Differential Pressure Switches


The 1910 Series differential pressure switches are designed to monitor the differential pressure of air in HVAC applications and building automation systems, BAS. An automatic reset pressure switch is available in ranges from 0.07" to 20" W.C. (17.4 to 4982.0 Pa) with SPDT screw type electrical connections. The optional Model A-602 air filter kit includes two static pressure tips, aluminum tubing, and fittings, and it allows the 1910 Series to monitor filter pressure drop.
