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.
