6 INTRODUCTION
The M&C liquid alarm units series LA
®
are designed for stationary continuous operation and when
installed properly guarantee a long service life and a minimum of maintenance work.
7 APPLICATION
Liquid alarm sensors LA1S and LA25S 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 straightforward monitoring device reliably signals the condensate ingress 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 LA1.1 and LA1.4 are used for feeding and signal processing of the liquid
alarm sensors LA1S and LA25S.
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.
