Capacitive sensor

Capanivo® - CN 7120 - Stainless steel

Application area

The capacitive level limit switch Capanivo® CN 7120 is used as a full, demand or empty detector as well as for leakage detection in all liquid applications. Due to the compact design with 1/2″ process connection the sensor is perfectly suited for use in small vessels and pipes. In addition, the sensor, which has been developed in accordance with EHEDG guidelines, meets increased hygiene requirements. With the IO-Link technology on board, digital data collected by the sensor can be transferred quickly and easily. Moreover the sensitivity can be adjusted directly at the sensor via a potentiometer.
