Dwyer Instruments ADPS-03-2-N Pressure Switch
The Dwyer ADPS-03-2-N is a field-adjustable differential pressure switch engineered for monitoring overpressure, vacuum, and differential pressure in HVAC and building automation systems. This specific model features a setpoint range of 0.08 to 0.8 in w.c. (20 to 200 Pa), making it ideal for clogged filter detection and fan proving applications. Utilizing a silicone diaphragm and a rugged PA 6.6 plastic housing, the unit ensures reliable switching in non-combustible gas environments. The SPDT switch configuration allows for versatile wiring as a normally open or normally closed contact, handling up to 1.5A inductive loads. Designed for vertical mounting, the ADPS-03-2-N includes a dual-scaled adjustment knob for precise field calibration without the immediate need for a separate pressure gauge. Its IP54 rating and compact footprint make it a staple for contractors necessitating a durable air pressure sensing solution in commercial air handling units and ventilation systems.
- Easily Adjustable Setpoints: The integrated adjustment knob features a dual-scale (inches w.c. and Pascals) for rapid field tuning to system pressure requirements.
- High Reliability: The silicone diaphragm and 10^6 switching cycle rating provide long-term stability in HVAC pressure monitoring.
- Flexible Installation: Compact design with barbed pressure connections simplifies integration into existing ductwork and control panels.
- Versatile Signaling: SPDT contact logic supports simultaneous alarm signaling and equipment interlocks for differential pressure control.
Common Technical Questions
What is the maximum pressure rating for this switch?
The ADPS-03-2-N is rated for a maximum operating pressure of 40 inches w.c. (10 kPa). Exceeding this limit can cause permanent deformation of the internal silicone diaphragm.
Can this unit be mounted horizontally?
The manufacturer specifies vertical mounting for the ADPS series. Mounting horizontally will shift the switching point due to the weight of the diaphragm, affecting accuracy at the lower end of the pressure range.
Is this switch suitable for outdoor air applications?
While the switch features an IP54-rated cover, it should be protected from direct water ingress and extreme UV exposure. It is intended for use with non-corrosive, non-combustible gases.
