The principle of temperature measurement by infrared
Any object transmits the infrared radiation, and the radiation intensity
varies with temperature. Infrared temperature measurement uses thermal radiation within the range of wavelength 8-14um.
The infrared thermometer is a kind of hot-electron sensor which can
receive the infrared radiation and transform it to a measurable electric signal, and itsmain assemblies are as following:
• Lens
• Spectrum filter
• Detector
• Electronic circuit (Amplifier/ linearization/ signal processing)
Light path of the infrared thermometer is determined by the specification
of lens. The spectrum filter can choose the best spectral range for temperature measurement.The power of infrared radiation can be transformed to electric signal by detector and electronic circuit.

Cautions: . This instrument is not recommended for the measurement of bright or polished metal surfaces (non-ferrous metal objects such as stainless steel, aluminum, etc.); The reflections will affect the accuracy of the measurement. . The temperature can not be measured through the glass , otherwise the temperature value will only be the surface temperature of the glass. . The accuracy of the measurement will be affected by the steam , dust, smoke, etc. | ||
