Capacitive sensor
Capanivo® - CN 7121 - Synthetic
Application area
The capacitive level limit switch Capanivo® CN 7121 is used as a full, demand or empty detector as well as for leakage detection in all liquid applications. Made entirely of durable, chemical resistant plastic materials, the sensor is ideal for aggressive media. Even measurement from outside the vessel without direct material contact is possible. Thanks to the innovative IO-Link electronics, sensor data can be digitally transmitted quickly and easily. The sensitivity is adjusted in a user-friendly way via a potentiometer directly at the sensor.
