1800 Low Differential Pressure Switch, Working Pressure : 10 Psig (68.95 kPa) Continuous, 25 Psig (172.4 kPa) Surge.

1800 low differential pressure switch

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.
