Principle of operation

VEGASON 61 is an ultrasonic sensor for continuous level measure-
ment. It is suitable for liquids and solids in virtually all industries,
particularly in the water and waste water industry.
The transducer of the ultrasonic sensor transmits short ultrasonic
pulses to the measured product. These pulses are reflected by
medium surface and received back by the transducer as echoes.
The running time of the ultrasonic pulses from emission to reception
is proportional to the distance and hence the level. The determined
level is converted into an appropriate output signal and outputted as
measured value.
Four-wire electronics with separate power supply.
The supply voltage range can differ depending on the instrument
version.
The data for power supply are specified in chapter " Technical data".
Measured value transmission is carried out via the 4 ... 20 mA/HART
output separate from power supply.
The backlight of the display and adjustment module is powered by the
sensor. The prerequisite for this is a supply voltage at a certain level.
The exact voltage specifications are stated in chapter " Technical
data".

Adjustment

The instrument can be adjusted with the following adjustment media:
•
With the display and adjustment module
•
with the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard, e.g. PACTware and
PC
•
With manufacturer-specific adjustment programs AMS™ or PDM
•
With a HART handheld
