TM710e

The Strategic Impact of Accurate Moisture Control In the quest for optimal process efficiency and product quality, the implementation of accurate, real-time, on-line moisture measurement and control is of strategic importance to the Primary Process.

Today’s making machines achieve ever higher outputs, with the result that controlling blend moisture in order to ensure fastest cigarette making speeds and target in-pack moisture content, has become a critical endeavour.

Process Challenges With its wide moisture range and multiple measurement points, the process demands an instrument that requires the minimum of adjustment, that can be applied in any location.

The Need for Measurement

Accurate Moisture Control is required to optimize process capability in leaf and primary processing...

NDC & the Tobacco Industry

NDC Infrared Engineering has over 40 years experience in the design and manufacture of on-line instruments specifically for the tobacco industry.

Our engineering, development and manufacturing teams benefit from in-depth knowledge of the natural physical and chemical attributes of tobacco, the measurement and control requirements in the process, as well as the industry’s analytical methods used in quality assurance systems. Their ability to create accurate, stable measurements that can be trusted for process control is unmatched.

In addition, our commercial team has forged strong relationships with key players in the industry - both producers and equipment manufacturers - and it is this combined technical and commercial knowledge that has enabled us to develop the TM710e - the 8th generation instrument, dedicated to the on-line measurement needs in primary and GLT processing.

Our direct operations in Europe, China, Japan, Brazil and the USA, and fully trained distributors in over 60 countries, ensure that the industry can rely on NDC, not just for instrument performance, but for first-class local support, too.

The instrument also needs to be able to handle process variables (such as product height variation), environmental variables (such as ambient lighting effects, relative humidity or tempera-ture) and tobacco product variables (such as naturally varying characteristics of the leaf blend).

In summary, the instrument must reliably ensure that changes in the moisture measurement output are due only to changes in the tobacco moisture.

The NDC TM710e Tobacco Gauge delivers measurable improvement in dynamic performance. The use of an increased number of wavelengths in the TM710e’s innovative Dynamic Scatter Correction Algorithm further reduces the influences of variations between blends and between grades. This in turn reduces demonstrably the calibration requirement.

TM710e’s state-of-the-art measurement capability, supported by intuitive oper-ator and supervisory interfaces, enables the user to obtain the fastest return on investment.

The TM710e Tobacco Gauge

TM710e, the Ethernet-Enabled NIr On-Line Gauge, combines the proven TM710 light engine with high-speed digital processing and Ethernet connectivity. This powerful combination produces the highly accurate, robust real-time measure-ments essential for use in closed-loop control, yet offers full flexibility and simplicity of installation and operation.

Designed specifically for process control and using industry-standard Ethernet communication hardware such as hubs, cables, repeaters and routers, the modular TM710e system offers low installation costs, low maintenance overhead and the lowest cost of ownership.

Key components of the TM710e Gauging System are the Gauge itself, the Operator Workstation (OWS) and the Human Machine Interface (HMI), offering choice of configuration for a wide variety of system structures.

The OWS enables local interaction with an individual gauge, while the HMI provides supervisory access to up to 16 networked TM710e gauges. Both units feature high definition multi-lingual colour touch screen displays. A multi-way Hub with advanced switching technology, enables convenient networked con-figurations. Digital inputs and out-puts and scaleable analogue outputs are available to provide additional connectivity via the HMI or the versatile UserPort communications terminal.

Precision Optics, High Speed Digital Processing and Ethernet Connectivity deliver a winning combination of measurement performance and stability...

The Science behind the TM710e The TM710e works on the principal

that tobacco constituents, such as

water, sugars or nicotine, absorb NIr

(Near Infra-red) Light at specific

wavelengths. When tobacco is

exposed to this NIr light, it absorbs

an amount which is related to the

level of constituent present, and

reflects the rest.

The TM710e generates and emits

these specific wavelengths by using

rotating optical filters to transform

the energy from a QH lamp into

sequential pulses of NIr light at the

desired wavelengths.

It then captures the reflected NIr

light, using a special multi-segment

mirror to focus it onto a light-

sensitive detector. Before leaving the

gauge, a beam-splitter diverts a

portion of the beam to the secondary

detector, to form the reference signal

against which the reflected light will

be compared.

The TM710e processes the detector

signals through its “DSC” algorithm

to generate a linear output propor-

tional to the detected amount of

measured constituent. The TM710e’s

patented optics reject ambient light,

rH & temperature influences to

generate a highly stable measure-

ment, irrespective of product height

fluctuation.

InstallationThe TM710e should be attached to a sturdy support and suspended over

the conveyor or process line at a distance from the mean product height

to the TM710e measurement window of 250mm, ±100mm. The optics

are designed to accommodate product height fluctuations of ±100mm,

without affecting the measurement. The Operator Workstation should be

installed close to the gauge in an accessible position where the display is

clearly visible.

Ambient ConditionsThe tobacco processing environment can be dusty and steamy. NDC

supplies an Air Purge Window Shield, which is connected to a clean air

supply to create a positive air pressure in front of the measurement win-

dow, to prevent dust or steam deposits. Ambient lighting will not affect

the TM710e. The TM710e is sealed to IP65 standards and can operate

in ambient temperatures between 0 and 50OC without cooling. IP67 and

ATEX certified housings are available for aggressive or hazardous areas.

The OWS is sealed to IP65 and is suitable for ambient temperatures

between 0 and 50OC

CablingAs standard, NDC provides a 10m power cable and 10 m connecting

cable to the Operator Workstation. For more details on cable lengths,

consult the “Series 710e Gauge Overview” and also the “Series 710e

Configuration and Connectivity Guide”.

ConnectivityThe gauge measurement output is available in digital and analogue

forms. The response time (measurement integration period) is user adjust-

able from 0.2 to 1000 seconds, typically set between 0.5 and 10 seconds,

to provide a measurement output to the PLC or process control system.

CalibrationThe TM710e is delivered with NDC’s “SpeedCal” pre-calibration ready

for use for the specified measurement(s) and range(s) shown in the

Applications Chart. On installation it is simply adjusted to agree with the

local reference method. The GaugeToolsxL software provided simplifies

this process by enabling comparison of TM710e values (collected on-line

using the SAMPLE function on the OWS) with laboratory results.
