Inaccurate Temperature Reading for Reefer Truck
My refrigerated trucks are installed with temperature sensors and for one of my trucks, the displayed temperature is inaccurate or above the normal level.
The platform might have displayed inaccurate temperature for your refrigerated truck at times for many reasons. The type or make of the GPS tracker, how the GPS device and the temperature sensors are installed in the refrigerated truck, how the temperature sensors are placed inside etc. One should always be very thoughtful while installing or mounting a temperature sensor. A proper installation would always report accurate temperature reading.
Things to keep in mind while installing a temperature sensor in your refrigerated truck Please make sure that there is no external heat or cooling source close to your sensor.
Things to keep in mind while installing a temperature sensor in your refrigerated truck
- Please make sure that there is no external heat or cooling source close to your sensor.
- No other objects should be a hindrance for the sensor to generate the exact reading.
- Do not cover the sensor with any other objects.
Analysing the temperature value displayed in the platform may help you determine the possible reason for incorrect reading.
