thermocouple pyrometer
Quick Summary
A thermocouple pyrometer is an instrument used to measure high temperatures, often found in furnaces. It works by utilizing a thermocouple, which consists of two wires made of different metals joined at each end. One junction is placed at the location where the temperature needs to be measured, while the other is kept at a cooler, constant temperature.12
The temperature difference between the junctions creates an electrical voltage, known as an electromotive force, due to the Seebeck effect. This voltage is approximately proportional to the temperature difference. A measuring instrument connected to the circuit converts this voltage into a direct temperature reading. This method allows for temperature measurement without direct contact with the object being measured, which is an advantage of radiation pyrometers.21
