What is a Pressure Switch? Its Working, Types, and Selection
Again, depending on the pressure handling capability, there are two types of pressure switches; High-pressure switches and Low-pressure switches. High-pressure switches are designed to operate from 1 PSIG to 10, 000 PSIG whereas low-pressure switches can respond to small pressure fluctuations.
Pressure Switch Explained - Tameson.com
2020年6月10日 · Pressure: The pressure switch must be able to withstand the maximum working pressure. Low pressure switches typically use a diaphragm as the sensing element, while high-pressure switches use a piston design. Temperature: The pressure switch's temperature range must include the application's minimum and maximum temperatures. High temperature ...
Pressure Switch - Types, Applications, and How they Work
Negative pressure systems require pressure switches specified for vacuum and compound pressure. Diaphragms are ideal for vacuum and low-pressure applications. Pistons are ideal for high-pressure applications.

The “PSH” (pressure switch, high) activates when the air pressure inside the vessel reaches its high control point. The “PSL” (pressure switch, low) activates when the air pressure inside the vessel drops down to its low control point. Both switches feed discrete (on/off) electrical signals to a logic control device (symbolized by the ...
