Our capacitive liquid sensor offers precise and reliable level measurement of liquids directly on the medium. Developed as a replacement for mechanical sensors, it enables accurate monitoring of a wide range of liquids in various applications.


Sensor type:

The sensor is specially designed for the wetted level measurement of liquids. It has a specially shaped tip that ensures optimised dripping of the liquids. The sensor is already preset for use with distilled water. The switching threshold can be easily adapted to other liquids using a potentiometer.

Output configuration:

The sensor offers flexible output options, including NPN or PNP configuration as well as normally open or normally closed (NO/NC).


It is supplied with a 2 metre cable that has open cable ends with ferrules. This ensures easy installation.
