Air Compressor Pressure Sensor Applications
Air Compressor Pressure Sensors are pressure-sensitive electrical
sensing devices used to control the operation of an air compressor.
The main function of the sensor is to start the Air Compressor when the pressure in its holding tank drops below a set low point
and to stop it when the pressure reaches a set maximum. This allows
the compressor to maintain a constant working charge in the system,
an essential criteria for industries that are heavily reliant on
compressed air. The Air Compressor pressure sensor is typically mounted on the compressor assembly or
in another easily accessible location, with the Air Compressor control circuit wired through its internal contacts.
Description of air compressor pressure sensors
Typically, an Air Compressor pressure sensor is used to measure the pressure of fluids (gases or
liquids). Pressure is an expression of the force required to stop a
fluid from expanding, and is usually stated in terms of force per
unit area. A pressure sensor generates an electrical signal
relating to the pressure imposed. Such a signal is normally digital
or analogue, although optical, visual and auditory signals are also
common.
