Digital displayed loop scanners were mainly used in the metallurgical industrial production, to measure the thermal work-piece position where in the view field, and to output the signal, which is proportional to the work-piece angle position. To achieve free tension control for lines and bars.
     Imaging through target object is the principle of this digital displayed loop scanner. This scanner can measure object temperature to 650℃. Main features are:
     *  With high sensitivity gear and low sensitivity gear switch, the minimum temperature  can achieve 650℃.
     *  With new kind high sensitivity CCD, response time is only 2.5ms.
     *  With digital display function, can show the analog value directly.
     *  Especially designed for steel industry, putting the optoelectronic circuits into the heavy protecting shell.
     *  With air purge system and water cooling system.
     *  Provide connector and cables.
