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 low measurement temperature, choose a large measurement voltage, the accuracy will be doubled, so it is recommended to choose the smallest possible measurement voltage.

The initial value of the measurement area determines the sensitivity of the spectrum, and even determines the type of the detector. The measurement error is significantly smaller than that of the long-wave sensor in the short-wave sensor due to the wrong adjustment of the emissivity. Therefore, in the hot film sensor ( 8 ~ 14μm) at 800°C, the measurement error caused by the wrong adjustment of the emissivity will be five times larger than that of the germanium-photodiode sensor. The permissible measuring range of germanium-photodiode sensors is from about 250°C.
For example, in the combustion process of the ceramic industry or power plants, the measurement range is usually 0 to 1300 °C. In order to avoid large errors, a pyrometer with a short-wave detector should be used.
