3.2Principle of operation
VEGAFLEX 65 is a level sensor with pipe probe for continuous
level measurement.
It is designed for industrial use in all areas of process
technology and can be used in liquids.
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 H1Fieldbus.Atwo-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:
lvia an H1interface card in the control system and
additional power supply
lvia a Linking device with HSE (High speed Ethernet)and
additional power supply according to IEC 61158-2
