OPTICAL PYROMETER Meaning and
Definition
-
An optical pyrometer is a sophisticated temperature-measuring device that utilizes the principles of optics and radiometry to determine high temperatures accurately. It operates by measuring the radiation emitted by a heated object and then using this information to infer the object's temperature.
The process involves the device's optical system collecting and focusing the radiant energy emitted by the object onto a sensor, typically a photodetector or a thermopile. The sensor then converts this optical signal into an electrical signal, which is subsequently analyzed to determine the temperature of the object.
Optical pyrometers are commonly used in industrial and scientific applications where non-contact temperature measurements are necessary due to extreme temperatures, moving objects, or confined spaces. They offer advantages such as high accuracy, fast response, and the ability to measure temperatures beyond the range of contact-based thermometers.
To calibrate an optical pyrometer, a reference temperature scale is used, such as the International Temperature Scale of 1990 (ITS-90) or the Planck radiation law. By comparing the radiation emitted by the object with the known radiation emitted at specific reference temperatures, the optical pyrometer can calculate and display the temperature of the object.
Overall, an optical pyrometer provides a reliable and efficient means of measuring high temperatures in various industrial settings, including metal processing, glass manufacturing, and scientific research.

Etymology of OPTICAL PYROMETER
The word "optical pyrometer" is made up of two components: "optical" and "pyrometer".
1. Optical: The term "optical" comes from the Latin word "opticus", which means "visual" or "pertaining to sight". It is derived from the Greek word "optikos", which means "of or for sight". The word evolved over time, and in the early 17th century, it began to be used to refer to anything related to vision or sight.
2. Pyrometer: The term "pyrometer" is composed of two Greek words: "pyro" meaning "fire" and "meter" meaning "measure". In the mid-19th century, there was a growing need to accurately measure high temperatures in industrial settings, particularly in applications involving heat and combustion.
