Detailed explanation-1: -Pyrometer, which detects the wavelength of thermal radiation, emitted from the hot body, is used to measure the temperature of a very hot body, where physical contact of measurement device cannot be made. Was this answer helpful?
Detailed explanation-2: -High-temperature measurement in the range of 800°C (1, 472°F) and higher presents particular problems and will be the focus of this article. These high-temperature applications are found in the metal processing, power, refining, and other industries.
Detailed explanation-3: -Optical pyrometers operate within the visible spectrum to measure temperatures typically in the range from 700°C to 4, 000°C by comparing the photometric brightness of the heated object against the brightness of a standard source, such as an incandescent tungsten filament.
