35CP02-04 Refrigerant Pressure Sensor For Trane HVAC Units

35CP02-04 is a commonly used refrigerant pressure sensor for Trane commercial and data center air conditioning units. The original product is the 35CP series ceramic capacitive product from Sensata. It features brass liquid contact, sealed gauge pressure measurement, 5V power supply output ranging from 0.5 to 4.5V proportional voltage, and can be directly connected to the main control board. It is used to monitor system pressure in real time, providing signals for compressor regulation and high-pressure protection. The ceramic core is resistant to refrigerant corrosion and has low temperature drift. Combined with IP65 protection and overvoltage reverse connection protection, it can still output stably in a range of -30 to 100°C and under strong vibration conditions. It is a maintenance replacement part. When selecting, it is necessary to check the original machine's range, threads and connectors. For upgrading and replacement, reference can be made to 45CP2-7.
