DPS33 Differential pressure switch
This differential pressure switch is commonly used in water and oil series to control the pressure difference between the supply and return pipes.
DPS33 Differential Pressure Switch is designed to protect refrigeration compressors and mechanical lubrication systems by maintaining a precise pressure differential between lubricating oil discharge pressure and compressor suction pressure. When the monitored pressure difference falls below the setpoint, the SPDT switch mechanism is triggered to interrupt the compressor circuit, ensuring equipment safety. A standard mounting bracket is included for easy integration.
Key Specifications:
• Core Function: Differential pressure monitoring for compressor and lubrication systems
• Switch Mechanism: SPDT contact design for responsive switching
• Mounting: Standard bracket included for refrigeration unit integration
• Compatibility: Refrigeration compressors, mechanical lubrication systems
Typical Applications:
✔ Lubrication system pressure monitoring
