Air Pressure Sensors & Switches
Air pressure sensors and switches monitor and react to changes in air pressure within an HVAC system. Differential air pressure sensors tap into two points of the HVAC system and measure the pressure difference between them. Air pressure sensing switches measure the air pressure inside the HVAC system and make or break an electrical connection based on their setpoint. Air pressure sensing probes are installed into HVAC ducts and measure the air pressure inside.
