Capacitive Level Sensors CPA
Capacitive Level Sensors CPA are building an electrical condenser when being immersed into the liquid. The capacity of the condenser changes with its filling level. An electronic system integrated into the device converts the capacity change into an electrical standard signal 4-20mA proportionally to the filling level. Calibration 0% and 100% is made at keypress (TEACH IN). Capacitive Level Sensors CPA will be programmed by the factory if required by the customer (0% and 100% marker can be set if required by the customer).
