THERMISTOR CDT (MRD-12-00284-00)

The thermistor CDT (Compressor Discharge Thermistor or sometimes Cabin Discharge Thermistor) is a critical sensor used in transport refrigeration systems to monitor temperature. Its readings help maintain proper system operation, protect components, and ensure efficient temperature control.

• Temperature Monitoring: The thermistor CDT measures the temperature of either the compressor discharge line or the air leaving the evaporator, depending on system design.
• Component Protection: If discharge temperatures rise too high, the system can intervene to prevent compressor damage or unsafe operating conditions.
• Control Feedback: Temperature readings are sent to the controller, which adjusts system behavior (such as compressor cycling or fan speed) to maintain desired cooling performance.
• System Diagnostics: The thermistor provides valuable data for troubleshooting system issues like overheating, refrigerant loss, or airflow problems.

In summary, the thermistor CDT plays a vital role in transport refrigeration by providing real-time temperature data that helps regulate, protect, and optimize system performance.
