With the LI level sensor, you can reliably detect leakages and point levels on a permanent basis. The capacitive measuring system has no moving parts. Malfunction or maintenance issues due to deposits on the mechanical parts are therefore eliminated. Thanks to the WHG approval, you can also comply with the legal requirements for substances that are hazardous in water.
Easy set-up, digital communication
The sensors are factory-set for specific media (LI21xx: oils, LI51xx: aqueous media), so they can be easily put into operation via plug and play. Thanks to the teach button and IO-Link, they can be adjusted to other media just as easily. Another advantage is that the sensors also detect the temperature of the medium. This is transmitted via IO-Link, but can also be assigned to one of the two switching outputs.
These sensors are used in applications with coolants, cleaning agents and lubricants, and hydraulic oils.
