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.

In the event of condensate penetration, the lter housing acts as a buer vessel
