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

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

Q: How is the set point of the Dwyer EDPS-05-1-N adjusted?

A: The set point can be externally adjusted within the 0.5 to 1.0 in w.c. range using the conveniently located external adjustment knob. This allows for quick and precise setting changes without needing to open the enclosure.

Q: What are the typical applications for this differential pressure switch?

A: Common applications include filter monitoring, fan control, and damper actuation in HVAC systems or industrial environments requiring differential pressure detection in air or compatible gases.

Q: Where should the EDPS-05-1-N be installed for optimal performance?

A: It is designed for panel or surface mounting and should be installed in a location protected from direct water exposure but within the systems airflow or ductwork to accurately measure pressure differentials. Mounting screws are provided for easy installation.

Q: What are the benefits of the manual reset feature in this switch?

A: The manual reset ensures the switch does not automatically return to normal after tripping, providing an additional layer of safety and requiring operator intervention before the system resumes operation. This is crucial for applications with strict safety requirements.

Q: What processes are involved in wiring the EDPS-05-1-N?

A: Wiring is straightforward thanks to screw terminal connections, supporting SPDT snap action with an electrical rating of 5A at 125/250 VAC. Ensure power is disconnected and follow the wiring diagram in the product manual for correct installation.

Q: Which standards and compliances does the EDPS-05-1-N satisfy?

A: This switch is RoHS compliant and CE marked, signifying adherence to rigorous industrial standards for environmental safety and electrical performance.
