It is designed for industrial use in all areas of process
technology and can be used in non-conductive 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 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
