About Dwyer EDPS-05-1-N Adjustable Differential Pressure Switch

Dwyer EDPS-05-1-N Adjustable Differential Pressure Switch

Adjustable differential pressure switch, range .80-4.00" w.c., with M20 connection.

The Series 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 EDPS is available with settings from 0.08" w.c. (20 Pa) up to 16" w.c. (4000 Pa). The silicone diaphragm and PA 6.6 body make the series EDPS ideal for use with air and other noncombustible gases. The compact size, adjustment knob and meeting the UL508 standard make the EDPS the perfect choice for H.V.A.C. applications.

Product Applications

Monitoring air filters and ventilators.
Monitoring industrial cooling-air circuits.
Overheating protection for fan heaters.
Monitoring flows in ventilation ducts.
Controlling air and fire-protection dampers.
Frost protection for heat exchanges

Precision Monitoring for Industrial Environments

The EDPS-05-1-N enables accurate detection of pressure changes in air or compatible non-combustible gas streams, ensuring optimal system performance in demanding industrial or commercial settings. Its wide scale range (0.08 to 1.20 in. w.c.) supports versatile applications such as monitoring air filters, fans, and ducts.

Easy Set-Up and Durable Construction

Engineered with an external adjustment knob and surface or duct mounting options, this switch simplifies installation and reconfiguration. The UL94V-0 flame retardant ABS housing, aluminum cover, and IP54 ingress protection mean lasting durability, even in harsh environments.

Efficient and Accurate Operation

The EDPS-05-1-Ns 15% accuracy, 0.04 in. w.c. (10 Pa) hysteresis, and electromechanical processing ensure reliable switching action. Its SPDT snap switch adapts to a variety of control circuits, creating an effective, responsive monitoring solution.

FAQs of Dwyer EDPS-05-1-N Adjustable Differential Pressure Switch:

Q: How do I adjust the set point on the Dwyer EDPS-05-1-N differential pressure switch?

A: The set point on the EDPS-05-1-N can be adjusted externally using the provided adjustment knob, allowing for easy calibration without disassembly.

Q: What applications is the EDPS-05-1-N best suited for?
