The Dwyer ADPS Series adjustable differential pressure switches are general-purpose, airflow-proving switches designed for HVAC and building automation applications. The ADPS Series can be used to sense positive, negative, or differential air pressure. The silicone diaphragm and calibration spring are housed in a rugged plastic enclosure with a removable cover protecting the set point adjustment knob and snap action switch terminals. Electrical connections are made through a 7/8 in diameter opening in the cover that accepts a 1/2 in conduit connection. Air sampling connections accept 1/4 in ID tubing.

Differential pressure is defined as the difference in pressure between two given points. It can be measured by using differential pressure sensors to detect increase / decrease of pressure inside a system.
PA 6.6 is a type of polyamide that provides high impact strength, stiffness, low density and high thermal stability.
NEMA 13 enclosure protects against accidental contact with hazardous or sensitive parts and ingress of circulating foreign matter, such as dust, dirt or splashing / dripping water. It also resists the entry of non-corrosive oil and coolant.
The drainable blade type prevents water from accumulating, ensuring effective rainwater management and preventing potential damage caused by water infiltration.
