1800 Low Differential Pressure Switch for General Indust...
Small size and low price with 2% repeatability, wide range of models from 0.07 in W.C. - 85 in W.C.
Essential for industrial environments, the Series 1800 combines small size and low price with 2% repeatability for enough accuracy for all but the most demanding applications. Set point adjustment inside the mounting stud permits mounting 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.
Please see Series AT21823 for ATEX approval.
