Electronic device for detecting the weight of capsules for pharmaceutical products

A method for detecting the weight of a capsule (1) for a pharmaceutical product, comprising detecting, with a capacitive technique, the weight of a plurality of sectors into which said capsule (1) is divided in a main extension direction thereof;

• wherein detecting comprises:
• arranging a plurality of detection electrodes (S1, S2, . . . , Sn) so that they face a respective sector among the plurality of sectors of the capsule (1), each one of said detection electrodes (S1, S2, . . . , Sn) being designed to form a respective detection capacitor (Ct1, Ct2, . . . , Ctn) with a common plate (5b) defined by a capsule-holding element (2) holding said capsule (1);
• and
• generating a respective output quantity (Vout1, Vout2, . . . , Voutn), which is a function, in an independent and exclusive manner, of the capacitive variation (ΔC1, ΔC2, . . . , ΔCn) of the respective detection capacitor (Ct1, Ct2, . . . , Ctn) and indicative of the weight of the respective sector of said capsule (1), by means of an electronic circuit (12) including a plurality of detection stages (14), each operatively coupled to a respective one of said detection electrodes (S1, S2, . . . , Sn).
