Capacitive sensor

Capanivo® - CN 7150

Application area

The capacitive level limit switch Capanivo® CN 7150 with cable extension is used as a full, demand or empty detector in all kinds of liquids. The cable can be individually configured up to 20 m. The sensor is installed/mounted from the top. Via a user-friendly potentiometer the sensitivity can be adjusted directly at the sensor.
