FAQs
What is an air pressure switch and how does it work?
An air pressure switch is a device that monitors and controls the air pressure in a system, typically used in applications such as air compressors, pneumatic systems, and HVAC systems. It works by sensing the air pressure and sending an electrical signal to a control device, such as a relay or a controller, when the pressure reaches a predetermined setpoint. This signal can then be used to turn on or off a device, such as a compressor or a valve, to maintain the desired air pressure.
The air pressure switch typically consists of a sensing element, such as a diaphragm or a piston, that moves in response to changes in air pressure. This movement is then translated into an electrical signal, which is sent to the control device. The setpoint of the air pressure switch can be adjusted to suit the specific requirements of the application, and some switches also have additional features such as differential pressure settings and adjustable hysteresis. With an air pressure switch, system operators can ensure that their equipment operates within a safe and efficient pressure range, reducing the risk of damage, downtime, and energy waste.
