Description :

The RSF20 is designed to eliminate the problems associated with limescale build up around the pivot point on a conventional float switch.

This particular series is primarily for applications where a low level condition has to be monitored, in a system where the liquid is usually maintained at a high-level, or where a wider differential is required between the opening and closing levels.

The extended drop float actuator allows the switch housing and float pivots to be located above the surface of the liquid, while the excess buoyancy of the float chamber itself ensures that it floats, even when scale builds up on the float chamber.

Typical applications include wall kettles and hot vending machines.

The switch is closed when the level is low (float down) and opens as the liquid level rises.
