Description

Series 1800 Low Differential Pressure Switch for General Industrial Service

Set Points from 0.07″ to 85″ w.c. Repetitive Accuracy within 2%

Essential for industrial environments, the Series 1800 Low Differential Pressure Switch for general industrial service combines small size and low price with 2% repeatability for all but the most demanding applications. Set point adjustment inside the mounting stud permits mounting the switch on one side of a wall or panel with adjustment easily accessible on the opposite side. UL and CSA listed, and FM approved.

CAUTION: FOR USE ONLY WITH AIR OR COMPATIBLE GASES.

 

Product Applications

  • Process applications
