High-precision CPDS (Compressor Discharge Temperature Sensor) thermistor engineered for Carrier reefer containers. This device continuously monitors the compressor's discharge temperature and transmits real-time data to the central controller. It effectively prevents critical system overheating, optimizes operating cycles, and protects the compressor unit from premature wear. The sensor is built to withstand high thermal stress, continuous vibrations, and exposure to refrigerants.
