Technical Description
The C5220 uses a 24-AWG, twisted pair, shielded, fast response type E thermocouple. Type E thermocouples consist of a chromel wire and a constantan wire joined at a measurement junction. A voltage potential is generated when the measurement end of the thermocouple is at a different temperature than the reference end of the thermocouple. The magnitude of the voltage potential is related to the temperature difference. Therefore, temperature can be determined by measuring the differences in potential created at the junction of the two wires.
A reference temperature measurement is required for thermocouple measurements. The temperature sensor built into many of our dataloggers' wiring panel typically provides
this measurement.
The C5220 consists of a stainless-steel overbraided cable and a thermocouple extension cable. Adhesive on one end of the overbraided cable secures the sensorto the solar panel. The mini connectors of the thermocouple extension and overbraided cables attach to each other. The pigtails of the extension cable connect to the datalogger.
The C5220 can provide the temperature on the back of a solar panel, which is an important measurement in solar energy applications. The output of a solar panel is affected by its temperature. As the temperature of the solar panel increases, its output decreases.
