8 DESCRIPTION
The M&C liquid sensor KS2 / KS2.Ex works on the principle of capacitive measurement and is
suitable for non-conductive and conductive media. A pre-amplifier is integrated in the sensor housing
and is connected with the necessary external electronic controller via 2- resp. 3-wire. For the sensor
type KS2 the required electronic controller is available in various versions, FA1.1 or FA1.4 and is
described in a separate data sheet. The M&C liquid sensor KS2.Ex for applications in hazardous
areas and media should only be applied in connection with electronic controller WE77.Ex1, KFA6-
SR2-Ex1.W or an electronic with the same performance data (see chapter 9.4). For electronics with
the same performance data there is no guarantee for problemless operation. The M&C KS2 / KS2.Ex
liquid sensor is constructed in such a way that any droplets of liquid in the sample gas are attracted
directly to the active sensor surface. Even small liquid droplets will trigger a sure and rapid alarm. The
sensors can be mounted with the 16mm

In the event of condensate breakthrough, the filter acts as a buffer vessel preventing immediate liquid
penetration.
