Application
Liquid alarm sensors are used in gas sample conditioning systems for monitoring gas
cooling and condensate drain-off devices in
order to provide protection for downstream
analysis instruments. This monitoring device
KS 2/KS 2.Ex reliably signals the penetration
of non conductive (e.g. alcohol) and conductive (e.g. water) liquid in the event of cooling
or condensate drain-off equipment being
defective, thus avoiding expensive down time
as well as high repair costs for analysis instruments.
In the event of an alarm, power for the sample
gas pump must be switched off or a solenoid valve must be switched idle in the sample conditioning system.

Description
The M&C liquid sensor KS 2/KS 2.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 KS 2 the required electronic controller is available in various versions,
FA1.1; FA1.4 and is described in the separate
data sheet 9.5.
The M&C liquid sensor KS 2.Ex for use in
hazardous areas and media should only be
applied in connection with electronic controller WE77.Ex1 or KFA6-SR2-Ex1W.
The M&C KS 2/KS 2.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 the smallest
liquid droplets will trigger a sure and rapid
alarm.
The sensors are mounted with the 16mm ø
stainless steel body in the GL-25 connector
of the universal filter F..-..-D or the condensate
pot TG1 or in the flow chamber LS/KS.
