Description

FLOAT LEVEL SWITCH SERIES SSW71

Inside the float is placed a magnet which drives, without contact, reed contacts located inside a pipe that can itself be the guide of the float. Moving along its guide pipe, the float changes the reed contact status. These variations are then acquired and processed by the electronic board.
Thermal drift is compensated using the temperature signal generated by a PTC thermistor integrated in the sensor itself. Based on these readings the microprocessor generates a standard ON/OFF signal output, shows the measurement on the display and command a contact depending by a set threshold.
