Endress+Hauser Liquifloat FTS20 Point Level Switches
Endress+Hauser Liquifloat FTS20 Point Level Switches offer a simple and cost-effective solution for point level detection in appropriate fluids. The FTS20 series is designed for use as a pump protector or overfill prevention device in tanks and vessels and as a level alarm in open basins, such as sewage treatment plants. These float switches include two output options: a NAMUR switching signal for hazardous areas and a change-over contact for universal standard applications. Additional benefits include +3bar (+43.5psi) pressure, IP68 ingress protection, and simple installation using a tapped G1A hole. Endress+Hauser Liquifloat FTS20 Point Level Switches feature international explosion protection certificates.
