Air Pressure Sensing Switches
Available70 products
Air pressure sensing switches are installed into HVAC ducts and pipes, detect air pressure changes, and trigger actions when pressures reach the designated setpoints. They can respond to positive or negative pressure or a differential between two points. They monitor the air pressure at critical points in the HVAC system and regulate fans, dampers, and other components that affect airflow.

They are commonly used for OEM (original equipment manufacturer) applications where equipment settings are optimized by the manufacturer.
