Material tracking device for tracking material, in particular for tracking rolled plates in the production of sheet metal, under extreme environmental conditions

摘要

A material tracking device (10) is used for tracking materials (3), in particular for tracking rolled sheets in the production of sheet metal, the material tracking device (10) having a transmitter unit (1) and a receiver unit (2), the transmitter unit (1 ) is configured for the unfocused emission of infrared light, the sending unit (1) having a plurality of infrared LEDs (1 ') for sending out infrared light, the receiving unit (2) being configured to register infrared light, wherein the receiving unit (2) is configured to output a first signal or a second signal as a function of the registered infrared light. Furthermore, a method for operating the mobile material tracking device (10), a cooling system (100) and a method for operating the cooling system (100) are proposed.
