1.1 Function
The continuous level measurement with ultra-
sonic 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 ultra-
sonic pulses. The transducers work as trans-
mitter and receiver. As receiver the trans-
ducers are high sensitivity piezo-micro-
phones.
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 tem-
perature influence, the transducer also con-
tinuously 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 instru-
ment shows the precise level with the ana-
logue 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-
ates, like the integral indication, independent
of the 4 … 20 mA-output signal, and indi-
vidual parameter adjustment is possible.
emission - reflection - receipt
Meas.
distance
The measuring electronics precisely calculate
the distance between transducer and me-
dium from the speed of sound and the actu-
ally detected running time of the emitted
sound impulse. The distance is then con-
verted into a level proportional signal and
provided according to the sensor parameter
adjustment as precise scaled level.

1.3 Adjustment
Each measuring distance is different, there-
fore 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 adjust-
ments 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 MINI-
COM
- 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 ad-
justment and parameter adjustment via pic-
tures, graphics and process visualisations.

wire sensor)

Product description
The PC can be connected to any individual
position of the system or the signal line. It is
thereby connected with the two-wire PC-
interface converter VEGACONNECT 2 to the
sensor or to the signal line.
The adjustment and parameter adjustment
data can be saved with the adjustment soft-
ware on the PC and protected with pass-
words. If required, the adjustment can be
transmitted quickly to other sensors.
Adjustment with adjustment module
MINICOM
With the (3,2 cm x 6,7 cm) 6-key adjustment
module with display you can carry out the
adjustment in clear text.
The adjustment module can be plugged into
the ultrasonic sensor or into the optional
external indicating instrument.
DCS
By removing the adjustment module unau-
thorised adjustments are avoided.

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-Device-
Description) 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 mA-
output signal line or insert the two communi-
cation lines of the HART®-handheld into the
adjustment sockets on the sensor.

2 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 stand-
ard 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-con-
tact 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 mA-
output signal is available as output or meas-
uring signal.

2.2 Configuration of meas. systems
A meas. system consists of a sensor with a
4 …20 mA signal output and a unit evaluat-
ing or processing the level proportional cur-
rent signal.
On the following pages you will see the in-
strument configurations called meas. system
which are shown in the following partly with a
signal processing.
Meas. systems in two-wire technology:
•4 …20 mA drawing without processing
unit, (bottom)
•4 …20 mA on active DCS, (page 12)
•4 …20 mA on active DCS (Ex-area),
(page 13)
•4 …20 mA on passive DCS, (page 14)
•4 …20 mA on indicating instrument

Meas. systems in four-wire technology:
•4 …20 mA drawing without signal condi-
tioning instrument, (page 16)

Types and versions
Meas. systems with VEGASON 51K … 53K
•Two-wire technology (loop powered), supply and output signal via a two-wire line
•Output signal 4 …20 mA (passive)
•Optional external indicating instrument with analogue and digital indication (can be mounted
up to 25 m away from the sensor)
•Adjustment with PC, HART®-handheld or adjustment module MINICOM (can be plugged into
the sensor or in the external indicating instrument VEGADIS 50)
1) If the resistors of the processing
systems connected to the
4 …20 mA-signal output are less
than 200 W, a resistor of 250 W to
350 Wmust be connected to the
connection line during adjustment.
The digital adjustment signal would
be extremely damped or short-
circuited via too small input
resistors of the connected
processing system which means
that the digital communication with
the PC could no longer be
ensured.
