Experimental analysis towards the application of RFID technologies in industrial marble machines

The paper presents an experimental characterization of RFID technologies applied to process control in the marble industry. The final aim is the automatic detection of the presence of a marble slab under the abrasive or cutting heads inside an industrial machine. Four RFID systems at 125 kHz, 13.56 MHz, 868 MHz and 2.45 GHz have been implemented starting from commercially available tags and readers and customizing the set up of the acquisition hardware and of the relevant software. The experimental tests and measures also include dirty and wet working environments representative of those found in real applications.
