3.2 Principle of operation

VEGAPULS 66 is a radar sensor in C-band (emitting frequencyapprox. 6 GHz) for continuous level measurement.

A special version of VEGAPULS 66 is available for each area ofapplication. The version with flange and horn antenna is particularly

suitable for measurement of liquids and solids under extremely difficultprocess conditions such as buildup, condensate and foam generationas well as vigorous product movement.

With the version without antenna horn, the antenna system is formedin conjunction with a measuring tube (surge or bypass tube). Thisversion is particularly suitable for measurement of solvents and liquidgases.

For pressures up to 160 bar (2320 psi) and temperatures up to 400 C(752 F) there are graphite seals and ceramic antenna conesavailable.

The antenna of the radar sensor emits short radar pulses with aduration of approx. 1 ns. These pulses are reflected by the productand received by the antenna as echoes. The running time of the radarpulses from emission to reception is proportional to the distance andhence to the level. The determined level is converted into anappropriate output signal and outputted as measured value.

Two-wire electronics 4 20 mA/HART for power supply andmeasured value transmission over the same cable.

The supply voltage range can differ depending on the instrumentversion.

The data for power supply are specified in chapter "Technical data".

The backlight of the indicating and adjustment module is powered bythe sensor. The prerequisite for this is a supply voltage at a certainlevel. The exact voltage specifications are stated in chapter "Technicaldata".

The optional heating requires its own operating voltage. You can finddetailed information in the supplementary instructions manual "Heatingfor indicating and adjustment module". This function is generally notavailable for approved instruments.

3.3 Operation

VEGAPULS 66 can be adjusted with different adjustment media:

l with indicating and adjustment modulel with the suitable VEGA DTM in conjunction with an adjustment

software according to the FDT/DTM standard, e.g. PACTware andPC

l with manufacturer-specific adjustment programs AMS or PDMl With a HART handheld

The entered parameters are generally saved in VEGAPULS 66,optionally also in the indicating and adjustment module or inPACTware.

4.1 General instructions

Select an installation position you can easily reach for mounting andconnecting as well as later retrofitting of an indicating and adjustmentmodule. The housing can be rotated by 330 without the use of anytools. You can also install the indicating and adjustment module in fourdifferent positions (each displaced by 90).

Use the recommended cables (see chapter "Connecting to powersupply") and tighten the cable gland.

You can give your instrument additional protection against moisturepenetration by leading the connection cable downward in front of thecable entry. Rain and condensation water can thus drain off. Thisapplies mainly to outdoor mounting as well as installation in areaswhere high humidity is expected (e.g. through cleaning processes) oron cooled or heated vessels.

Make sure that all parts of the instrument in contact with the measured

product, especially the sensor element, process seal and processfitting, are suitable for the existing process conditions such as processpressure, process temperature as well as the chemical properties ofthe medium.

You can find the specifications in chapter "Technical data" in the or onthe type label.

4.2 Mounting instructions

When mounting VEGAPULS 66, keep a distance of at least 500 mm

(19.69 in) to the vessel wall. If the sensor is installed in the center ofdished or round vessel tops, multiple echoes can arise. These can,however, be suppressed by an appropriate adjustment (see chapter"Setup").

If you cannot keep this distance you should carry out a false echostorage before setup. This applies mainly if buildup on the vessel wallis expected. In this case, we recommend repeating a false echostorage later with existing buildup.

Align the sensor in liquids as vertical as possible to the product surfaceto achieve optimum measurement.

Fig. 10: Alignment in liquids

The mounting location of the radar sensor should be a place where noother equipment or fixtures cross the path of the microwave signals.

Vessel installations such as, for example, ladders, limit switches,heating spirals, struts, etc. can cause false echoes that get super-imposed on the useful echo. Make sure when planning your measuringsite that the radar sensor has a "clear view" to the measured product.

In case of existing vessel installations, a false echo storage should becarried out during setup.

If large vessel installations such as struts or supports cause falseechoes, these can be attenuated through supplementary measures.Small, inclined sheet metal baffles above the installations scatter theradar signals and prevent direct interfering reflections.

Fig. 11: Cover smooth profiles with deflectors

If there are agitators in the vessel, a false echo storage should becarried out with the agitators in motion. This ensures that the interferingreflections from the agitators are saved with the blades in differentpositions.

Fig. 12: Agitators

Through the action of filling, stirring and other processes in the vessel,dense foams which considerably damp the emitted signals may formon the product surface.

If foams are causing measurement errors, the biggest possible radarantenna should be used.

As an alternative, sensors with guided microwave can be used. These

are unaffected by foam generation and are best suited for suchapplications.

By using a standpipe, the influence of vessel installations andturbulence can be excluded. Under these prerequisites, the meas-urement of products with low dielectric values (from DK value 1.6) ispossible.

Note:

Measurement in a standpipe is not recommended for very adhesiveproducts.

Surge or bypass tubes must extend all the way down to the requestedmin. level, as measurement is only possible within the tube.

Surge pipe

Make sure you provide the necessary upper vent hole in the surgepipe. The hole must be aligned so that it and the polarisation markingon the sensor flange are in the same plane (see illustration: "Pipeantenna system in a tank").

5.1 Preparing the connection

Always keep in mind the following safety instructions:l Connect only in the complete absence of line voltagel If overvoltage surges are expected, overvoltage arresters should

be installed

Tip:

We recommend using VEGA overvoltage arresters B63-48 andSB 62-36G.X.

In hazardous areas you should take note of the appropriate

regulations, conformity and type approval certificates of the sensorsand power supply units.

Power supply and current signal are carried on the same two-wirecable. The voltage supply range can differ depending on theinstrument version.

The data for power supply are specified in chapter "Technical data".

Provide a reliable separation between the supply circuit and the mainscircuits according to DIN VDE 0106 part 101. The VEGA power supply

units VEGATRENN 149A Ex, VEGASTAB 690 as well as allVEGAMETs meet this requirement.

Keep in mind the following additional influences on the operatingvoltage:

l Output voltage of the power supply unit can be lower undernominal load (with a sensor current of 20.5 mA or 22 mA in case offault message)

l Influence of additional instruments in the circuit (see load values inchapter "Technical data")

T

he instrument is connected with standard two-wire cable withoutscreen. If electromagnetic interference is expected which is above thetest values of EN 61326 for industrial areas, screened cable should beused.

Use cable withround cross-section. A cable outer diameter of 5 9 mm(0.2 0.35 in) ensures the seal effect of the cable gland. If you areusing cable with a different diameter or cross-section, exchange theseal or use a suitable cable gland.

We generally recommend the use of screened cable for HARTmultidrop mode.

On the instrument with cable entry NPT and plastic housing there isa metallic " threaded insert moulded into the plastic housing.

his would infl

uence the stability of the connection and thetightness of the housing.

If screened cable is necessary, connect the cable screen on both endsto ground potential. In the sensor, the screen must be connecteddirectly to the internal ground terminal. The ground terminal on theoutside of the housing must be connected to the potential equalisation(low impedance).

If potential equalisation currents are expected, the connection on theprocessing side must be made via a ceramic capacitor (e. g. 1 nF,

1500 V). The low frequency potential equalisation currents are thussuppressed, but the protective effect against high frequency interfer-ence signals remains.

Take note of the corresponding installation regulations for Exapplications. In particular, make sure that no potential equalisationcurrents flow over the cable screen. In case of grounding on both sidesthis can be achieved by the use of a capacitor or a separate potentialequalisation.

5.2 Connection procedure

Proceed as follows:

1 Unscrew the housing cover

2 If an indicating and adjustment module is installed, remove it byturning it slightly to the left.

6.4 Setup procedure

In HART-Multidrop mode (several sensors on one input) the addressmust be set before continuing with the parameter adjustment. You willfind a detailed description in the operating instructions manual"Indicating and adjustment module" or in the online help of PACTwareor DTM.

HART mode

Standard

Address 0

As VEGAPULS 66 is a distance measuring instrument, the distancefrom the sensor to the product surface is measured. To have the real

product level displayed, an allocation of the measured distance to thepercentage height must be made. To carry out this adjustment, thedistance is entered with full and empty vessel. If these values are notknown, an adjustment with the distance values, e.g. 10 % and 90 % isalso possible. Starting point for these distance specifications is alwaysthe seal surface of the thread or flange. With these settings, the reallevel is calculated. Furthermore the operating range of the sensor islimited from maximum to the required range.

The real product level during this adjustment is not important, becausethe min./max. adjustment is always carried out without changing the

product level. These settings can be made ahead of time without theinstrument having to be installed.

Caution:

If there is a separation of liquids with different dielectric values in thevessel, e.g. from condensation, VEGAPULS 66 can detect undercertain circumstances only the medium with the higher dielectric value.

Keep in mind that interfaces can cause faulty measurements.

If you want to measure the total height of both liquids reliably, pleasecontact our service department or use an instrument specially

designed for interface measurement.

In the main menu item "Basic adjustment", the individual submenuitems should be selected one after the other and provided with thecorrect parameter values.

Start your parameter adjustment with the following menu items of thebasic adjustment:

3 Save the settings with [OK]and move to "Medium selection" with[->].

Each product has different reflective properties. In addition, there arevarious interfering factors which have to be taken into account:agitated product surfaces and foam generation (with liquids); dustgeneration, material cones and echoes from the vessel wall (withsolids). To adapt the sensor to these different conditions, you shouldfirst select "Liquid" or "Solid".

Liquid

According to the conductivity and the dielectric value of liquids, thereflection properties can differ considerably. Therefore additionaloptions such as "Solvent", "Chem. mixture" and "Water based" areoffered below the menu item Liquid.

With solids, you can also choose between "Powder/Dust", "Granular/Pellets" or "Ballast/Pebbels".

Through this additional selection, the sensor is adapted perfectly to theproduct and measurement reliability, particularly in products with badreflective properties, is considerably increased.

Enter the requested parameter via the appropriate keys, save yoursettings and jump to the next menu item with the [->] key.

Apart from the medium, the vessel shape can also influence themeasurement. To adapt the sensor to these measuring conditions, thismenu item offers different options depending on whether liquid or solidis selected. With "Liquids" these are "Storage tank", "Stilling tube","Open vessel" or "Stirred vessel", with "Solid", "Silo" or "Bunker".

Vessel form

Storage tank


A linearization is necessary for all vessels in which the vessel volumedoes not increase linearly with the level - e. g. with a cylindrical orspherical tank - and the indication or output of the volume is required.Corresponding linearization curves are preprogrammed for thesevessels. They represent the correlation between the level percentageand vessel volume. By activating the appropriate curve, the volumepercentage of the vessel is displayed correctly. If the volume shouldnot be displayed in percent but e.g. in l or kg, a scaling can be also setin the menu item "Display".

Caution:

Note the following, if VEGAPULS 66 is used as part of an overfillprotection system according to WHG:

If a linearisation curve is selected, the measuring signal is no longer

compulsorily linear proportional to the level. This must be taken intoconsideration by the user, particularly when adjusting the switchingpoint on the level switch.

In this menu item you can enter an unambiguous designation for thesensor, e.g. the measurement loop name or the tank or productdesignation. In digital systems and in the documentation of largerplants, a singular designation should be entered for exact identificationof individual measuring sites.

Sensor-TAG

Sensor

With this menu item, the Basic adjustment is finished and you can nowjump to the main menu with the [ESC] key.

High sockets or vessel installations, such as e. g. struts or agitators aswell as buildup and weld joints on the vessel walls cause interferingreflections which can impair the measurement. A false echo storagedetects and marks these false echoes, so that they are no longer takeninto account for the level measurement. A false echo memory shouldbe created with low level so that all potential interfering reflections willbe detected.

Proceed as follows:1 Move from the measured value display to the main menu by

pushing [OK].

2 Select the menu item "Service" with [->] and confirm with [OK].Now the menu item "False signal suppression" is displayed.

3 Confirm "False signal suppression - Change now" with [OK] andselect in the below menu "Create new". Enter the actual distancefrom the sensor to the product surface. All false signals in this areaare detected by the sensor and saved after confirming with [OK].

Note:Check the distance to the product surface, because if an incorrect (toolarge) value is entered, the existing level will be saved as false signal.The filling level would then no longer be detectable in this area.

The menu item "Extended setting" offers the possibility to optimiseVEGAPULS 66 for applications in which the level changes veryquickly. For this reason, select the function "Quick level change > 1 m/min.".

Extended setting

quick level change > 1 m/min.

Note:

Since with the function "Quick level change > 1 m/min." the generationof an average value of the signal processing is considerably reduced ,false reflections by agitators or vessel installations can causemeasured value fluctuations. A false echo memory is thus recom-

mended.

This function enables reading out parameter adjustment data as wellas writing parameter adjustment data into the sensor via the indicatingand adjustment module. A description of the function is available in theoperating instructions manual "Indicating and adjustment module".

6.6 Saving the parameter adjustment data

It is recommended noting the adjusted data, e.g. in this operatinginstructions manual and archive them afterwards. They are henceavailable for multiple use or service purposes.

If VEGAPULS 66 is equipped with an indicating and adjustmentmodule, the most important data can be read out of the sensor intoindicating and adjustment module. The procedure is described in theoperating instructions manual "Indicating and adjustment module" inthe menu item "Copy sensor data". The data remain there permanentlyeven if the sensor power supply fails.

If it is necessary to exchange the sensor, the indicating and adjustmentmodule is inserted into the replacement instrument and the data arewritten into the sensor under the menu item "Copy sensor data".

Influence of the superimposed gas and pressure to the accuracy

The spreading speed of the radar impulses in gas or vapour above the product is reduced by highpressures. This effect depends on the superimposed gas or vapour and increases with lowtemperatures. The following chart shows the deviation caused by some typical gases or vapours .The stated values refer to the distance. Positive values mean that the measured distance is toohigh, negative values that the measured distance is too small.
