Digital pressure switches are mainly based on electronic pressure transmitters. This provides the switch with the complete functionality of a transmitter. Simple control tasks can be performed using the integrated pressure switch. The switching points can be set individually using the digital display or an I/O link. A pressure switch can be used in a wide range of domestic and commercial applications as listed below: To monitor and control the system air pressure, HVAC, gas cylinders, air pumps, etc. utilize air compressor pressure switches.
Pressure switches rely on water pressure to do all the work. The change in pressure that activates the switch is provided via the water from the well. The pressure moves up through the diaphragm which presses against a piston and spring, which in turn opens or closes the contacts. Pressure switches fall under three basic classifications: electromechanical, solid state and electronic. Digital pressure gauges measure the pressure within a system in a special manner. They convert the pressure to an electronic signal.
The gauge shows the pressure using a digital display, furthermore the signal can be used to control equipment. Digital gauges in comparison with analog ones have a higher accuracy. A pressure rise will cause the switch to open. This would typically be applied as a high-pressure switch. If the pressure gets too high, the switch will open and shuts off the pump that is adding pressure to the system.
