About Dwyer EDPS-03-1-N Adjustable Differential Pressure Switch

Dwyer EDPS-03-1-N Adjustable Differential Pressure Switch

Adjustable differential pressure switch, range .20-2.00" 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

The adjustable setpoint via the user-friendly knob allows you to calibrate the switch easily for different monitoring needs. This makes the switch efficient for applications from filter monitoring to duct pressure supervision.

Durable and Easy to Install

Constructed with high impact polycarbonate and featuring IP54 ingress protection, the EDPS-03-1-N is engineered for demanding industrial environments. Its lightweight build and surface mount design, complemented by included mounting screws, ensures hassle-free installation for both new and existing systems.

FAQs of Dwyer EDPS-03-1-N Adjustable Differential Pressure Switch:

Q: How does the setpoint adjustment work on the Dwyer EDPS-03-1-N?

A: The setpoint can be precisely adjusted using the integrated knob on the device. This allows users to calibrate the switch for a differential pressure range between 0.12 and 3.0 in w.c. (30 to 747 Pa), making it suitable for various system requirements.

Q: What types of media are compatible with this differential pressure switch?

A: The EDPS-03-1-N is designed to measure the pressure of air and non-aggressive, non-combustible gases. It is not suitable for liquids, aggressive chemicals, or combustible gases.

Q: When should this pressure switch be used in an HVAC system?

A: This switch is ideal for continuous monitoring of filters, air ducts, fans, and cleanrooms to activate alarms or controls if preset pressure differences are detected, indicating potential issues such as filter clogging or ventilation failures.

Q: Where can the Dwyer EDPS-03-1-N be installed?

A: The unit is suitable for surface mounting on walls, panels, or ducts. With two internal 1/8 NPT ports, it can be connected to different monitoring points in your air distribution or ventilation system.

Q: What benefits does the EDPS-03-1-N offer compared to fixed pressure switches?

A: With its adjustable setpoint and wide range, the switch provides flexibility across different applications. Its high accuracy, robust housing, and ease of installation make it a reliable choice for industrial and commercial sites seeking effective pressure control solutions.

Q: What is the process for installing the EDPS-03-1-N switch?

A: Installation involves securely mounting the switch using the provided screws, connecting the pressure lines to the NPT ports, and wiring it according to the instruction manual. Its compact size and surface mount capability streamline the integration process.

Q: Can the EDPS-03-1-N be used outdoors?

A: While the switch features IP54-rated ingress protection, it is primarily designed for indoor environments or sheltered locations. If outdoor installation is necessary, additional weather protection may be required.
