Vacuum Pressure Switches

Vacuum pressure switches are electromechanical devices designed to monitor pressure levels below atmospheric pressure and trigger a switching action when a preset vacuum threshold is reached. These switches typically use a diaphragm or piston mechanism to sense the drop in pressure, activating an electrical contact when the vacuum reaches a defined setpoint. They are available in adjustable or fixed configurations and are commonly used in systems requiring reliable low-pressure monitoring and control.

In industrial applications, vacuum pressure switches serve critical roles in maintaining process safety, protecting equipment, and automating control functions. By monitoring vacuum conditions, they can initiate alarms, engage backup systems, or shut down equipment to prevent damage or system failure due to leaks, over-vacuum conditions, or pump malfunctions. Their high sensitivity and repeatability make them essential in systems where accurate low-pressure control is necessary.

These switches are built to withstand demanding operating environments, featuring corrosion-resistant materials and rugged housings. Many models are available in weatherproof or explosion-proof enclosures for use in hazardous or outdoor settings. Their compact size and mechanical simplicity also make them easy to install and maintain in both new and existing systems.

Typical applications include vacuum pumps, pneumatic conveying systems, leak detection setups, filtration monitoring, and process chambers used in manufacturing, packaging, medical, and semiconductor industries. Vacuum pressure switches enable reliable control and protection in any application where maintaining precise vacuum conditions is essential for performance and safety.
