Vacuum Switches

Vacuum switches are either electronic or mechanical devices used in pneumatic systems to control the flow of pressure or vacuum between locations, helping to maintain system stability. These switches are widely employed for pressure regulation and safety interlock functions, ensuring optimal operating conditions are preserved.

By regulating vacuum flow between two areas, vacuum switches guarantee that the necessary vacuum is maintained where required. They operate under various pressure types, including negative, electro-mechanical, relative, or compound pressure. The specific operating conditions of your system will guide the selection of the appropriate switch.

Vacuum pressure switches are designed to detect changes in vacuum pressure. A preset threshold is established, and once this level is reached or exceeded, the switch will either open or close its electrical circuit.

Types of pressure and vacuum switches

These switches function under different pressure categories, such as negative pressure, electro-mechanical pressure, relative pressure, and compound pressure. The operating environment influences the type selected. Additionally, they vary in connection types, pressure range limits, and voltage drop specifications.

Digital hydraulic pressure switches are sensors that respond to fluid pressure changes. They activate or deactivate electrical contacts when preset fluid pressure values are reached, responding to either increasing or decreasing pressures.

What are digital hydraulic pressure switches used for?

Digital hydraulic pressure switches serve as automatic monitoring devices in systems with pressurized fluids. They are commonly used in manufacturing to provide feedback on pressure spikes or drops. In mobile industrial equipment, these switches display oil pressure numerically and trigger alarms if engine pressure falls outside safe limits.

Applications:

Vacuum switches are utilized across various industrial settings, playing a critical role in monitoring and control within hydraulic and processing industries. These switches detect vacuum changes and open or close electrical circuits once preset points are reached, ensuring reliable system operation.
