A pressure switch, in its simplest form, is a device which is capable of detecting a pressure change and, at a decided level, opening or closing an electrical contact. Pressure switches fall into three basic classifications: solid state, electromechanical, and electronic. Pressure switches have been electromechanical devices traditionally. However, today, inroads into this old technology are being made by solid-state devices and the new type of electronic pressure switches.
Electromechanical Pressure Switches
The most common electromechanical pressure switches are made of a sensing element and an electrical snap-action switch. Many different types of sensing elements can be used, but they have one thing in common, which is that they move in response to the changes taking place in the system pressure.
Solid-State Pressure Switches
Back when solid-state pressure switches were introduced, they were a simple device which combined a triac switch and bonded strain gage sensor. At present, there are a wide range of solid-state pressure switches having one to four or more switch points, analog and digital outputs, digital displays, and full programmability. You could buy these switches from Switzer Pressure Switches.
Around two decades after pioneering the solid-state pressure switch the next game-changer, the BPS3000 Electronic Dual Pressure Switch has been introduced. This digital pressure switch represents the next step in the pressure switch evolution and features some very impressive attributes.
