Two-colour fixed pyrometer operating principle instruction
Dual-colour fixed pyrometer operating principle guide: dual-colour infrared thermometer is a kind of infrared thermometer. Can also be called fibre optic dual-colour infrared thermometer that measures the brightness of the infrared radiation emitted by the object in two different spectral ranges and by the ratio of the brightness of these two radiations to infer the temperature of the object, known as dual-colour pyrometer. In fact, dual-color pyrometer does not have the meaning of brightness and colour, and brightness pyrometer (optical pyrometer) compared to the two are different in principle. The meaning of "colour" here is infrared wavelength or spectrum, i.e. "dual infrared spectrum pyrometer".
Dual-colour on-line pyrometers are an effective tool for detecting and diagnosing faults in electronic equipment. Fixed infrared thermometer has a variety of varieties, different series in their respective industries play a more important role. The main performance indicators of fixed infrared thermometers are spectral response, response time, repeatability and emissivity. Fixed infrared thermometer for the glass and ceramics industry, paper and packaging industry, various types of kiln temperature measurement applications and the chemical industry to measure the temperature of instruments and other instruments, so as to detect the operation of the instrumentation to ensure the normal operation of an instrument.
Two-colour fixed pyrometer operating principle guide:
Two-colour infrared thermometer by the optical system, dichroic or filter, infrared detector, signal processor and display output part of the composition. Two-color pyrometer is to measure the object in two different spectral ranges issued by the amplitude of brightness, and the two irradiance ratio converted to the temperature of the object, therefore, in principle, fundamentally different from the single-colour pyrometer, two-colour pyrometer is the key in the selection of the two bands. The principle of choice: the ratio of the signal of the two bands is sensitive to changes in temperature, when the temperature has a small change, the ratio of the signal in the two bands is still very large, so that the instrument will have a greater temperature resolution.
