Dwyer Instruments ADPS-08-1-N Pressure Switch
The Dwyer Instruments ADPS-08-1-N is a field-adjustable differential pressure switch designed for critical airflow monitoring and proving applications in commercial HVAC and building automation systems. Built with a robust silicone diaphragm and a PA 6.6 body, this switch monitors air and non-combustible gases with a set point range of 0.08 to 1.20 inches w.c. (20 to 300 Pa). Featuring an integrated SPDT relay contact, the ADPS-08-1-N allows for seamless integration into DDC systems for filter monitoring, fan status detection, and frost protection. The calibrated adjustment knob eliminates the need for an external pressure gauge during setup, while the 1/2 inch NPT conduit connection and push-on screw terminals simplify field wiring. This HVAC airflow proving switch is rated for temperatures from -4 to 185°F and carries an IP54 / NEMA 3 enclosure rating, ensuring reliable performance in demanding mechanical environments when mounted vertically with downward-pointing ports.
Key Benefits- Field-Adjustable Precision: Dual-scaled knob allows for rapid set point changes without requiring specialized calibration tools.
- Versatile Control Logic: SPDT output provides flexibility for normally open or normally closed wiring configurations.
- Enhanced Durability: Mechanical life exceeding 1,000,000 cycles for long-term installation stability.
- Reliable Sensing: Sensitive silicone diaphragm detects minute pressure differentials as low as 0.08" w.c.
What is the maximum operating pressure for this switch?
The ADPS-08-1-N is rated for a maximum operating pressure of 40 inches w.c. (10 kPa) across its entire adjustment range.
Can this pressure switch be mounted horizontally?
While vertical mounting is recommended for accuracy, horizontal installation is possible if no condensate is present; however, the switching point will increase by approximately 0.08" w.c.
Which tubing size is compatible with the process connections?
The unit accepts standard 1/4 inch (6.0 mm) inside diameter or 5/16 inch (7.94 mm) outside diameter flexible tubing.
