Abstract
The invention relates to an apparatus for measuring products, including at least one hopper for feeding the product, at least one cell intended to receive the product and provided with a means for opening and closing for arbitrary evacuation of the product after measurement, and a weighing sensor. The apparatus according to the invention is distinguished in that it includes a structure that is movably mounted to reciprocate vertically up and down with respect to a fixed frame, the structure including support means for said cell for driving it in its motion over at least part of its vertical course, and that the weighing sensor is mounted on a part of the fixed frame, and that it is arranged to support said ceil by assuring its measurement, in a predetermined position of the travel thereof, this position called the weighing position, from which a motion of the movable structure in one direction disunites the structure from the cell, while in the other direction, it is the sensor that is disunited from said cell. The invention also relates to a method for measurement by means of such an apparatus.
