Endress+Hauser Liquipoint T FTW31 Point Level Switches

Endress+Hauser Liquipoint T FTW31 Point Level Switches provide simple and safe point level detection in conductive liquids with 10μS/cm minimum conductivity of medium. Depending on the number of measuring points (up to five rods or ropes), tasks such as dry-running protection, overfill protection, two-point pump control, or multiple-point detection can be performed. This cost-effective series easily adapts to varying conductivities, thread-process connections, and two-point control, with additional MAX and MIN detection. No calibration is required, and the tank's lack of moving parts results in a long service life and reliable operation with no wear or blockages. These Endress+Hauser Liquipoint T switches offer IP66 protection and sensor lengths of 0.1m to 4m.
