Criteria for choosing a pyrometer

(Summary description)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.

Information

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. The larger the measurement voltage is, the smaller the resolution and the poorer the accuracy. , especially when the initial value of the measurement temperature is low, if a larger measurement voltage is selected, the accuracy will be doubled, so it is recommended to choose the smallest possible measurement voltage.

dual wavelength pyrometer manufacturers


The pyrometer model is either a spectral pyrometer or a ratio (two-color) pyrometer. The spectral pyrometer receives the radiant density at one wavelength, unlike the two-color pyrometer with dual sensors and two single sensors, which will measure two different The radiation density of the wavelength, the ratio of the two detector signals reproduces the proportional relationship of the temperature. Due to the intermediary medium such as steam, dust in the radiation of the pyrometer, or the change of the emissivity, to a certain range, the two lines are not connected. Signal changes are displayed. However, the monochromatic spectrum pyrometer will show this change immediately, so the rate pyrometer is preferably used in line-tube converters or in the metal manufacturing and processing industries where radiation interference is more serious.
