Description:

      The  pressure differential  alarm package  continually  monitors  and  displays  the strainer’s  inlet and  outlet  differential 

pressure.  When the strainer element (conical strainer basket) becomes significantly clogged, the pressure differential switch-gauge 

will  trigger  an  audible siren  and  a  visual  flashing  alarm  light.    These  alarms are intended  to  alert  maintenance  personnel  that  the 

strainer element must be removed and cleaned (see your 

Thompson Strainer Owner

’

s Manual

 for complete strainer element cleaning 

instructions).
