionality.

BECOME AN ENGINEERING ENTREPRENEUR TODAY
Almost on a daily basis, you read about Australian manufacturing (and even mining) businesses shutting down.
After the hammering of the recent ‘Great Recession’, companies are rapidly reduc-ing tangible assets - buildings, machines and, inevitably, people such as high-cost engineering staff. And we know that there is a massive amount of outsourcing going on - meaning jobs go elsewhere, often overseas. This is all happening today and will eventually impact on you in some form.
The days of expecting a job for 30 to 40 years, say, from one company are rapidly diminishing as competition intensifies. I clearly remember starting out in the diamond mining business as a junior engineer with thousands of other highly skilled engineering professionals working for this one company. It had been around for over a hundred years and we all believed it would be around for many more years. Today, it is a poor shadow of itself with only a tiny number of engineers and technicians. An unbelievable situation when one considers how dynamic and profitable it was only 20 years ago.
We thus need to approach the problem of employment from a different angle and create engineering jobs ourselves. And employ others. Engineering professionals have the innate technical prowess to make things. Add in creativity to the mix and an understanding of what the market wants and you could have a winning product or service within months. Admittedly, you may work long hours and be exposed to some stress along the way.
But the winners are individuals which we refer to as engineer-entrepreneurs and companies that come up with new products and services which the global community wants. And keep coming up with new prod-ucts or improvements to existing products. Otherwise they also die.
We thus need the engineer-entrepreneur to conceptualise and design new products and services. A product doesn’t have to be something totally unique or new; a slight improvement on an existing product, service or process can also be a winner. This ap-
plies to you whether you are working for another company or for yourself. Seek out opportunities to innovate and create new products and services. In this way you can extend the life of your company and your career.
It should be noted that as an engineer-entrepreneur, there is a chasm between successfully operating a startup company and a small business. The much vaunted business schools tend to gloss over the differences and treat both as the same, but they are totally different. One key difference is that a startup company often has a brilliant product which has incredible possibilities, but no actual market (at present) - so the startup has the additional challenge of get-ting the product to market.
Engineering professionals also have to be ferociously self-sufficient, self-sustaining and lifelong learners responsible for staying in business. They also have to be prepared to learn from their customers in optimising their creations so that they are economi-cally viable. Often we hear things from our customers that we don’t want to hear. Inevitably, engineer-entrepeneurs must be prepared to have a high threshold of toler-ance to repeated failure and the ability to persist to success.
Above all - you have to believe in yourself.As George Lois points out: Creativity can
solve almost any problem. The creative act, the defeat of habit by originality, overcomes everything.
