Function:
For watching and controling the filling levels
in reservoirs containing heavily polluted
liquids with or without metallic abrasions.
Beneath the reservoir's cap there is a float
in the liquid. The switching contacts and the
switching magnet are situated above the
reservoir's cap. The float is connected with
the magnet via a pipe. Hence the movements of the float are transmitted into the
upper part of the level switch.
The moving range of the float is limited by
means of four differential measure areas.
The switching points need to be arranged
within the differential measures.
On a hole strip having very small differential
spaces, 3 switching contacts can be positioned at maximum. The contacts can be
shifted in a 10 mm grid. Their switching
behaviour is bistable. When the float exceeds the switching point, the switching
function will continue to be available. The
switching functions "opener" or "closer" can
be changed by turning the contac
