1 Product description

Level measurement on high temperature processes or on mediums with high temperature was formerly very difficult or even impossible. If in addition the measurement should be made under high pressure, up to now there was no measuring system available. Apart from a non-contact measurement with good measuring accuracy.

In distillation and stripper columns, up to now levels (e.g. of sump, plate and head products) could generally only be measured by pressure sensors or differential pressure measurements. The installation required for such pressure measuring systems (pressure lines, pressure transmitters…) is considerable and expensive, often amounting to several times the value of the sensor itself. Due to missing of suitable alternatives, instrumentation departments have not only to arrange with this fact but also with high maintenance costs (cleaning of measuring pipes, errors by condensation, build-up on the diaphragm…) and often had to accept inadequate accuracy (temperature errors, density fluctuations, installation faults …).

The requirements of the petrochemical industry for a non-contact level sensor are the following:

• independent of temperature and pressure

• process temperature up to 350°C

• process pressure up to 64␣ bar

• high resistance wetted parts for universal use

• accuracy 0,1␣ %

• rugged metal housing

• Ex-approved (available in EEx d and EEx ia)

• Loop-powered as well as digitally connectable

Product description

Sensors which would not have been possible without the new results in the material and production technology. An especially developed ceramics is used as coupling material. This ceramic is chemically and thermically very high resistant.

The sensor materials in contact with the process are all highly resistant. This refers not so much to the flange material of high-alloy stainless steel (1.4571 or superior), as to the specially developed ceramic (Al2O3) and its gland. The ceramic rod receives from the high frequency module the radar signals and the cone-shaped end works as emitter and receiver. The seal between stainless steel flange and ceramic rod is made with a Tantalum seal ring.

1.1 Function

Radio detecting and ranging: Radar.

VEGAPULS radar sensors are used for noncontact and continuous distance measurement. The measured distance corresponds to a filling height and is provided as level.

Measuring principle:

emission – reflection – receipt

Smallest 5,8␣ GHz radar signals are emitted from the antenna of the radar sensor as short pulses. The radar impulses reflected by the sensor environment and the product are received by the antenna as radar echoes. The running period of the radar impulses from emission to receipt is proportional to the distance and hence to the level.

This initial position defines the development aims for a high-temperature radar level measuring system of VEGAPULS 56 series. A special new development of high-temperature radar sensors for level measurement in temperatures up to 350°C and pressures up to 64␣ bar.

4 VEGAPULS 56V

Product description

Meas. distance

emission - reflection - receipt

The radar impulses are emitted by the antenna system as impulse packets with a pulse duration of 1 ns and pulse breaks of 278 ns; this corresponds to a pulse package frequency of 3,6␣ MHz. In the impulse breaks the antenna system operates as receiver. Signal running periods of less than one millionth of a second must be processed and the echo pictures must be evaluated in a fraction of a second.

1 ns

Hence it is possible for the VEGAPULS 56 radar sensors to process the slow-motion pictures of the sensor environment precisely and in detail in cycles of 0,5 up to 1 second without using very time consuming frequency analysis (e.g. FMCW) necessary for other radar principles.

Virtually all products can be measured

Radar signals physically react similar to visible light. According to the quantum theory they penetrate empty space. Hence they are not bound such as e.g. sound to a conductive product (air) and spread like with light velocity. The radar signals react to two electrical primary quantities:

- the electrical conductivity of a substance.

- the dielectric constant of a substance.

All products which are electrically conductive reflect radar signals very well. Even only slightly conductive products ensure a sufficient signal reflection for a reliable measurement.

All products with a dielectric constant ε more than 2,0 reflect radar impulses sufficiently (note: air has a dielectric constant figure ε

of 1).

278 ns

Pulse sequence

VEGAPULS radar sensors can reach this in a special procedure of time transformation which spreads more than 3,6 million echo pictures per second in a slow motion picture, then freezes and processes them.

Product description

The signal reflection increases with the conductivity or with the dielectric constant of the medium. Hence virtually all mediums can be measured.

Due to standard flanges from DN 50 to DN 250, ANSI 2“ to ANSI 10“ the sensor antenna systems are adapted to the various measured products and process environments. High-quality materials withstand also extremely chemical and physical conditions. The sensors deliver reliable, precise and longterm stable, reproducible analogue or digital level signals.

Continuous and reliable

Unaffected by temperature, pressure and atmosphere type, VEGAPULS radar sensors detect quickly and precise levels of different mediums.

1.3 Adjustment

Each measuring distance is different, hence each radar sensor must be given some basic information on the application and the environment.

The adjustment and parameter adjustment of the radar sensors are carried out with

- the PC

- the detachable adjustment module MINICOM

- the signal conditioning instrument VEGAMET

Adjustment with PC

The set-up and adjustment of the radar sensors is generally made on the PC with the adjustment program VVO (VEGA Visual Operating) under Windows

The program leads quickly through the adjustment and parameter adjustment via pictures, graphics and process visualisations.

1.4 Antennas

The antenna is the eye of the radar sensor. Various antenna configurations are available for different applications and process conditions.

Horn antenna

Horn antennas focus the radar signals very well. Manufactured of 1.4571 (stst) or Hastelloy C22 they are very rugged and physically as well as chemically resistant. Horn antennas are used for measurement in closed or open vessels.

DN 150

DN 50

Pipe antenna

Pipe antennas on surge or bypass pipes only form a complete antenna system in conjunction with a measuring pipe which can also be bent. Pipe antennas are best suited for products with extreme product movements or products with low dielectric constant.

The antenna can be with or without horn. It characterizes by very good antenna gain. A very good antenna reliability can be achieved even in case of products with very bad reflection features.

The measuring pipe means a conductor for radar signals. The running period of the radar signals changes in the pipe and depends on the pipe diameter. The pipe inner diameter must be programmed in the electronics so that the running period can be compensated.

2 T ypes and versions

VEGAPULS 56 sensors are a new developed generation of very compact high temperature radar sensors. For the first time it is now possible to carry out a non-contact level measurement under high temperatures and pressures. They open the advantages of a radar level measurement for applications where the special advantages of radar were formerly not applicable due to the extreme process conditions.

VEGAPULS 56 radar sensors dominate the two-wire technology perfectly. They are the first radar sensors transmitting the supply voltage and the output signal via one twowire line. As output or measuring signal they operate with an analogue 4␣ …␣ 20␣ mA-output signal or with a digital output signal. This operating instruction describes the sensors with digital output signal.

2.2 Configuration of measuring systems

A measuring system consists of a sensor and a processing unit. The processing unit (the signal conditioning instrument VEGAMET or the processing system VEGALOG) processes the level proportional digital measuring signal in a number of processing routines and provides then the levels as individual current, voltage or switching signals.

On the signal conditioning instrument VEGAMET 515V two sensors can be connected via one two-wire line. On the processing system VEGALOG 571 up to 255 sensors can be connected; 15 sensors (loop powered) on one two-wire line.

Beside the output of the levels in percent, cubic metres or other physical units, as current, voltage or switching signal (relay or transistor) the levels can also be processed via combined processing algorithms. Scaling, linearisation, calculation of linearisation curves, differential generation, addition or tendency processing are fixed implemented in the processing systems VEGALOG and VEGAMET as processing routines and easily available via menu choice.

On the following pages you will see different instrument configurations, called measuring systems:

• 2 sensors on one two-wire line;

• 2 sensors in Ex-area on one two-wire line;

(page 14)

• 15 sensors on one two-wire line;

• 5 sensors in Ex-area on one two-wire line;

(page 16)

(page 13)

(page 15)

Ex-area

The sensors with classification EEx␣ ia require for operation in Ex-areas the Ex-separator VEGATRENN 548V␣ Ex, providing intrinsically safe Ex-circuits to the sensors. The sensors with classification EEx␣ d␣ ia are provided with a pressure tight encapsulated connection box. This converts a non-intrinsically safe supply circuit into an intrinsically safe circuit.

Up to 15 sensors in groups with five sensors each per two-wire line can be connected to Ex-separator VEGATRENN 548V␣ Ex

17)

Note!

In Ex-systems earthing on both sides is not allowed due to the potential difference.

Note:

Sensor lines should be looped in screened cables. It is suitable (except Ex-systems) to earth the cable screens on both ends. Therefore it must be noted that no earth compensation currents flow via the screens. In case of earthing on both sides earth compensation currents are avoided by connecting the cable screen on one earth side (e.g. in the switching cabinet) via a capacitor (e.g. 0,1␣ µF; 250␣ V) to the earth potential.

Sensor lines leading to the same input card or separator card can be looped together in a screened multiple wire cable. Sensor lines leading to other separator cards must be looped in separated screened cables.

3.3 Approvals

When using radar sensors in Ex and StExareas or on ships the instruments must be suitable and approved for these explosion zones and applications. The suitability is checked by the approval authorities and is certified in approval documents.

VEGAPULS 56 radar sensors are approved for Ex zone 1 and zone 0, this is ensured by two Ex-concepts.

Sensors with classification EEx␣ ia must be operated for use in Ex-areas via the separators VEGATRENN 548V␣ Ex. They provide intrinsically safe (ia) circuits.

Sensors with classification EEx␣ d␣ ia can be directly connected to the signal conditioning instrument or the processing system for use in Ex-areas as the connection box of the EEx␣ d-sensors is pressure tight encapsulated and the ignition proof barrier is located in the pressure tight encapsulated connection box. The resistance of the signal lines must not exceed 15␣ Ω per wire.

Please note the attached approval documents (yellow binder) when you want to use the sensor in Ex-area.

4.1 General installation instructions

Measuring range

The reference plane for the measuring range of the sensors is the flange face. The measuring range is 0␣ …␣ 20␣ m. For measurements in surge or bypass pipes (pipe antenna) the max. measuring distance is reduced (see "Technical data - Meas. range“).

Mounting and installation

Please note that for measurements where the measured product reaches the sensor flange, build-up on the antenna is possible which can cause measurement errors. Therefore the min. distance of the antenna to the medium should be 5 cm.

False reflections

Flat obstructions and struts cause large false reflections. They reflect the signal with high amplitude.

Round profile interfering surfaces have a diffuse reflection of the radar signals and

If flat obstructions in the range of the radar signals cannot be avoided, it is recommended to reflect the interfering signals with a deflector. Due to this scattering the interfering signals will be low in amplitude and diffuse so that they can be filtered out by the sensor.

Mounting and installation

Emission cone and false reflections

The radar signal is focused by the antenna system. The signal leaves the antenna in conical form similar to the beam pattern of a spotlight. This emission cone angle depends on the antenna used.

Any object in this emission cone causes a reflection of the radar signal. Within the first few metres of the emission cone mechanical obstructions cause strong false reflections. In a distance of 6 m the false signal of a pipe has 9-times more amplitude than at a distance of 18 m.

Heat isolation

In case of process temperatures of more than 200°C an isolation on the rear of the flange is necessary to separate the radiation heat from the sensor electronics.

4.2 Measurement of liquids

Sensor on DIN-socket piece

Most of the time the mounting of radar sensors is made on short DIN-socket pieces. The instrument flange is the reference plane of the measuring range. The antenna should always protrude out of the flange pipe.

Reference plane

Mounting on short DIN-socket piece

When the DIN-socket piece is longer, note that the horn antenna must protrude at least 10 mm out of the socket.

The best would be to include the sensor isolation into the vessel isolation and isolate it up to approx. the first pipe segment.

Sensor directly on the vessel top

Dependent on the construction of the vessel (sensor weight), flat mounting directly on the vessel top would be a favourable solution. The top side of the vessel is the reference plane.

Mounting on dished end vessel

Do not mount the transmitter in the centre of the dished end of the tank or close to the wall of the vessel, but approx. 1/2 vessel radius from the middle or from the outer wall of the vessel.

Dished tank ends can act as paraboloidal reflectors. If the radar sensor is placed in the "focus“ of a parabolic tank end, the sensor receives amplified false echoes. The radar sensor must be mounted outside the "focus“ hence parabolic amplified echoes are avoided.

4.3 Measurement in a standpipe (surge or bypass pipe)

General instructions

Pipe antennas are an option in vessels which are mechanically complex or where the product surface is very turbulent.

By focusing of the radar signals within the measuring pipe, also products with small dielectric constant figures (ε be reliably measured.

The surge pipes which are open at the bottom must extend over the full measuring range (i.e. down to 0% level).

Suitable will be a deflector at the tube end. The medium is therefore reliably detected in the range of the min. level. This is mainly important for mediums with a dielectric constant figure of less than 5.

When using a ball valve in a surge pipe, it is possible to carry out maintenance and service work without opening the vessel (e.g. with liquid gas or toxic products).

The radar sensor with a DN!50 flange is only in conjunction with a measuring pipe a functional system.

The measuring pipe must be smooth inside (average roughness Rz!≤!30). Use as measuring pipe a stainless steel pipe without joint. Extend the measuring pipe to the required length with welding neck flanges or with connecting sleeves. Note that no shoulders are caused in the pipe during welding. Fasten the pipe and the flange before welding in alinement with the inner sides.

Do not just weld through the pipe wall. Roughnesses or joints must be removed carefully as otherwise strong false echoes and build-up will be caused.

Min. product level to be measured (0!%)

With the deflector on the measuring pipe end, the radar signals are reflected from the vessel bottom. This ensures that in nearly empty vessel and products with low dielectric constants, the medium is detected and not the vessel bottom. In products with low dielectric constant figures, the product is penetrated by radiation and the vessel bottom delivers at low level considerably clearer radar echoes than the product surface.

Due to the deflector, the useful signal remains and hence the measured value can be clearly detected in nearly empty vessel and the 0!%-level is reliably detected.

4.4 False echoes

The installation place of the radar sensor must be chosen such that no struts or inflowing material cross the radar signals. The following examples and instructions show frequent measuring problems and how they can be avoided.

Shoulders

Vessel forms with flat shoulders pointing to the antenna can influence the measurement due to their hard false echoes. Deflectors above these flat shoulders diffuse the false echoes and ensure a reliable measurement.

Correct Wrong

Screen

Flat shoulders

Inlets, e.g. for material mixing with flat surface pointing to the radar sensor, should be covered by a screen. False echoes are hence gated out.

Vessel installations

Vessel installations, such as e.g. a ladder often cause false echoes. Note when planning a measurement loop that the radar signals reach the product without problems.

Correct Wrong

Ladder

Vessel installations

Ladder

Struts

Struts such as vessel installations can cause strong false echoes which can overlay the useful echo. Small screens avoid a direct false echo reflection. The false echoes are diffused and filtered out by the measuring electronics as "echo noise“.

Strong product movements

Heavy turbulences in the vessel, e.g. by strong stirrers or strong chemical reactions influence the measurement. A surge or bypass pipe (figure) of sufficient size allows, provided that the product causes no buildup in the pipe, always a reliable measurement even with strong turbulences in the vessel.

Correct Wrong

100 %

75 %

Heavy turbulences

Products which can cause slight build-up can be measured by using a measuring pipe with 100 mm nominal width and more. In a measuring pipe of this size, slight build-up is not a problem.

Build-up

If the radar sensor is mounted too close to the vessel wall, build-up on the vessel walls causes false echoes. Position the radar sensor in a sufficient distance to the vessel wall. Also note chapter "4.1 General installation instructions“.

Wrong directing to the product surface

A directing of the sensor which does not point to the product surface will cause weak measuring signals. If possible, direct the sensor axis vertically to the product surface, to reach optimum measuring results.

Round or parabolic tank tops act for the radar signals like a parabolic mirror. If the radar sensor is placed to the focus of such a parabolic tank top, the sensor receives amplified false echoes. The optimum mounting is generally in the range of the half vessel radius from the centre.

Mounting and installation

Standpipe (pipe antenna) without ventilation hole

Pipe antenna systems must be provided with a breathing hole on the upper edge of the surge pipe. A missing hole will cause wrong measurements.

Correct Wrong

Pipe antenna: The surge pipe open to the bottom must have a ventilation hole on top

Wrong polarisation direction on the standpipe

When measuring in a surge pipe, especially if there are holes or slots in the pipe for mixing, it is important that the radar sensor is directed to the row of holes.

The two rows of holes of the surge pipe displaced by 180° must be in line with the polarisation direction of the radar signals. The polarisation direction is in line with the hole. The sensor is precisely directed by means of the hole in the intermediate flange.

Hole

The polarisation direction is in line with the hole. The sensor must be directed with the hole to the rows of holes

Sensor too close to the vessel wall

If the radar sensor is mounted too close to the vessel wall, strong interfering signals can be caused. Build-up, rivets, screws or weld joints superimpose their echoes to the useful signal or useful echo. Hence note a sufficient distance of the sensor to the vessel wall.

We recommend to choose the sensor distance such that there are no installations or the vessel wall within the inner emission cone.

In products with bad reflection conditions, it is useful that there are also no interfering installations within the outer emission cone. Note chapter "4.1 General installation instructions - Emission cone and false reflections“.

Foam generation

Strong, dense and creamy foam on the product can cause wrong measurements. Provide measures to avoid foam or measure in a bypass pipe. Check if necessary the use of another measuring principle, e.g. capacitive electrodes or hydrostatic pressure transmitters.

5 Electrical connection

5.1 Connection and connection cable

Safety information

Ensure that the instrument is in currentless condition. Always switch off the power supply before you carry out terminal work on the radar sensors. Protect yourself and the instrument, especially when you use sensors which do not work with low voltage.

Skilled staff

Instruments which are not operated with a protective low voltage must only be connected by skilled staff.

Connection

A standard two-wire cable with max. 2,5 mm can be used for connection. Very often the "Electromagnetic pollution“ by electronic actuators, energy lines and transmitting stations is so considerable that the two-wire cable should be screened.

We recommend to use a screening. This screening prevents against future interferences (figure 1).

It is favourable to earth the screens on both ends. However it must be noted that no earth compensation currents flow via the sensor cable screens (figure 2). Earth compensation currents can be avoided by connecting the cable screen in case of earthing on both sides on one earthing side (e.g. in the switching cabinet) via a capacitor (e.g. 0,1␣ µF; 250␣ V) to earth potential. Use a very low impedance earth connection (foundation, plate or mains earth).

Ex-protection

If an instrument is used in hazardous areas, the appropriate regulations, conformity certificates and type approvals for systems in Ex-areas must be noted (e.g. DIN␣ 0165).

Electrical connection

Connection cable

Note that the connection cables must be specified for the expected operating conditions in your systems. The cable must have an outer diameter of 5␣ …␣ 9␣ mm (1/5 to 1/3␣ inch) or with Ex␣ d-housing 3,1␣ …␣ 8,7␣ mm (0,12␣ …␣ 0,34␣ inch). Otherwise the seal effect of the cable entry will not be ensured.

Cables for intrinsically safe circuits must be marked blue and must not be used for other circuits.

Earth conductor terminal

On all VEGAPULS 56 sensors the earth conductor terminal is galvanically connected to

the metal process connection.

5.2 Connection of the sensor

After having mounted the sensor in the measuring position according to the instructions in chapter "4 Mounting and installation“ loosen the closing screw on top of the sensor. The sensor cover with the optional display can then be opened. Unscrew the compression screw and shift the screw over the approx. 10 cm dismantled connection cable. The compression screw of the cable entry is protected with a safety lock-in position against automatic loosening.

Now loop the cable through the cable entry into the sensor. Screw the compression screw again to the cable entry and clamp the dismantled wires of the cable to the appropriate terminal positions.

The terminals operate without terminal screw. Press the white opening buckets with a small screwdriver and insert the copper core of the connection line into the terminal opening. Check the position of the lines in the terminal position by slightly pulling on the connection lines.

6 Set-up

6.1 Adjustment structure

VEGAPULS 56 radar sensors can be adjusted with

- PC (adjustment program VVO),

- detachable adjustment module MINICOM or

- signal conditioning instrument VEGAMET.

The adjustment must only be carried out with one adjustment medium at the same time.

Adjustment with PC

The PC with adjustment program VVO (VEGA Visual Operating) can be connected to the:

- sensor

- signal line

- signal conditioning instrument VEGAMET 514V/515V

- processing system VEGALOG 571

With the adjustment program VVO (VEGA Visual Operating) on the PC you can adjust the radar sensors in a very comfortable way. The PC communicates via the interface converter VEGACONNECT␣ 2 with the sensor and the signal conditioning instrument or with the standard RS␣ 232-interface cable, with the processing system VEGALOG and all connected sensors. Therefore a digital adjustment signal is superimposed to the signal and supply line of the sensors. The adjustment can be therefore made directly on the sensor, on any individual position of the signal line or on the processing system VEGAMET or VEGALOG.

Adjustment with the signal conditioning instrument VEGAMET

Like with the adjustment program VVO, sensor and signal conditioning instrument VEGAMET can be adjusted with the 6-key adjustment field on the signal conditioning instrument. The adjustment is possible in the same function volume than with the adjustment program VVO on the PC.

Set-up

Adjustment with the adjustment module MINICOM

With the adjustment module MINICOM you adjust directly in the sensor or in the external indicating instrument VEGADIS 50. The adjustment module MINICOM enables with the 6-key adjustment field with text display the parameter adjustment of the sensor in the same function volume as with the adjustment program VVO or the signal conditioning instrument VEGAMET, however not the configuration of the measuring system.

The adjustment of the signal conditioning instrument is only possible with the adjustment program VVO or the 6-key adjustment field on the signal conditioning instrument.

Independent whether you set-up a measuring system (unit of sensor and signal conditioning instrument VEGAMET or processing system VEGALOG) with the adjustment software VVO or with the signal conditioning instrument, the adjustment procedure is always the same:

- first of all configure a measuring system in the menu "Configuration“ and then

- carry out the parameter adjustment of the sensor in the menu "Instrument data“.

Before starting with the set-up: Do not be confused by the many pictures, adjustment steps and menus on the following pages. Carry out the set-up with the PC step-by-step and soon you will no more require the following pages.

48 VEGAPULS 56V

Set-up

6.2 Adjustment with the PC on VEGAMET

For connection of the PC to the signal conditioning instrument the interface converter VEGACONNECT 2 is required. The PC communicates via the interface converter with the signal conditioning instrument and with the connected sensor (s).

The individual adjustment steps are marked in the following with a dot:

• Choose …

• Start …

• Click to …

Now start:

• Connect the standard plug of VEGACON-

NECT 2 (9-pole) with the interface COM 1 or COM 2 of your PC.

• Insert the two small pin plugs of VEGA-

CONNECT 2 into the CONNECT-sockets on the front side of the signal conditioning instrument.

• Now switch on the power supply of the

signal conditioning instrument.

After approx. 1␣ …␣ 2 minutes (self-check) the measuring system is generally in operating condition and displays measured values.

6.3 Adjustment with MINICOM or VEGAMET

Beside the PC VEGAPULS 56V radar sensors can be also adjusted

- with the detachable small adjustment mod-

ule MINICOM

- or with the signal conditioning instrument

VEGAMET.

For the adjustment with the signal conditioning instrument VEGAMET all adjustment options are available like with the PC. The adjustment differs just in the appearance however not in the functionality.

With the adjustment module MINICOM all sensor relevant adjustments are possible (adjustment, operating range, measuring conditions, sensor indication scaling, linearisation or false echo storage).

Not possible however are the adjustment steps relating to the configuration of the signal conditioning instrument VEGAMET or the processing system VEGALOG and their signal processing (configuration of the inputs and outputs, linearisation curves, simulation…).

VEGAMET and MINICOM are adjusted with 6 keys. A small display gives beside the measured value a short feedback on the menu point or the figure of a menu adjustment.

Although the information quantity of the small display cannot be compared with the adjustment program VVO, there will be no problems with the adjustment according to the following menu plans of VEGAMET 515V and MINICOM. Perhaps you will carry out your adjustments more quickly and direct with the 6-key adjustment field than with the PC.

The most important adjustment steps

On page 66␣ …␣ 73 you see the complete menu plan of the signal conditioning instrument VEGAMET 515V as well as the adjustment module MINICOM. The menu plan of the signal conditioning instrument VEGAMET 514V is nearly identical (see operating instruction to the signal conditioning instrument 514V).

Set-up the sensor in the following numerical sequence. The appropriate numbers are stated in the menu plans on page 66␣ …␣ 73.

Note:

The items in brackets are only accessible with the signal conditioning instrument VEGAMET. The items with a bracket can be adjusted in addition with the adjustment module MINICOM.

1a Configuration measurement loop

(menu plan page 68)

1b Configuration input

First of all you have to inform the signal conditioning instrument (only VEGAMET 515V) to which input (input 1 or input 2) the sensor is connected. Proceed according to chapter "6.1 Configuration measurement loop“ in the operating instruction VEGAMET 515V (menu plan page 68).

2) Measurement in standpipe

Adjustments are only required when the sensor is mounted to a standpipe. With the measurement in a standpipe the running time of the radar signal changes which is dependent on the inner resistance of the standpipe. Enter the distance from the sensor flange to the medium. Then the sensor calculates a precise running time correction and provides exact level values (menu plan page 72).

3 Adjustment

Under the menu point " form the sensor in which measuring range it should operate. You can carry out the adjustment with or without medium. Generally you will carry out the adjustment without medium as you can adjust without filling cycle.

8) False echo storage

A false echo storage is only useful when false echo sources such as e.g. struts must be reduced if not possible in another way (correction of the installation position). With the creation of a false echo storage you cause the sensor electronics to learn the false echoes and to save them in an internal database. The sensor electronics treats these (false) echoes different than the useful echo and gates them out (menu plan page 72).

9) Useful and noise level

In the menu

Ampl.: Means amplitude of the product echo

in dB (useful level)

S-N: Means Signal-Noise, i.e. the useful

level minus the level of the background noise

The larger the S-N-value (distance of the amplitude useful level to noise level), the better your measurement: > 50 dB Measurement very good 40 … 50 dB Measurement good 20 … 40 dB Measurement satisfactory 10 … 20 dB Measurement sufficient 5 … 10 dB Measurement bad < 5 dB Measurement very bad

Example:

Ampl. = 68 dB S-N = 53 dB

This means that the noise level is only 68 dB – 53 dB = 15 dB.

53!dB signal distance mean a good reliability.

6.4 Adjustment with the PC on VEGALOG

For connection of the PC to the processing system VEGALOG you require a standard RS␣ 232 DTE-DTE (Data Terminal Equipment) interface cable. With the cable you connect the PC with the processing system VEGALOG.

--- 9 9 ---

Beside the measured values also the adjustment signals are transmitted digitally via the signal and supply line between sensor and processing system. The adjustment program VVO communicates therefore with the processing system and all connected sensors. In chapter "2.2 Configuration of measuring systems“ the connection of the PC in the various coordinations is shown.

The first steps of the set-up with the PC, in conjunction with the processing system VEGALOG correspond to the adjustment in chapter "6.2 Adjustment with the PC on VEGAMET“.

• Now start the adjustment software VVO on your PC.

Note:

When there is no sensor connection, please check:

- if the processing system is fed with supply voltage?

- if you use erroneously a wrong RS␣ 232cable instead of the VEGA RS␣ 232-connection cable?

If the VVO (adjustment software) gets for the first time in contact with the processing system, you are asked if the data from the processing system should be transferred to the PC.

• Click to "

Ye s

“.

When you connect VVO to a VEGALOG on which data had been already saved, you get a message if you want transfer the saved data from the PC to the VEGALOG or the data from the VEGALOG to PC.

• Click to "OK“ and you are in the "

Configuration/Program/

• Connect the standard output of your PC via the standard RS␣ 232-interlink cable (9pole) with the processing system VEGALOG.

• Now switch on the power supply of the processing system.

After approx. 1␣ …␣ 2 minutes (self-check) the measuring system consisting of processing system and sensors is generally ready for operation and the sensors show measured values.

Configuration

The adjustment of a radar sensor on a VEGALOG with the PC corresponds generally to the adjustment of a radar sensor on the signal conditioning instrument, like in chapter "6.2 Adjustment with the PC on VEGAMET“. The difference is just the increased configuration requirement of VEGALOG. A number of possible sensor inputs and signal outputs as well as different processing routines are possible and must be coordinated.
