Description
ALM level sensors are used to measure and transmit the level of liquids in conjunction with a customer’s control unit outside of the containment area. It is based on the float principle with magnetic transmission in a 3-wire potentiometer circuit.
The resistance measuring chain is closely stepped. Due to this assembly the generated voltage is approximately continuous. Signal transmission over large distances and use in hazardous areas are possible.
