The operation of a type J thermocouple is based on the generation of an electrical signal when its two different metals (iron and constantan) come into contact with different temperatures. This difference in electrical potential translates into an accurate temperature reading.
To ensure proper performance, it is essential to choose a suitable type J thermocouple cable, as the quality of the wiring directly influences the accuracy of the measurement. In addition, the correct connection of the type J thermocouple ensures that the sensor delivers stable and reliable data.
For more detailed information on its performance, refer to the type J thermocouple table, where you can find the voltage values generated as a function of temperature.
