Vacuum Pressure Switches

A vacuum pressure switch operates by comparing the relative pressure between your process pressure and a vacuum. The benefit of this technology is the ability to measure pressure below your local atmospheric pressure. To accomplish this, a vacuum switch has a sealed reference chamber, as well as a diaphragm and a Belleville spring to actuate when your pressure set points are reached.

HVAC, pneumatic, hydraulic or other industries where a setting at atmospheric pressure is desired should consider the Solon Manufacturing Co. vacuum pressure switch series. For processes that cross back and forth between pressure and vacuum, such as HVAC pressure, our vacuum pressure switches provide the ability to have separate vacuum and pressure set points combined in one unit.
