Application
Maximum or minimum detection in tanks or piping with fluids of all types,
also in hazardous areas and in the food and pharmaceuticals industries.
Function and system design
The tuning fork of the sensor oscillates in resonance frequency. This
frequency is reduced when covered with liquid. The change in frequency
then activates a limit switch.
The device possesses a digital output with PROFIBUS PA protocol.
