Dwyer Instruments 1910-00 Pressure Switch 322838-753 000-ohm threshold when the probeThe Dwyer Instruments 1910 0 Pressure Switch is a professional grade differential pressure switch engineered for precision monitoring of air and non combustible gases in HVACR systems. This SPDT switch operates within a precise range of 0. 07" w. c. to 0. 15" w. c., making it an essential component for clogged filter detection, fan proving, and ventilation flow monitoring. With a 0. 04" approximate deadband and a 45" w. c. continuous pressure limit,
