Pressure switches are electronic instruments which control changes in pressure. They sense a rise or decrease in pressure and can regulate this pressure accordingly. In most cases, they sound an alarm or shut of a system. Pressure switches are used in numerous environments like the manufacturing, utility plants and commercial establishments. Most pressure switches operate automatically.
Applications in devices
Devices that use pressure while in operation, generally need pressure switches. This pressure can be in the form of electricity, gas, steam or liquid. The accepted level of pressure varies between different devices. If the level increases, pressure switches sound an alarm or stop the process automatically.
Pressure switches have helped reduce accidents
Since their invention, pressure switches have considerably reduced the number of accidents in industry. There have been numerous instances where pressure switches have avoided mishaps. Many factories and utility plants use pressure switches in their devices as a safety precaution. In case there is a variation in pressure, the switch sounds an alarm. In the case of automatic pressure switches, valves can be shut or the process halted automatically.
