1 Product description

1.1 Function

The continuous level measurement with ultrasonic sensors is based on the running time measurement of ultrasonic pulses.

Measuring principle

Piezoceramic high performance transducers emit focused ultrasonic pulses which are reflected by the surface of solids and liquids. The measuring electronics prepare a precise picture of the environment from the running time and the signal form of the reflected ultrasonic pulses. The transducers work as transmitter and receiver. As receiver the transducers are high sensitivity piezo-microphones.

Meas. distance

Product description

In order to be prepared for the different measuring distances and requirements, the instruments operate with emitting frequencies of 34 kHz up to 70 kHz.

As the sound velocity is subjected to a temperature influence, the transducer also continuously detects the ambient temperature so that the level is precisely provided even in case of varying ambient temperature.

Output signals

The level proportional measuring signal is provided as 4 … 20 mA-output signal.

The parameter adjustment of the analogue 4 … 20 mA-signal is individually possible and reflects the measuring range or the adjusted adjustment range of the sensor.

Measured value indication

If desired, an indicating instrument for direct lobal survey can be mounted on to the series 50 ultrasonic sensors. The indicating instrument shows the precise level with the analogue bar-graph and with the digital figure. In addition to the indication in the sensor itself, you can have the level displayed with the external indicating instrument VEGADIS 50 up to 25 m away from the sensor.

The external measured value indication oper-

emission - reflection - receipt

The measuring electronics precisely calculate the distance between transducer and medium from the speed of sound and the actually detected running time of the emitted sound impulse. The distance is then converted into a level proportional signal and provided according to the sensor parameter adjustment as precise scaled level.

ates, like the integral indication, independent of the 4 … 20 mA-output signal, and individual parameter adjustment is possible.

• With detachable adjustment module MINICOM

• With the HART®-Handheld

• Measured value indication integrated in the sensor

• Optional indication separate from the sensor

1.3 Adjustment

Each measuring distance is different, therefore each ultrasonic sensor must be given some basic information on the application and the environment, e.g. you need to inform the sensor which level means “empty“ and which level “full“. Apart from this “empty and full adjustment“, a number of other adjustments can also be carried out with VEGASON ultrasonic sensors.

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

- the PC

- the detachable adjustment module MINICOM

- the HART®--Handheld

Adjustment with PC

The set-up and adjustment of the ultrasonic sensors is generally made on the PC with the adjustment program VEGA Visual Operating (VVO) under Windows®. The program leads quickly through the adjustment and parameter adjustment via pictures, graphics and process visualisations.

Adjustment with the PC on the analogue 4 … 20 mAsignal and supply line or directly on the sensor (fourwire sensor)

The PC can be connected to any individual position of the system or the signal line. It is thereby connected with the two-wire PCinterface converter VEGACONNECT 2 to the sensor or to the signal line.

The adjustment and parameter adjustment data can be saved with the adjustment software on the PC and protected with passwords. If required, the adjustment can be transmitted quickly to other sensors.

Adjustment with HART®-Handheld

Series 50 sensors with 4 … 20 mA output signal can also be adjusted with the HART®Handheld. A special DDD (Data-DeviceDescription) is not necessary as the sensors can be adjusted with the HART®-standard menus of the handheld.

For adjustment, just connect the HART®Handheld in any position of the 4 … 20 mAoutput signal line or insert the two communication lines of the HART®-handheld into the adjustment sockets on the sensor.

2 Types and versions

Types and versions

VEGASON series 50 sensors are a newly developed generation of very compact, small ultrasonic sensors. With very narrow space requirements, they are designed for short meas. distances (0 … 15 m) and for standard applications such as storage tanks, gauge measurement 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 VEGASON series 80, they offer the advantages of an ultrasonic level measurement for applications where the special advantages of a non-contact measurement are not applicable for price reasons.

VEGASON 50 ultrasonic sensors control the two-wire technology perfectly. The supply voltage and the output signal are transmitted via a two-wire line. An analogue 4 ... 20 mAoutput signal is available as output or measuring signal.

Any object in this beam angle causes a false echo. Within the first few metres of the beam angle, tubes, struts or other installations cause strong false echoes. At a distance of 6 m the false echo of a strut has 9-times more amplitude than at a distance of 18 m.

4.4 Socket extensions

The ultrasonic sensor requires a min. distance to the product or solid. Note this min. distance in your planning. In exceptions it is possible to reach the required min. distance and hence the desired filling height with a socket piece. However, the socket piece increases the noise level of the ultrasonic signal and can interfere with the measurement. Only provide the socket extension when there is no other possibility, and carry out the extension as shown in the following figure.

Socket extension with liquids

Chamfer the socket carefully and ensure a smooth inner side of the socket. The socket should not protrude into the measured product when pollution or measured product could stick to the socket.

;;;;;;;;;;;;;;;

;;;;;;;;;;;;;;;;

;;;;;;;;;;;;;;;

For measurements in products which do not cause any build-up, the socket extension, in form of a meas. pipe, can be permanently submerged into the measured product. The ultrasonic mesurement is then only carried out in the meas. pipe without being interfered with by vessel installations (see page 28 "Pump shaft“).

4.6 False echoes

The placing of the ultrasonic senor must be chosen so as to ensure that no mountings or in-flowing filling material crosses with the ultrasonic impulses. The following examples and instructions show the most frequent measuring problems and how to avoid them.

Vessel protrusions

Vessel forms with flat protrusions can, due to their strong false echoes, greatly effect the measurement. The placing of shields over these flat protrusions scatter the false echoes and guarantee a definite measurement.

Correct Wrong

Vessel protrusions (slope)

Intake pipes, i.e. for the mixing of materials with the flat top turned towards the sensor should be covered with an angular shield with which the false echoes are then scattered.

Vessel mountings

Vessel mountings such as, for example, a ladder often cause false echoes. When projecting the measuring point, please ensure the free access of the ultrasonic signals to the medium.

Correct Wrong

Ladder

Vessel mountings

Ladder

Vessel struts

Vessel struts, as with other vessel mountings, can cause strong false echoes which superimpose the useful echoes. Small shields effectively hinder a direct false echo reflection. The false echoes are scattered and diffused in the area and are then filtered out as "echo noise" by the measuring electronics.

Mounting on the vessel

If the sensor is mounted too close to the vessel wall, build-up and adhesion of the filling material to the vessel wall cause false echoes. Please position the sensor at a sufficient distance from the vessel wall. Please also note chapter "4.1 General installation instructions".

Correct

Build-up

Wrong

Strong product movements

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

Wrong directing to the product

Weak measuring signals are caused if the sensor is not directed to the product surface. Direct the sensor axis vertically to the product surface to achieve optimum measuring results.

Strong heat fluctuations

Strong heat fluctuations, e.g. due to the sun cause measuring errors. Provide a shield.

VEGASON 51K … 53K 33

Mounting and installation

Sensor too close to the vessel wall

if the sensor is mounted too close to the vessel wall (dimension A in diagram) strong false echoes can be caused. Build-up, rivets, screws and weld joints superimpose their echoes on the product echo or useful echo. Please ensure the sufficient distance of the sensor to the vessel wall depending on the maximum measuring distance (dimension B in diagram). In case of good reflection conditions (liquids, no vessel installation) we recommend the provision of the sensor distance according to diagram curve 1. At a max. meas. distance of, for example 10 m the distance of the transducer, according to curve 1, should be approx. 1 m. In case of solids with bad reflection conditions provide a distance to the vessel wall according to diagram curve 2. With very bad meas. conditions it could be necessary to increase the distance to the vessel wall or to gate out the false echoes additionally by a false echo storage and thereby adapt the sensor more precisely to the environment.

Distance of the transducer to the vessel wall

Parabolic effects on dished boiler head or basket arch vessels

Round or parabolic tank tops act like a parabolic mirror for the signals. If the 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 half the vessel radius from the centre.

5 Electrical connection

Electrical connection

5.1 Connection and connection cable

Safety information

Ensure that the instrument is unpressurised before you start work. Always switch off the power supply before you carry out clamping work on the ultrasonic sensors. Protect yourself and the instruments, especially when using sensors which do not operarate with low voltage.

Skilled staff

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

Connection

A standard two or four-wire cable (sensors with separate supply) with max. 2,5 mm2 can be used as connection. Very often the "electromagnetic pollution“ by electronic actuators, energy lines and transmitting stations is so considerable that the two-wire line or fourwire line should be screened.

We recommend the use of screening. This screening prevents future interferences. Only earth the cable screens on both ends (on the sensor and on the processing system) when you have determined, by measurement, that no or only lowest earth compensating currents flow via the screens. Use a very low impedance earth connection (foundation, plate or mains earth).

Ex-protection

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

Intrinsically safe circuits with more than one active instrument (instrument delivering electrical energy) must not be connected. Please note the special installation conditions (DIN 0165).

Connection cable

Note that the connection cables are specified for the expected operating temperatures in your systems. The cable must have an outer diameter of 5 … 9 mm to ensure the seal effect of the cable entry. Cables for intrinsically safe circuits must be marked blue and must not be used for other circuits.

Earth conductor terminal

On VEGASON 51/52 sensors the earth conductor terminal is galvanically isolated. The sensors are shockproof. On the VEGASON 53 sensor the earth conductor terminal is galvanically connected to the metal transducer diaphragm.

36 VEGASON 51K … 53K

Electrical connection

5.2 Connection of the sensor

After having mounted the sensor in the meas. position according 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 indication 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.

Supply voltage 4 … 20 mA (passive)

To the indicating instrument in the sensor cover or to the external indicating instrument VEGADIS 50

Now loop the cable through the cable entry into the sensor. Screw the compression screw on 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.

6.1 Adjustment structure

Series 50 ultrasonic sensors can be adjusted with

- PC (adjustment program VVO)

- with the detachable adjustment module MINICOM

- with the HART®-handheld.

The adjustment must only be carried out with one adjustment medium. If, for example you try the parameter adjustment with the MINICOM and the HART®-handheld, the adjustment will not be successful.

Adjustment program VVO

With the adjustment program VVO Visual Operating System) on the PC you can adjust the ultrasonic sensors very comfortably. The PC communicates via the interface adapter VEGACONNECT 2 with the sensor. A digital adjustment signal is therefore superimposed on the signal and supply line. The adjustment can be carried out directly on the sensor or on any individual position of the signal line.

Adjustment module MINICOM

With the adjustment module MINICOM you adjust in the sensor or in the external indicating instrument VEGADIS 50. The adjustment module enables via the text display with 6key field the adjustment in the same functions volume as with the adjustment program VVO.

(VEGA

6.2 Adjustment with PC

The instructions for the adjustment with the PC and the adjustment program VVO can be found in the manual "VEGA Visual Operating (VVO)" which is supplied with the latest adjustment software. Beside the adjustment of ultrasonic sensors, the manual "VEGA Visual Operating (VVO)" also describes the setup of all other VEGA sensors with the PC.

PC on the sensor

For connection of the PC to the sensor you need the interface adapter VEGACONNECT

2. Insert VEGACONNECT 2 into the CONNECT-socket provided in the sensor.

PC on the signal line

Connect the two-wire line of VEGACONNECT 2 to the signal or supply line of the sensor. When the resistors of the systems (DCS, current source etc.,) connected to the signal/ supply line are less than 250 Ω, a resistor of 250 … 350 Ω must be connected to the signal/supply line during adjustment. The digital signals modulated to the signal line would be considerably damped via the small system resistors or "shortcircuited" which means that the communication with the PC would be interfered with.

HART®-handheld

VEGASON 50 K ultrasonic sensors, like other HART®-protocol capable instruments, can be adjusted with the HART®-handheld. A manufacturer specific DDD (Data-Device-Description) is not required. The ultrasonic sensors are adjusted with the HART®-standard menus. All main functions are, therefore, accessible. Some functions which are rarely used such as, for example the scaling of the A/D-converter for the signal output, or the adjustment with medium, are not possible or are blocked by the HART®-handheld. These functions must be carried out with the PC or the MINICOM.

The difference between the adjustment values of the lower product distance and the upper product distance should be as big as possible, preferably at 0 % and 100 %. If the values are very close together, e.g. lower product distance at 40 % (3,102 m) and upper product distance at 45 % (3,331 m), the measurement will be inaccurate. A level characteristic is generated from the two points. Even with smallest deviations between actual product distance and adjusted product distance, the slope of the characteristics will be considerably influenced. Thereby small failures multiply with the adjustment when the adjustment points are too close together to more considerable errors at the output of the 100 %-value or the 0 %-value.

4. Operating range

Without special adjustment, the operating range corresponds to the measuring range. The measuring range has already been adjusted with the min./max. adjustment. Generally it is useful to choose a slightly bigger (approx. 5 %) operating range than the measuring range.

Example: Set min./max. adjustment to: 0,300 … 5,850 m; operating range to approx. 0,250 … 6,000 m.

5. Meas. conditions

(see menu plan no. 5)

6. Measurement in gases

Adjustment is only necessary when the measurement is made in gases (Co2, He, etc.) deviating from air. In case of measurement in gases sound the distance of the sensor to the product surface and enter in the menu point "Measurement in gases“. The sensor can then consider the modified sound velocity in gases as opposed to air and provide correct levels.

7. False echo storage

A false echo storage is always useful when false echo sources such as struts must be reduced. With the creating of a false echo storage, you authorise the sensor electronics to note the false echoes and save them in an internal database. The sensor electronics treat these (false) echoes differently from the useful echo and gates them out.

8. Useful and noise level

In the menu

you get important information on the signal quality of the level echo. The higher the "S-N“-value, the more reliable the measurement (menu plan MINICOM).

Ampl.: Means amplitude of the level echo in

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

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

Example:

Ampl. = 68 dB S-N = 53 dB

68 dB – 53 dB = 15 dB

53 dB signal distance means very good reliability.

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

6.4 Adjustment with the HART®-handheld

With each HART®-handheld you can set-up the VEGASON series 50K ultrasonic sensors like all other HART®-capable sensors. A special DDD (Data Device Description) is not necessary.

Just connect the HART®-handheld to the signal line, after having connected the sensor to power supply.

Set-up

Ri < 250 Ω

Note:

If the resistor of the power supply is less than 250 Ohm, a resistor must be looped into the signal/connection line during adjustment.

250 Ω

Connection to a VEGA-signal conditioning instrument

When you operate a HART®-capable sensor on a VEGA-signal conditioning instrument, you have to connect the sensor via a resistor according to the following table during the HART®-adjustment, to reach together with the inner resistor of the instruments the value of 250 Ohm required for the HART®-instrument.

The digital adjustment and communication signals would be short-circuited via too small resistors of the supply current source of the processing system which means that the sensor communication could not be ensured.

7.1 Simulation

To simulate a certain filling, you can call up the function "Simulation" on the adjustment module MINICOM, in the software program VVO or in the HART® handheld.

With this function, you simulate a and hence a real sensor current vessel filling level. Please note that connected instruments, such as e.g. a PLC, react according to their adjustments and will probably activate alarms or system functions.
