What is the millivolts power output on a thermocouple closed circuit test?

The millivolts power output on a thermocouple closed circuit test typically falls within the range of 10 to 15 millivolts. This value is crucial because it indicates how effectively the thermocouple is generating a voltage in response to a temperature difference between its junctions. In a properly functioning thermocouple system, each type produces a specific voltage range depending on the materials used and the temperature gradients applied.

The selected range (10 to 15 millivolts) reflects typical output for many common thermocouples when exposed to an appropriate temperature difference, allowing them to be effectively used in temperature measurement applications within the specified operational parameters. Understanding this output helps in assessing the performance of thermocouples in real-world applications.
