This pressure switch is designed for use in ventilation and air conditioning systems to monitor and control air flow in ducts, as well as in filters, dampers, and fans. It is suitable for use with air and other non-corrosive, non-aggressive gases. The switch detects small pressure changes and is widely used for controlling air flow, monitoring fans, and HVAC applications. It can also be used for overheat protection and frost protection in industrial refrigeration systems. The adjustable set point allows for visual calibration due to its design.
