Sensors are key components for temperature and pressure detection and operation regulation of cold storage refrigeration systems. Their working accuracy is directly related to the stability of system operation. Sensor aging and failure, as well as data errors, are core hidden dangers that are easy to be ignored but have far-reaching impacts.

         Sensor aging and failure are mostly caused by long-term outdoor environment erosion, component loss or untimely maintenance, which will lead to failure of detection function and inability to feedback real operation data; data errors will mislead system regulation, cause refrigeration abnormalities, increase energy consumption, and even accelerate the wear of core equipment.

         It is necessary to regularly check the operating status of sensors, timely replace aging and failed components, calibrate detection accuracy, eliminate hidden dangers of data errors, ensure the normal operation of sensors, and provide reliable data support for the stable and efficient operation of the cold storage refrigeration system.
