Sensors for tracking material in steel and rolling mills, press control and the glass industry. Piros infrared sensors (HMD) recognize the outgoing infrared radiation from hot objects. This infrared radiation ist focused by a lens and directed to a receiver. If the amount of energy of the infrared radiation exceeds the internal set point, then the sensor output is activated >>
