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).

conductivity or with the dielectric constant figure of the product. Hence virtually all products can be measured.

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

(page 16)

• 3 sensors in Ex on one two-wire line

(page 17)

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:

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.

Technical data - Approvals

3.3 Approvals

When using radar sensors in Ex and St-Exareas, the instrument must be suitable and approved for these explosion zones and applications. For the use on ships, special type approvals are available. The suitability is tested by the approval authorities and certified by approval documents.

VEGAPULS 51 V Ex (0) to 54 V Ex (0) sensors must be supplied from one intrinsically safe circuit when used in Exareas. This is ensured by the separators VEGATRENN 548 V Ex. The separator provides intrinsically safe (ia) circuits. The resistance of the signal line must not exceed 15 Ω per wire.

VEGAPULS 51 V Ex … 54 V Ex sensors are approved for Ex-Zone 1. VEGAPULS 51 V Ex 0 … 54 V Ex 0 sensors are approved for Ex-Zone 0. Please note the attached approval documents when you want to use a sensor in Ex-environment.

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.

26 VEGAPULS 51 V … 54 V

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.

A deflector causes signal scattering

Emission cone and false reflections

The radar signals are focused by the antenna system. The signals leave the antenna in conical form, similar to the beam pattern of a spotlight.

If possible provide a "clear view" inside the emission cone to the product and avoid obstructions in the first third of the cone.

Optimum measuring conditions exist when the emission cone reaches the measured product vertically and when the emission cone is free from obstructions.

Horn antenna

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

28 VEGAPULS 51 V … 54 V

Mounting and installation - Measurement of liquids

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.

Mounting on dished vessel end

Horn antenna directly on the vessel top

Dependent on the construction of the vessel, flat mounting directly on the vessel top would be a favourable solution. The top side of the vessel is the reference pane.

Rod antenna

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.
