6.2.3 Splash-Guard & TGA-1
General Monitors produces a universal Splash-Guard, P/N 10395-1, that has been
designed for use on all General Monitor's combustible gas and hydrogen sulfide gas
sensors (Figure 66). In addition to the Splash-Guard, a Test Gas Applicator (TGA-1) is
available for delivering a test gas to remotely located sensors, P/N 10460-2.
The Splash-Guard prevents water from rain or equipment wash-downs from being
forced into the sensor cavity and affecting the response of the sensing element.
Constructed of rugged Valox plastic, it has a series of internal baffles to deflect water
down and away from the sensor. This guard (and the TGA-1) is threaded for simple
screw-on installation. The Splash-Guard and TGA-1 are recommended for outside
applications where rain or frequent hose downs occur, such as offshore platforms.
