Air Differential Pressure Switch

An Air Differential Pressure Switch is a device used to sense the difference in pressure between two points in an air system or ductwork. It is commonly used in HVAC (Heating, Ventilation, and Air Conditioning) systems to monitor air pressure and trigger specific actions based on pressure changes. The switch contains a diaphragm or a sensing element that flexes or moves in response to changes in pressure. This diaphragm is connected to an electrical switch mechanism that changes its state (open or closed) based on the pressure difference. Air Differential Pressure Switch can be used to monitor air filter conditions and ensure the correct airflow and pressure levels are maintained.
