rinciple of operation
VEGASON
63
is an ultrasonic sensor for continuous level
measurement
.
I
t is suitable for liquids and solids in practically
all industries
.
T
he transducer of the ultrasonic sensor transmits short
ultrasonic pulses to the measured product
.
T
hese pulses are
re
fl
ected by product surface and received again by the
rtansducer as echoes
.
T
he running time of the ultrasonic
pulases from emission to reception is proportional to the
distance and hence the level
.
T
he determined level is
converted into an appropriate output signal and outputted as
measured value
.
