Gas sampling and conditioning technology 5-5.1.1-ME
7 APPLICATION
Liquid alarm sensors LA 1S and LA 25S 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 simple monitoring device reliably signals the penetration of condensate in the event
of cooling or condensate drain-off equipment being defective and thus avoids expensive down times
as well as high repair costs for analysis instruments.
The electronic controllers LA-1.1 and LA-1.4 are used for feeding and signal processing of the liquid
alarm sensors LA 1S and LA 25S.
In the event of alarm, the power for the sample gas pump or a solenoid valve is to be switched off in
the gas sample conditioning system.
