1 Product description

1.1 Function

Radio detection 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.
Product description - Function
1 ns
278 ns
Meas. 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.
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.
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.
Time transformation
Hence it is possible for the VEGAPULS 50 radar sensors to process the slow-motion pictures of the sensor environment precisely and in detail in cycles of 0,5 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 conductive product (air) and spread like light with light velocity.
4 VEGAPULS 51 V … 54 V
Product description - Function
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 reflection for a reliable measurement.
All products with a dielectric constant figure ε of more than 2,0 reflect radar impulses sufficiently (note: air has a dielectric constand figure ε The signal reflection increases with the
of 1).
r
conductivity or with the dielectric constant figure of the product. Hence virtually all products can be measured.
ε
Reflected radar power dependent on the dielectric constant figure of the measured product
Continuous and reliable
Unaffected by temperature, pressure and individual gas atmospheres, VEGAPULS radar sensors are used for quick and reliable continuous level measurement of various products.

Due to the standard flanges from DN 50 to DN 250, ANSI 2" to ANSI 10" or G 11/2 A and 11/2" NPT the sensor antenna systems are adapted to the various measured products and measurement environments.
VEGAPULS 50 enable level measurement with radar sensors on systems where radar sensors had not been used before due to price reasons.
High-quality materials withstand also extremely chemical and physical conditions. The sensors deliver reliably, precisely and longterm stable, reproducible analogue or di­gital level signals.

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 is hence carried out with
- the PC and adjustment program VVO
- 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 PC with adjustment program VVO (VEGA Visual Ope- rating) under Windows®. The program leads quickly through the adjustment and parameter adjustment via pictures, graphics and process visualisations.

Adjustment with the PC on the digital signal and supply line between the sensors and the signal conditioning instrument VEGAMET
The PC can be connected to any individual position of the system or the signal line. It is hence connected with the two-wire PC­interface converter VEGACONNECT 2 to the sensor, to the signal line or to the signal conditioning instrument.

Types and versions

2 Types and versions

VEGAPULS series 50 sensors are a new developed generation of very compact, small radar sensors. With only very narrow space requirements they are developed for short meas. distances (0 … 20 m) and for standard applications such as storage tanks and buffer tanks.
Due to the small housing dimensions and process connections, the compact sensors monitor your levels very price favourably. With the integral indication and the many features of the "big brothers" of VEGAPULS series 64 and especially of VEGAPULS series 81, they open the advantages of a radar level measurement for applications in which the special adavantages of radar were not possible, due to price reasons.
VEGAPULS 50 radar sensors dominate the two-wire technology perfectly. They are the first radar sensors transmitting supply voltage and output signal via one two-wire line. As output or meas. signal they provide a digital output signal.

2.1 Type survey

The antenna is the eye of the radar sensor.
Four antenna systems are available for diffe­rent applications and process requirements. Each system differs in the physical features.
Rod antenna
Rod antennas with high chemical resistance require smallest flange dimensions (DN 50). The antenna rod and the wetted flange parts are made of PTFE, PP or PPS so that the rod antenna can be easily cleaned and is insensitive to condensation. The rod antenna is suitable for pressures up to 16 bar and temperatures up to 150°C.

Horn antenna
VEGAPULS 54
Horn antennas are best suited for most applications. They focus the radar signals very well. Manufactured of
1.4571 (stst) they are very rugged and physically as well as chemically resistant. They are suitable for pressures up to 40 bar and for product temperatures up to 150°C.
VEGAPULS 54 (pipe antenna/ standpipe)
Pipe antenna
VEGAPULS 54 (pipe antenna/ standpipe)
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 especially suitable for products with heavy product movements or products with low dielectric constant figure. The antenna can be with or without horn. Versions with horn characterize by very
good antenna gain. A very good reliability can be achieved even in case of products with very bad reflection features.
The meas. 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.

Types and versions - Configuration of meas. systems

2.2 Configuration of measuring systems

Which radar sensor you use depends on your process requirements and installation conditions as well as on the requirements of your control or processing system.
On sensors with digital output signal like VEGAPULS 51 V … 54 V a meas. system consists of a sensor and a processing unit. The processing unit (the signal conditioning instrument VEGAMET or the processing system VEGALOG) evaluates the level pro­portional digital meas. signal in a number of routines and provides then the levels as individual current, voltage or switching signals.
On the following pages you find the various instrument configurations which are called in the following meas. system and which are partly shown with a signal processing.
• 2 sensors on one two-wire line
(page 14)
• 2 sensors in Ex on one two-wire line
(page 15)
• 15 sensors on one two-wire line

Series 50 sensors require for operation in Ex­areas Ex-separator VEGATRENN 548 V Ex, providing intrinsically safe Ex-circuits to the sensors. On the Ex-separtor VEGATRENN 548 V up to 9 sensors can be connected in groups with three sensors each (see page 17).
Note to page 15…17:
2)
Sensor lines should be looped in screened cables. It is recommended to earth the cable screens on both ends. However it must be noted that no earth compensation currents flow over the screen. Earth compensation currents are avoided in case of earthing on both ends by connecting the cable screen on one earth side (e.g. in the switching cabinet) via a capacitor (e.g. 1 µF; 100 V) with the earth potential.
Sensor lines leading to the same separator card, can be looped together in one screened multiple wire cable. Sensor lines leading to other separator cards must be looped in separate screened cables.

4.1 General installation instructions

Measuring range
The reference pane for the measuring range is the flange face (type 53/54) or the seal shoulder of the thread (type 51/52). The max. measuring range is 0 … 20 m, dependent on the sensor type. The min. distance to the medium must be 5 cm.
For measurements in surge or bypass pipes (pipe antenna), the max. meas. distance is reduced. Note that for measurements where the medium reaches the antenna, build-up on the antenna is possible which can cause measurement errors.

False reflections
Flat obstructions and struts cause large false reflections. They reflect the radar signal with high amplitude.
Round profile interfering surfaces have a dif­fuse reflection of the radar signals and cause false reflections with low density. Hence they are less critical than reflections from a flat surface. If flat obstructions in the range of the radar signals cannot be avoided, it is recommended to reflect the interfering signals with a deflector.

Profiles with smooth interfering surfaces cause large false signals
Due to this scattering the interfering signals will be low in amplitude and diffuse so that they can be filtered out by the sensor.

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

The PTEF (Teflon) rod antenna is well suited to chemically aggressive products such as lyes and acids. Applications in the food processing industry with aseptic vessel conditions are catered for with the Teflon rod antenna close tolerance and crevice free construction.
For measurements of liquids with the Teflon rod antenna, the mounting is made on a straight DIN-socket piece. The socket however must not be longer than 150 mm (when using a longer antenna, not longer than 250 mm). The rod antenna is available in flange sizes of DN 50, DN 80 and DN 100.

Mounting and installation - Measurement in standpipe
As an alternative to the surge pipe in the vessel, a pipe antenna outside the vessel is possible as bypass pipe. Direct the sensor such that the type plate is in one axis with the pipe holes or the pipe connection openings. The polarization of the radar signals enables considerably more stable measurements with this directing. Note that with a measurement in the surge or bypass pipe the max. measuring range is reduced by 5 … 20 % (e.g. DN 50: 16 m instead of 20 m and DN 100 only 19 m instead of 20 m).

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. The pipe must be smooth inside. Roughnesses or joints must be removed carefully as otherwise strong false echoes and build-up will be caused.

4.4 False echoes

The installation place of the radar sensor must be selected such that no struts or inflowing material cross the radar signals. The following examples show frequent meas. 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.

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
Strong product movements
Products which can cause slight build-up can be measured by using a meas. pipe with 100 mm nominal width and more. In a meas. 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".

4.5 Installation error

Socket piece too long
When mounting the antenna in a too long socket piece, strong false reflections are caused, aggravating a measurement. Note that the horn antenna protrudes at least 10 mm out of the socket piece. When using a rod antenna, the socket piece must have a length of max. 100 or 60 mm (with a rod length of 545 mm the length of the socket piece must be max. 250 mm).

Correct Wrong
Ladder

Ladder
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.
In case of good reflection conditions (liquids without vessel installations) we recommend to select the sensor distance so that there is no vessel wall within the inner emission cone. For liquids with worse reflection conditions it is useful that there are also no interfering installations within the outer emission cone. Note chapter "4.1 General installation instructions".
Foam generation
Strong, dense and creamy foam on the product can cause faulty 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 unpressurized before you start work. Always switch off the power supply before you carry out clamping work on the radar sensors. Protect yourself and the instruments. Especially when you use sensors which do not work with low voltage.
Skilled staff
Instruments operated in Ex-areas must only be connected by skilled staff. This staff must note the installation regulations and the attached type approvals and conformity certificates.
Connection
A standard two-wire cable with max. 2,5 mm can be used for connection. Very often "Electromagnetic pollution" by electronic actuators, energy lines and transmitting stations is so considerable that the two-wire line must be screened.
We recommend to use a screening. This screening prevents against future interferences. It is useful to earth the cable screens on both ends, however it must be noted that no earth compensation currents flow via the sensor cable screens. You avoid earth compensation currents by connecting the cable screen on one earth side (e.g. in the switching cabinet) via a capacitor (e.g. 1 µF; 100 V) with earth potential in case of earthing on two ends. 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 sensors and separators or safety barriers must be noted (e.g. DIN VDE 0165). Sensors used in Ex-area must only be operated on intrinsically safe circuits. The permissible electrical values are stated in the conformity certificate or the type approval.
Connection cable
Note that the connection cables must be specified for the expected operating temperatures in your systems. The cable must have an outer diameter of 5 … 9 mm. Otherwise the seal effect of the cable entry will not be ensured.
2
Cables for intrinsically safe circuits must be marked blue and must not be used for other circuits.
Earth conductor terminal
On VEGAPULS 51/52 sensors with a 11/2" thread of plastic, the earth conductor terminal is galvanically isolated. On all VEGAPULS 53/54 sensors as well as VEGAPULS 51/52 sensors with metal thread, the earth conductor terminal is galvanically connected with the metal process connection.
VEGAPULS 51 V … 54 V 41
5.2 Connection of the sensor
After having mounted the sensor in the measuring position acc. to the instructions in chapter "4 Mounting and installation", loosen the closing screw on the top of the sensor. The sensor cover with the optional indicating display can then be opened. Unscrew the compression screw and shift the screw over the approx. 10 cm dismantled connection cable. The compression screw is protected with a safety lock-in position against automatic loosening.
Voltage supply and digital measuring signal
Electrical connection - Connection of the sensor
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.

For connection of a PC to a signal conditioning instrument you require the interface adapter VEGACONNECT 2. The PC communicates via the interface adapter VEGACONNECT 2 with the signal conditioning instrument and the sensor. Hence a digital adjustment signal is superimposed to the signal and supply line between sensor and signal conditioning instrument. In chapter "2.2 Configuration of measuring systems" the connection of the PC in different coordinations is shown.
In any case you are requested to enter or enquire something, this is marked in the following with a dot, such as e.g.:

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

Hence the sensor electronics has two characteristics points (MIN and MAX), out of which a linear proportionality between product distance and the percentage filling of a vessel is generated. However the characteristics points must not be at 0 % and 100 % but the difference should be as large as possible (e.g. at 20 % and at 80 %). The min. product distance of the characteristics point for min./max. adjustment should be 50 mm. When the characteristics points are too close together, the possible meas. error increases. It is hence suitable to carry out the adjustment at 0 % and at 100 %.

On page 62 you see the complete menu plan of the signal conditioning instrument VEGAMET 515 V as well as the adjustment module MINICOM. The menu plan of the signal conditioning instrument VEGAMET 514V is nearly identical (see operating instruction to signal conditioning instruments VEGAMET 514 V).
Set-up the sensor in the following numbered sequence. The appropriate numbers are stated in the menu plans on page 64 … 71.
The items in brackets can only be carried out with the signal conditioning instrument VEGAMET however not with the adjustment module MINICOM.

Set-up - Adjustment with MINICOM or VEGAMET
Following short explanations to the set-up steps 1 … 9.
1. Configuration of the input
First of all you have to inform the signal conditioning instrument (only VEGAMET 515 V) to which input the sensor is connected.
2.) Operating range
Without special adjustment, the operating range corresponds to the meas. range. The meas. range has already been adjusted with the min./max. adjustment. Generally it is useful to choose the operating range slightly bigger (approx. 5 %) than the meas. range. Example: Min./max. adjustment: 0,500 … 3,400 m; adjust operating range to approx. 0,400 … 3,500 m.
3.) Measuring conditions
see menu plan no. 3) on page 74
4.) Adjustment
Under the menu point " the sensor in which meas. range it should operate. The adjustment can be carried out with and without medium. Generally you will carry out the adjustment without medium as you can adjust without filling cycle.

A linear dependence between the percentage value of the level distance and the percentage value of the filling volume is preadjusted.

68 dB – 53 dB = 15 dB
With 15 dB signal distance there is a high reliability.
7.) False echo memory
A false echo memory is always useful when false echo sources such as e.g. struts must be reduced. With the creation of a false echo memory you cause the sensor electronics to note the false echoes and to save them in an internal database. The sensor electronics treats these (false) echoes differently than the useful echo and gates them out.

9. Conditioning / Scaling of the sensor display
The menu point "Conditioning" in the MINICOM-menu only relates to the SENSOR-display and will be overwritten by the adjustments in the signal conditioning instrument.

Set-up - Adjustment with the PC on VEGALOG
The first set-up steps with the PC in conjunction with the processing system VEGALOG correspond to the adjustment in chapter "
MINICOM
6.2 Adjustment with VEGAMET or
".
• Connect the standard output of your PC with the standard RS232-interlink cable (9­pole) to the processing system VEGALOG.
• Now switch on the power supply of the processing system.
After approx. 1…2 minutes (selfcheck) the meas. system consisting of processing system and sensors is normally ready for operation and the sensors indicate measured values.
Via the signal and supply lines between sensor and processing system also adjustment signals are transmitted digitally beside the measured values. The adjustment program VVO can then communicate with the processing system and all connected sensors. In chapter "2.2 Configuration of measuring systems" the connection of the PC to the various meas. systems is shown.

The adjustment of a radar sensor on a VEGALOG with the PC generally correponds to the adjustment of a radar sensor on the signal conditioning instrument, like in chapter "
6.2 Adjustment with PC on VEGAMET
The difference is just in the higher configuration requirement of VEGALOG. A number of possible sensor inputs and signal outputs as well as various processing routines must be coordinated. First of all it must be defined which sensor (input) whould be processed where and how.
