Abstract
A method of testing temperature sensors of refrigerated cargo spaces, comprising: installing a wireless temperature sensor in proximity of a cargo space temperature sensor of a refrigerated cargo space; receiving, at a data processing device, temperature data from both the cargo space temperature sensor and the wireless temperature sensor; calculating a temperature difference between the temperature measured by the cargo space temperature sensor and the wireless temperature sensor; and calibrating or replacing the cargo space temperature sensor if the temperature difference exceeds a threshold difference.
Claims19
A method of testing temperature sensors of refrigerated cargo spaces, comprising:
- removably installing a wireless temperature sensor in proximity of a cargo space temperature sensor fixed at a return air inlet of a refrigerated cargo space,
- wherein each of the removably installed wireless temperature sensor and the cargo space temperature sensor is configured to measure a temperature of air that is returned from the refrigerated cargo space;
- receiving, at a data processing device, temperature data from both the cargo space temperature sensor and the removably installed wireless temperature sensor;
- calculating a temperature difference between the temperature measured by the fixed cargo space temperature sensor and the removably installed wireless temperature sensor;
- and
- calibrating or replacing the cargo space temperature sensor if the temperature difference exceeds a threshold difference.
A temperature sensor testing system for refrigerated cargo spaces, comprising:
- a wireless temperature sensor configured to be removably installed in a location proximate to a cargo space temperature sensor fixed at a return air inlet of a refrigerated cargo space,
- wherein each of the removably installed wireless temperature sensor and the cargo space temperature sensor is configured to measure a temperature of air that is returned from the refrigerated cargo space;
- and
- a data processing device configured to receive temperature data from both the cargo space temperature sensor and the removably installed wireless temperature sensor;
- wherein the data processing device is configured to calculate a temperature difference between the temperature measured by the fixed cargo space temperature sensor and the removably installed wireless temperature sensor, and
- to indicate the cargo space temperature sensor requires calibrating or replacing if the temperature difference exceeds a threshold difference.
