Machinery type: Libra combined with a Metal Detector, designed for weight control and the detection of metals in small-medium products format. This system maximizes profits and minimizes product waste. The system consists of a base that supports the scale and the transport device, a high-sensitivity comparison scale with electromagnetic detector that transforms into an electrical signal the position of the scale plate, burdened by the weight that passes above it, a ribbon transporter and a projector-photocellula group that signals the instant in which the object is about to abandon the scale plate. Employment sector: pharmaceutical, chemical, cosmetic, food, dietary, medical devices. Peculiarity: this' metal detector "line balance, inserted in a transport line of objects of any nature and form, automatically controls the deviations from the nominal weight of the objects, comparing them with predefined limit values. The objects are transported on the line and weighed; their weight is compared with the tolerance limits. thoroughly ensuring accurate weighs. Hz frequency 50 power kW 0.4 total mass kg 100
