A gauge-vacuum crossover pressure switch combines the best of both worlds, putting both vacuum pressure and gauge pressure control at your fingertips. It 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, or in other words, to measure negative 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.

These certified adjustable electrical switches are a perfect fit for general purpose areas or can be designed to be explosion proof for hazardous locations. Whether it is well pump and compressor pressure control or filter and level monitoring to high static pressure control, these switches are suited to any number of industrial applications. There are many options available through our configurator such as Hazardous area approvals, the output format of your switch, the wetted materials, and more. Use the filter and compare feature to find the switch for you!
