What is the working principle of thermocouple? The principle of the thermocouple. The voltage is measured to derive the temperature. In practice, leads A and B are connected to a digital voltmeter (DVM), digital multimeter (DMM), digital data acquisition system, or other voltage measuring device.
What is the purpose of thermocouple?
A thermocouple is basically a device that measures temperature. Unlike a thermometer, which relies on the thermal properties of a material such as mercury, a thermocouple measures temperature by generating an electrical voltage.
How accurate is thermocouple?
Thermocouples are used in an extremely wide temperature range (see Table 1). The electromotive force of a metal conductor thermocouple is typically 5 to 60 millivolts. The accuracy of the temperature display is usually within a few degrees K. Some thermocouples are accurate to ~° K.
