In situ measurement of effective wavelength by dual-wavelength pyrometer
One of the prerequisites for measuring temperature according to Planck's law is to accurately determine the effective wavelength of the precision photoelectric pyrometer.
Common categories of optical pyrometers
The working current of the high temperature bulb is changed by adjusting the resistance. When the brightness of the filament is consistent with the brightness of the object to be measured,
Criteria for choosing a pyrometer
The application of the pyrometer is mainly determined by the measurement range. Whether it is the measurement voltage or the initial value of the measurement area, it should be consistent with the requirements of the measurement work.
Application of Wavelength Pyrometer in Industry
Thermal imaging systems, namely dual-wavelength pyrometers, have drawn attention to study DED processes because they utilize the ratio of the relative intensities of radiation at two different wavelengths.
Dual-wavelength thermometer tells you the research of long-wavelength infrared thermometer
Infrared radiation: objects above absolute zero (-273.15°C) can radiate infrared energy outward. Infrared detectors are optoelectronic devices that can respond to external infrared light radiation,
Working characteristics of dual wavelength pyrometer
The dual-wavelength pyrometer opens up specific input work through suitable marking activities during use, and mixes the instrument with the temperature required by the factory experiment through the laser modulation frequency.
Advantages of Dual Wavelength Pyrometers
The measurement accuracy error of the dual-wavelength thermometer is very small. For some small temperature changes, it can also be sensitively measured and highlighted.
Industrial application of dual-wavelength pyrometers
Anyone who has an understanding of metallurgical technology knows that in the metallurgical process, temperature signals need to be measured at any time in the process of continuous casting, hot blast furnace, hot rolling, cold rolling, bar/wire rolling, etc.
Choosing the Right Dual Wavelength Pyrometer
Dual wavelength pyrometer technology is playing an important role in product quality control and monitoring, equipment online fault diagnosis, safety protection and energy saving. In the past two decades
