What is a Vacuum Switch?
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.
What are Vacuum Switches used for?
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.
Quick Answers
Frequently Asked Questions
What is the purpose of a vacuum switch?
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.
Can vacuum switches be used with both hydraulic and pneumatic systems?
Yes. Vacuum switches are widely used in hydraulic, pneumatic, and processing industries where monitoring and control of vacuum pressure is required.
What’s the difference between a mechanical and electronic vacuum switch?
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.
How do I know which vacuum range is suitable for my application?
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.
Do Airpower vacuum switches come with both normally open and normally closed contacts?
Yes. Airpower vacuum switches are available with both normally open and normally closed contacts, making them versatile for different control requirements.
