Quick start

1. In this menu item you can select the application. You can choose between level and interface measurement.

2. In the menu item "Medium - Dielectric constant" you can dene the type of medium (medium).

3. Carry out the adjustment in the menu items "Min. adjustment" and "Max. adjustment".

4. A "Linearization" is recommended for all vessels in which the vessel volume does not increase linearly with the level - e.g. in a horizontal cylindrical or spherical tank. Activate the appropriate curve.

5. A "False signal suppression" detects, marks and saves the false signals so that they are no longer taken into account for level measurement. We generally recommend a false signal suppression.

Parameterization example

3.2 Principle of operation

The VEGAFLEX 81 is a level sensor with cable or rod probe for continuous level or interface measurement, suitable for applications in liquids.

Functional principle level measurement

44217-EN-130910

VEGAFLEX 81 • Probus PA

High frequency microwave pulses are guided along a steel cable or a rod. Upon reaching the product surface, the microwave pulses are reected. The running time is evaluated by the instrument and outputted as level.

3 Product description

Fig. 5: Level measurement

1 Sensorreferenceplane(sealsurfaceoftheprocesstting)

d Distance to the interface h Height - Level

Probe end tracking

To increase sensitivity, the probe is equipped with probe end tracking. In products with a low dielectric constant, this function is very helpful. This is the case, for example, in plastic granules, packing chips or in vessels with uidized products.

Between a dielectric constant of 1.5 and 3, the function switches on, if required. As soon as the level echo can no longer be detected, probe end tracking is automatically activated. The measurement is continued with the last calculated dielectric constant.

The accuracy thus depends on the stability of the dielectric constant. If you measure a medium with a dielectric constant below 1.5, probe

end tracking is always active. In this case, you have to enter the dielectric constant of the medium. A stable dielectric constant is very important here.

Functional principle - interface measurement

High frequency microwave impulses are guided along a steel cable or rod. Upon reaching the product surface, a part of the microwave impulses is reected. The other part passes through the upper product and is reected by the interface. The running times to the two product layers are processed by the instrument.

Bypass tube

Spacer

The combination of a bypass tube and a VEGAFLEX 81 enables con-

tinuous level measurement outside the vessel. The bypass consists of a standpipe which is mounted as a communicating container on the side of the vessel via two process ttings. This kind of mounting ensures that the level in the standpipe and the level in the vessel are the same.

The length and the process ttings can be congured individually. No dierent connection versions available.

You can nd further information in the operating instructions manual "Bypass tube VEGAPASS 81".

If you mount the VEGAFLEX 81 in a bypass tube or standpipe, you have to avoid contact to the bypass tube by using a spacer at the probe end.

You can nd additional information in the operating instructions manual "Centering".

4.1 General instructions

On instruments with process tting thread, the hexagon must be tightened with a suitable screwdriver. Wrench size see chapter "Dimen- sions".

Warning:

The housing must not be used to screw the instrument in! Applying tightening force can damage internal parts of the housing.

Protection against moisture

Protective caps

Suitability for the process conditions

Protect your instrument further through the following measures against moisture penetration:

Use the recommended cable (see chapter "Connecting to power

•

supply") Tighten the cable gland

•

Loop the connection cable downward in front of the cable gland

•

This applies particularly to:

Outdoor mounting

•

Installations in areas where high humidity is expected (e.g. through

•

cleaning processes) Installations on cooled or heated vessels

•

In the case of instrument housings with self-sealing NPT threads, it is not possible to have the cable entries screwed in at the factory. The openings for the cable glands are therefore covered with red protective caps as transport protection.

Prior to setup you have to replace these protective caps with approved cable glands or close the openings with suitable blind plugs.

The suitable cable glands and blind plugs come with the instrument.

Make sure that all parts of the instrument exposed to the process are suitable for the existing process conditions.

These are mainly:

Active measuring component

•

Process tting

•

Process seal

•

Process conditions are particularly:

Process pressure

•

Process temperature

•

Chemical properties of the medium

•

Abrasion and mechanical inuences

4.2 Mounting instructions

Mount VEGAFLEX 81 in such a way that the distance to vessel installations or to the vessel wall is at least 300 mm (12 in). In non-metallic

4 Mounting

vessels, the distance to the vessel wall should be at least 500 mm (19.7 in).

During operation, the probe must not touch any installations or the vessel wall. If necessary, fasten the probe end.

In vessels with conical bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is then possible nearly down to the lowest point of the bottom. Keep in mind that measurement all the way down to the tip of the probe may not be possible. The exact value of the min. distance (lower dead band) is stated in chapter "Technical data".

Fig. 7: Vessel with conical bottom

Type of vessel

Plastic vessel/Glass vessel

The guided microwave principle requires a metal surface on the process tting. Therefore use in plastic vessels etc. an instrument version with ange (from DN 50) or place a metal sheet (ø > 200 mm/8 in) beneath the process tting when screwing it in.

Make sure that the plate has direct contact with the process tting. When installing rod or cable probes in vessels without metal walls,

e.g. in plastic vessels, the measured value can be inuenced by strong electromagnetic elds (emitted interference according to EN 61326: class A). In this case, use a probe with coaxial version.

Socket

If possible, avoid sockets. Mount the sensor ush with the vessel top. If this is not possible, use short sockets with small diameter.

Higher sockets or sockets with a bigger diameter can generally be used. They can, however, increase the upper blocking distance (dead band). Check if this is relevant for your measurement.

In such cases, always carry out a false signal suppression after installation. You can nd further information under "Setup procedure".

Measuring range

Before beginning the welding work, remove the electronics module from the sensor. By doing this, you avoid damage to the electronics through inductive coupling.

Do not mount the instruments in or above the lling stream. Make sure that you detect the product surface, not the inowing product.

Fig.11:Mountingofthesensorwithinowingmedium

The reference plane for the measuring range of the sensors is the

sealing surface of the thread or ange. Keep in mind that a min. distance must be maintained below the refer-

ence plane and possibly also at the end of the probe - measurement in these areas is not possible (dead band). The length of the cable can be used all the way to the end only when measuring conductive

products. These blocking distances for dierent mediums are listed in chapter "Technical data". Keep in mind for the adjustment that the default setting for the measuring range refers to water.

Pressure

Standpipes or bypass tubes

The process tting must be sealed if there is gauge or low pressure in

the vessel. Before use, check if the seal material is resistant against the measured product and the process temperature.

The max. permissible pressure is specied in chapter "Technical data" or on the type label of the sensor.

Standpipes or bypass tubes are normally metal tubes with a diameter of 30 … 200 mm (1.18 … 7.87 in). In measurement technology, such a tube corresponds to a coax probe. It does not matter if the standpipe is perforated or slotted for better mixing. Lateral inlets in bypass tubes also do not inuence the measurement.

For bypass tubes, select the probe length such that the blocking distance (dead band) of the probe is above or below the lateral lling openings. You can thus measure the complete range of the medium in the bypass tube. When designing the bypass tube, keep the blocking distance of the probe in mind and select the length above the upper lateral lling opening accordingly.

Microwaves can penetrate many plastics. For process technical reasons, plastic standpipes are problematic. If durability is no problem, then we recommend the use of metal standpipes.

When the VEGAFLEX 81 is used in standpipes or bypass tubes, contact with the tube wall must be avoided. We recommend for this purpose a cable probe with centering weight.

With rod probes, a spacer is generally not required. However, if there is a risk of the rod probe being pressed against the tube wall by inowing medium, you should mount a spacer at the probe end to avoid contact with the tube wall. In the case of cable probes, the cable can be strained.

Keep in mind that buildup can form on the spacers. Strong buildup can inuence the measurement.

Note:

Measurement in a standpipe is not recommended for extremely adhesive products.

Instructions for the measurement:

The 100 % point should not be above the upper tube connection

•

to the vessel The 0 % point should not be below the lower tube connection to

•

the vessel A false signal suppression with installed sensor is generally rec-

•

ommended to achieve maximum possible accuracy.

If there is a risk of the cable probe touching the vessel wall during operation due to product movements or agitators, etc., the measuring probe should be securely xed.

In the gravity weight there is an internal thread (M8), e.g. for an eyebolt (optional) - (article no. 2.1512).

Make sure that the probe cable is not completely taut. Avoid tensile loads on the cable.

Avoid undened vessel connections, i.e. the connection must be either grounded reliably or isolated reliably. Any undened change of this requirement can lead to measurement errors.

In case of dicult installation conditions, the probe can be also mounted laterally. For this purpose, adapt the rod with rod extensions or bow-shaped segments.

Let the probe length determine automatically by the instrument to compensate the resulting running time changes.

The determine probe length can deviate from the actual probe length when using bow-shaped segments.

If installations such as struts, ladders, etc. exist on the vessel wall, then the probe should have a distance to the vessel wall of at least 300 mm (11.81 in).

You can nd further information in the supplementary instructions of the rod extension.

Safety instructions

5 Connecting to power supply

5.1 Preparing the connection

Always keep in mind the following safety instructions:

Connect only in the complete absence of line voltage

•

If overvoltage surges are expected, overvoltage arresters should

•

be installed

Voltage supply

Connection cable

Cable gland ½ NPT

Cable screening and grounding

The voltage supply is provided by a Probus DP /PA segment coupler.

The voltage supply range can dier depending on the instrument version. You can nd the data for voltage supply in chapter "Technical data".

Connection is made with screened cable according to the Probus specication. Power supply and digital bus signal are carried over the same two-wire connection cable.

Use cable with round cross-section. A cable outer diameter of 5 … 9 mm (0.2 … 0.35 in) ensures the seal eect of the cable gland. If you are using cable with a dierent diameter or cross-section, exchange the seal or use a suitable cable gland.

Please make sure that your installation is carried out according to the Probus specication. In particular, make sure that the termination of the bus is done with appropriate terminating resistors.

You can nd detailed information of the cable specication, installation and topology in the "ProbusPA-UserandInstallationGuide- line" on www.probus.com.

With plastic housing, the NPT cable gland or the Conduit steel tube

must be screwed without grease into the threaded insert. Max. torque for all housings see chapter "Technical data".

Make sure that the cable screen and grounding are carried out according to Fieldbus specication. We recommend to connect the cable screen to ground potential on both ends.

With systems with potential equalisation, connect the cable screen directly to ground potential at the power supply unit, in the connection box and at the sensor. The screen in the sensor must be connected directly to the internal ground terminal. The ground terminal outside on the housing must be connected to the potential equalisation (low impedance).

Connection technology

5.2 Connecting

The voltage supply and signal output are connected via the spring-

loaded terminals in the housing. The connection to the display and adjustment module or to the inter-

face adapter is carried out via contact pins in the housing.

5.8 Set instrument address

An address must be assigned to each Probus PA instrument. The approved addresses are between 0 and 126. Each address must only be assigned once in the Probus PA network. The sensor is only recognized by the control system if the address is set correctly.

When the instrument is shipped, address 126 is adjusted. This address can be used for function test of the instrument and for connection to a Probus PA network. Then address must be changed to integrate additional instruments.

The address setting is carried out either via:

The address selection switch in the electronics compartment of

•

the instrument (address setting via hardware) The display and adjustment module (address setting via software)

•

PACTware/DTM (address setting via software)

•

Hardware addressing

The hardware addressing is eective if an address <126 is adjusted

with the address selection switches on the instrument. Hence the software addressing is no longer eective, the adjusted hardware address is valid.

A linearization is necessary for all vessels in which the vessel volume does not increase linearly with the level - e.g. a horizontal cylindrical or spherical tank, when the indication or output of the volume is required. Corresponding linearization curves are preprogrammed for these vessels. They represent the correlation between the level percentage and vessel volume.

The linearization applies for the measured value indication and the current output. By activating the suitable curve, the percentage vessel volume is displayed correctly.

False signal suppression

High sockets and internal vessel installations cause interfering reections and can inuence the measurement.

A false signal suppression detects, marks and saves these false signals so that they are no longer taken into account for the level and interface measurement. We generally recommend carrying out a false signal suppression to achieve the best possible accuracy. This should be done with the lowest possible level so that all potential interfering reections can be detected.

Enter the actual distance from the sensor to the product surface. All interfering signals in this section are detected by the sensor and

stored. The instrument carries out an automatic false signal suppression

as soon as the probe is uncovered. The false signal suppression is always updated.

Proceed as follows:

Enter the actual distance from the sensor to the product surface.

All interfering signals in this section are detected by the sensor and stored.

Note:

Check the distance to the product surface, because if an incorrect (too large) value is entered, the existing level will be saved as a false echo. The lling level would then no longer be detectable in this area.

Failure: Due to a malfunction in the instrument, a failure message is outputted.

This status message is always active. It cannot be deactivated by the user.

Function check: The instrument is in operation, the measured value is temporarily invalid (for example during simulation).

This status message is inactive by default. It can be activated by the user via PACTware/DTM or EDD.

Outofspecication: The measured value is unstable because the instrument specication is exceeded (e.g. electronics temperature).

This status message is inactive by default. It can be activated by the user via PACTware/DTM or EDD.

Maintenance: Due to external inuences, the instrument function is limited. The measurement is aected, but the measured value is

9.4 Rectify faults

The operator of the system is responsible for taking suitable meas-

ures to rectify faults.

The rst measures are:

Evaluation of fault messages, for example via the display and

•

adjustment module Checking the output signal

•

Treatment of measurement errors

•

Further comprehensive diagnostics options oer a PC with the software PACTware and the suitable DTM. In many cases, the reasons can be determined in this way and faults can be rectied.

Treatment of measurement errors

The below tables show typical examples for application-relevant

measurement errors. There are two measurement errors:

Constant level

•

Filling

•

Emptying

•

The images in column "Error pattern" show the real level with a broken line and the level displayed by the sensor as a continuous line.

The propagation speed of the radar impulses in gas or vapour above the medium is reduced by high pressure. This eect depends on the superimposed gas or vapour and is especially large at low temperatures.

The following table shows the resulting deviation for some typical gases and vapours. The specied values refer to the distance. Positive values mean that the measured distance is too large, negative values that the measured distance is too small.

Approvals

Instruments with approvals can have dierent technical data depending on the version. For that reason the associated approval documents of these instruments must be carefully noted.

They are part of the delivery or can be downloaded under www.vega.com and "VEGA Tools" as well as under "Downloads" and "Approvals".

11.2 CommunicationProbusPA

Instrumentmasterle

The instrument master le (GSD) contains the characteristic data of the Probus PA instrument.

The prerequisites for maintaining the protection rating are a suitable cable as well as correct mounting.

VEGAFLEX 81 • Probus PA

44217-EN-130910

11 Supplement

These data are, e.g. the permissible transmission rates as well as information on diagnostics values and the format of the measured value outputted by the PA instrument.

A bitmap le is also provided for the Probus network planning tool. This le is installed automatically when the GSD le is integrated. The bitmap le is used for symbolic indication of the PA instrument in the conguration tool.

ID number

Each Probus instrument gets an unambiguous ident number (ID number) from the Probus user organisation (PNO). This ID number is also included in the name of the GSD le. Optionally to this manufacturer-specic GSD le, PNO provides also a general so-called prole-specic GSD le. If the general GSD le is used, the sensor must be set to the prole-specic ident number via the DTM software. By default, the sensor operates with the manufacturer-specic ID number. When using the instruments on a segment coupler SK-2 or SK-3, no special GSD les are required.

Module of the PA sensors

For the cyclic data trac, VEGAFLEX 81 provides the following modules:

AI FB1 (OUT)

•

– Out value of the AI FB1 after scaling

AI FB2 (OUT)

•

– Out value of the AI FB2 after scaling

AI FB3 (OUT)

– This module must be used if a value in the data telegram of the cyclical data trac should not

be used (e.g. replacement of temperature and Additional Cyclic Value)

A maximum of three modules can be active. By means of the conguration software of the Probus master you can determine the conguration of the cyclical data telegram with these modules. The procedure depends on the respective conguration software.

Note:

The modules are available in two versions:
