dwyer differential pressure switch manual

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

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.

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.

The 1950G is very compact, about half the weight and bulk of equivalent conventional explosion-proof switches. Easy access to the SPDT relay and power supply terminals is provided by removing the top plate of the aluminum housing. A supply voltage of 24 VDC, 120 or 240 VAC is required.

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.
