Dwyer Instruments EDPS-08-2-N Pressure Switch
The Dwyer Instruments EDPS-08-2-N Pressure Switch is a professional-grade differential pressure switch designed for HVAC airflow proving applications. Engineered with a setpoint range of 0.08 to 1.20" w.c. (20 to 300 Pa), this unit provides reliable monitoring for air filters, ventilators, and industrial cooling circuits. The EDPS-08-2-N utilizes a sensitive silicone diaphragm and a PA 6.6 body to ensure precise actuation even at low pressures. Its SPDT switch configuration allows for flexible integration into DDC systems, either for normally open or normally closed control logic. Featuring an M20 connection for secure electrical entry and a rugged NEMA 3 enclosure (IP54), this switch is built for demanding environments. For optimal accuracy and to prevent condensate accumulation on the internal diaphragm, the device must be installed in a vertical mounting orientation with the pressure ports directed downward. This series is compatible with air and other non-combustible gases, making it a standard choice for duct static pressure monitoring and frost protection in heat exchangers.
Key Benefits- Field Adjustable Setpoint: Integrated adjustment knob with dual-scale (in w.c. and Pascals) allows for precise calibration without an external pressure gauge.
- Versatile Compatibility: Designed for use with air and non-combustible gases across commercial HVAC differential pressure switch applications.
- Rugged Construction: Features a plenum-rated plastic housing and a high-durability silicone diaphragm capable of over 10^6 switching operations.
- Industry Compliance: Meets UL508 and CSA C22.2 No. 14 standards, ensuring safety and performance in building automation systems.
How do I ensure the most accurate pressure reading during installation?
To maintain the stated sensitivity of the EDPS-08-w-N, always mount the switch vertically. This prevents the weight of the diaphragm from shifting the setpoint and ensures that moisture or particulate does not settle on the sensing element.
Can the EDPS-08-2-N be used in outdoor applications?
The unit features a NEMA 3 enclosure and IP54 rating, providing protection against dust and splashing water. While suitable for many sheltered environments, verify that the ambient temperature remains between -4°F and 140°F during operation.
Is an orifice or static tip required for duct mounting?
Yes, for accurate air velocity or static pressure sensing in ductwork, we recommend using the Dwyer A-481 installer kit or equivalent static pressure tips to ensure a clean signal to the 1/4" ID process connections.
