low level switch for
boiling water
RSF20
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 remains buoyant, even when
scale builds up on the float chamber. Typical
applications include wall kettles and hot
vending machines.
The switch action is closed when the level is
low (float down), and opens as the liquid level
rises.
