Normally open and normally closed contacts.
These units can run two vacuum pumps in a lead lag configuration.
Also suitable to monitor vacuum at the point of use.
-1 to +1 bar range. Will withstand a pressure of 3 bar.
Power supply 12 to 24 Volt DC. Current consumption is less than 55 mA.
A vacuum switch is an electronic or mechanical device that provides an electrical switching contact function at a defined vacuum gas pressure level. It’s used in many vacuum applications for pressure control purposes and safety interlock functionality.
Vacuum switches are an essential component for many monitoring and control applications in hydraulic, pneumatic and processing industries. Performing in critical processes, these switches sense a change in the vacuum and open or close an electrical circuit when the chosen setpoint is reached.
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 setpoints are reached.
A vacuum switch is designed to monitor and control vacuum levels in a system. It opens or closes an electrical circuit when a set vacuum pressure is reached, providing safety interlocks and reliable process control.
Yes. Vacuum switches are widely used in hydraulic, pneumatic, and processing industries where monitoring and control of vacuum pressure is required.
A mechanical vacuum switch uses a diaphragm and spring mechanism to trigger switching, while an electronic vacuum switch uses sensors and circuits. Mechanical switches are simple and durable, while electronic versions offer higher accuracy and digital integration.
The correct range depends on your system’s operating vacuum pressure. Airpower offers switches with ranges from –1 to +1 bar, ensuring compatibility with most industrial applications.
Yes. Airpower vacuum switches are available with both normally open and normally closed contacts, making them versatile for different control requirements.
We are fully equipped to handle major overhauls, pressure testing, and component sales directly from our Bellville headquarters.
