Abstract: The paper presents the design and experimental characterization of capacitive sensors, plus the relevant front-end acquisition circuitry, for process control in industrial marble machines. The new developed sensing system allows detecting, in real-time and without any contact, the presence of stone samples under the abrasive/cutting heads in an industrial machine. The obtained detection signal is needed as a feedback to improve the automatic control of the polishing/cutting process in marble industry. Different types of sensors are proposed whose performances are assessed through experimental test campaigns considering real industrial working conditions. Compared to state-of-art sensors the proposed solutions allow for a reliable detection while being of low complexity and robust to harsh environment conditions.
Keywords: Capacitive sensors, Industrial measurements, Detectors, Marble industry, Process control, Measurements in dirty/wet environments.
