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.

1.2 Application features
Applications
• Level measurement of all liquids
• Level measurement of solids
(only short measuring distances) such as
e.g.:
coal, ore, stones, stone dust, cement,
gravel, crushed stones, sand, sugar, salt,
cereals, flour, granules, powder, dusts,
saw dust, wood chips
• Flow measurement on different flumes
• Gauge measurement, distance measurement, object monitoring and conveyor belt
monitoring
Two-wire technology
• Supply and output signal on one two-wire
line (Loop powered)
• 4 … 20 mA-output signal
Rugged and precise
• Unaffected by product features such as
density, conductivity, dielectric constant …
• Suitable for aggressive substances
• Measuring ranges 0,25 m … 15 m
Adjustment choice
• With adjustment software VEGA Visual
Operating (VVO) on PC
• 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.
