2CP5-71-39 Low Pressure Transducer | Carrier Screw Chiller Suction Pressure Sensor

The 2CP5-71-39 is a precision refrigerant pressure transducer engineered for Carrier screw chiller and compressor systems, tasked with real-time monitoring of the low-pressure suction side of the refrigeration circuit.
This sensor converts refrigerant suction pressure into a proportional electrical signal, delivering accurate pressure feedback to the chiller’s main control board. This data is critical for maintaining stable system operation, preventing underpressure or vacuum conditions, optimizing compressor performance under variable load conditions, and protecting against liquid slugging or component failure.
Constructed with a stainless steel pressure-sensing element, a hermetically sealed refrigerant passage, and a robust brass housing, it is designed to resist refrigerant corrosion, system vibration, and the harsh operating conditions of industrial HVAC systems. The integrated electrical connector ensures reliable signal transmission in demanding environments.
This is a direct OEM replacement part, fully compatible with Carrier screw compressor and chiller control systems.
Core Functions:
Monitor compressor suction low pressure
Provide proportional electrical signal feedback to the main control board
Prevent underpressure, vacuum conditions, and abnormal system shutdown
Optimize compressor efficiency and protect critical components
Application:
Carrier screw chiller & compressor low-pressure control loop.
