More informations

The level switch of the model type series FS11 operates acc. to float principle with magnetic transmission. The sensor consists of a guide tube with embedded Reed contacts, one or more floats with fitted ring magnets and a process connection module. The float is raised by the rising liquid in the tank and operates a Reed contact through the guide tube wall by means of the magnetic field produced by permanent magnets located in the float. The Reed contact can be designed as a NO, NC or SMDT function.

Typical applications

The FS11 magnetic float level sensors are suitable for monitoring the level practically all liquids, e.g. as a full or empty tank sensor, for controlling valves and pumps and for alarm function. The potential free Reed contacts fitted in the level sensor make it an ideal control element when coupled with PLC controllers.
