Pressure switches are critical components in pneumatic, hydraulic, and process control systems. They monitor system pressure and activate or deactivate electrical circuits when preset pressure thresholds are reached. By automating responses to pressure changes, pressure switches help protect equipment, improve system efficiency, and enhance operational safety.
A pressure switch is an electromechanical device that detects pressure changes in a fluid or gas system. When the pressure crosses a predefined limit (either high or low), the switch opens or closes an electrical contact, triggering an alarm, activating a compressor, or shutting down machinery.
Sensing Element: Detects the pressure in the system. This is often a diaphragm, piston, or bourdon tube.
Actuation Mechanism: Moves in response to pressure changes.
Electrical Contacts: Open or close depending on the position of the actuator, controlling the connected electrical circuit.
Use mechanical components to detect pressure.
Simple, reliable, and widely used in industrial applications.
Use sensors and microprocessors to measure pressure.
Offer precise control, display readings, and can integrate with PLCs.
Air Compressors: Start/stop operation based on pressure limits.
Pneumatic Systems: Signal pressure availability or faults.
HVAC Systems: Monitor airflow and refrigerant pressure.
Industrial Equipment: Protect pumps, motors, and actuators from overpressure.
Safety Systems: Automatically shut down systems during abnormal pressure.
