Capacitive sensor

Capanivo® - CN 4020

Application area

The capacitive point level sensor Capanivo® CN 4020 is used in storage and process vessels as a full, demand, and empty detector in all bulk solids from a DK value of 1.6. The probe made of glass fiber reinforced PPS plastic is FDA compliant and also suitable to be used in food. Due to its “Active Shield” function any buildup does not in any way affect the accuracy of the measurement results of the sensor.
