FTW31

The sensor rods are supplied with alternating voltage. When conductive liquid is present, an electrical connection is established between the grounding rod and the MAX sensor rod, generating a measurable current that activates the Liquipoint T switch. For level limit detection, the switch changes state immediately when the liquid no longer covers the MIN point. For two-point control, the switch changes state only when the liquid no longer covers both the MAX and MIN points. The alternating voltage prevents sensor rod corrosion and medium electrolysis. The sealed zero-potential circuit between the sensor rods and electronic insert ensures that tank wall material has no influence on measurement. During operation, contact between sensor rods is completely safe.

Foundamental

The Liquipoint FTW31 is designed for simple and reliable level limit detection of conductive liquids. Its multi-point detection function (up to 5 measuring rods) expands the measurement range and provides greater application flexibility.
