Principle of One Color Infrared Pyrometer
At present, one color pyrometers on the market are mostly narrow-band pyrometers.The principle of temperature measurement is to determine the temperature of an object by the amount of radiation energy occurring within a narrow wavelength range.with measuring an average temperature in an area, values is affected by emissivity, lens contamination and background radiation.
The amount of radiant energy emitted by an object is related to its emissivity. The higher the emissivity, the more infrared energy the object emits.The emissivity of an object is related to the state of the object surface. The surface roughness, the degree of brightness and darkness, and different materials all affect the emissivity. Therefore, when using a monochromatic pyrometer, there is often a table of emissivity of different materials.
250 ~ 3000°C InGaAs detector characteristic curve, signal dynamic range 2.1 million times
Changes in emissivity, lens contamination, and the effects of background radiation are
related to the choice of wavelength. Choose special wavelength range can enable the one color pyrometer overcome the interference of transmission medium as much as possible. Such as the influence of water vapor, various gases and other substances.Choose short wavelength can minimize the influence of emissivity.
