3 .2 Principle of operation
VEGAFLEX 62 is a level sensor with cable or rod probe for continuous
level measurement.
It is designed for industrial use in all areas of process technology and
can be used equally well in liquids or solids.
High frequency microwave pulses are guided along a steel rope or a
rod. Upon reaching the product surface, the microwave pulses are
reflected. The running time is evaluated by the instrument and
outputted as distance.
Power is supplied via the H1 Fieldbus. A two-wire cable according to
Fieldbus specification serves as carrier of both power and digital data
for multiple sensors. This cable can be operated in two versions:
l via an H1 interface card in the control system and additional power
supply
l via a Linking device with HSE (High speed Ethernet) and
additional power supply according to IEC 61158-2
