3.2 Principle of operation
VEGASON 66 is an ultrasonic sensor for continuous level
measurement. It is particularly suitable for solids, but also good
for liquids.
The transducer of the ultrasonic sensor transmits short
ultrasonic pulses to the measured product. These pulses are
reflected by product surface and received again by the
rtansducer as echoes. The running time of the ultrasonic
pulases 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 exact range is stated in the "Technical
data" in the "Supplement".
Measured value transmission is carried out via the 4 … 20 mA/
HART output separate from power supply.
