What is a pyrometer used for in an engine?

A pyrometer is specifically designed to measure high temperatures, making it an essential tool in monitoring the temperature of exhaust gases in an engine. Exhaust gases can reach very high temperatures, particularly in high-performance or heavily loaded engines, and monitoring these temperatures is crucial for preventing engine damage and ensuring efficient operation.

By accurately measuring the exhaust gas temperature, operators can gain insights into engine performance, fuel efficiency, and the condition of combustion within the engine. If the exhaust gas temperature is too high, it can indicate issues such as lean fuel mixtures or problems with the engine's combustion process, while too low a temperature may suggest incomplete combustion. Thus, using a pyrometer provides valuable data for maintaining optimal engine performance and reliability.
