Applications of Pressure Switches

Pump Control
To maintain the pressure within specified limits by controlling the operation of pumps. For example, in water pumping systems, pressure switches ensure that the system maintains adequate water pressure.

Safety and Alarm Systems
To prevent overpressure conditions that could lead to equipment failure or safety hazards. Pressure switches can activate safety valves or alarms to alert personnel.

HVAC Systems
To regulate pressures within heating, ventilation, and air conditioning systems, ensuring efficient operation and preventing pressure extremes.

Compressed Air Systems
To control the air pressure in compressors and pneumatic systems, activating or deactivating the compressor as needed to maintain the desired pressure level.

Hydraulic Systems
To monitor and control the pressure in hydraulic circuits used in machinery and manufacturing processes.

Refrigeration Systems
To detect and control the pressure of refrigerants, helping to manage the cycling of refrigeration compressors.
