Setpoints from 10" w.c. to 200 psid – Rated 1500 psig, Weatherproof. Explosion-proof Series H3 Explosion-Proof Differential Pressure Switch, heavy duty, industrial unit has a unique new

Sensors for air and non-combustible compatible gases have an electrical contact output at a specific difference between two pressures. Applications vary between the different types of differential pressure switches. A wide variety of switches and circuit styles enables control functions needed for any system.

In this cooling application, the Dwyer differential pressure switch senses the increasing restriction to air flow caused by icing and actuates the defrost cycle. Two static tips are installed to sense the differential pressure across the cooling coils. Pressure switch monitors flow in high pressure system.

The Dwyer Model 1900-5-MR manual reset pressure switch is designed to monitor duct static and shut down the blower when excess pressure occurs. The switch must be manually reset before the system can start again. Switch contacts are SPDT with solder-type connections. The Model 1900-5-MR measures static pressure only, not differential pressure.

Our most popular Series 1900 Compact Low Differential Pressure Switch Set point adjustment is easy with range screw located inside conduit enclosure.
