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. For example: in continuous casting, it is necessary to monitor the temperature of molten steel and the temperature of the billet from continuous casting; in the bar rolling workshop, it is necessary to monitor the workpiece at any time, and transmit the signal to the rolling mill or flying shears.

The dual-wavelength pyrometer installs the optical path system (ie, the optical probe) that is basically unaffected by temperature at the temperature measurement site; and installs the signal processing/display with more stringent environmental requirements away from the temperature measurement site, which can ensure the signal processing/ The display always works normally; an infrared optical fiber is used in the middle to transmit the infrared signal received by the optical probe to the signal processor for processing. In this way, the instrument has the stability and reliability of long-term work, and is easy to install, without cooling measures such as water cooling, low cost of use, and convenient equipment maintenance.
