resistance pyrometer

A resistance pyrometer is an instrument used to measure high temperatures. It works by placing a fine wire in contact with the object whose temperature is to be measured. As the temperature changes, the electrical resistance of the wire also changes. The instrument then converts this change in electrical resistance into a temperature reading.1

Resistance pyrometers are a type of pyrometer, which are devices designed for measuring high temperatures, often found in environments like furnaces. Unlike some other types of pyrometers that measure radiation, resistance pyrometers require direct contact with the object. They are related to other temperature-sensitive devices like thermistors, which also utilize changes in electrical resistance due to temperature variations.12
