The Series ADPS/EDPS Adjustable Differential Pressure Switch is designed for pressure, vacuum, and differential pressures. The dual scaled adjustment knob in inches water column and pascals allows changes to the switching pressure to be made without a pressure gage.

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

This category contains a variety of Dwyer Differential Pressure Switches. Sensors for air and non-combustible compatible gases have an electrical contact output at a specific difference between two pressures.

Adjustable Set Point, High Overpressure Differential Pressure Switch which is capable of carrying moderate shock and vibratory loads. Piston design allows mounting in any orientation. Offers field adjustments and can handle system pressures up to 6000 psig. , Series PDPS,

Dwyer 1900-5-MR Compact Low Differential Pressure Switch, Manual Reset, Range 1.4 - 5.5" W.C. The Dwyer 1900-5-MR Compact Low Differential Pressure Switch 

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

Dwyer's 1831 DPDT low differential pressure switches with manual reset eliminate common problems associated with typical high duct static cutout installations. Using an 1831 reduces both material and labor installation costs. Because the 1831 doesn't require power to drive its outputs, there's no need for a separate power loop or its associated
