Embodiment Construction

[0053] figure 1 A weighing device of the type described in patent application FR 2 734 050 is shown, said weighing device comprising a weighing platform 1 on which the load to be weighed is placed, said weighing platform being supported peripherally by a plurality of sensors 3 . There are four sensors 3 here, and the sensors 3 forming the support of the weighing device are placed on the four corners of the rectangular weighing platform 1 , and each sensor 3 is deformed under the action of the load C placed on the weighing platform 1 . The weighing device also includes an electronic processing unit, which can calculate the force generated by the load C and its application point on the weighing platform plane. The sensors 3 are connected, in particular, to a common electronic circuit 6, which converts the deformation signals sent by the extensometers of each sensor into an intensity I representative of the load C placed, and the position of the point of application of said objec...

Abstract

The apparatus has a comparison unit (10) to compare intensity of a load applied on a plate with a reference intensity and to activate a weight calculating unit (7) or a supplementary electronic unit (8). The unit (8) converts load intensity and / or load position into an alphanumeric character to be displayed on a display screen (4) and which is used for personalizing a memory and / or scrolling a pull-down menu.

Description

technical field [0001] The invention relates to weighing devices of the scale or household scale type, in particular of the electronic type. Said device generally comprises a weighing platform on which the load to be weighed is placed, said weighing platform is supported by at least one sensor which is deformed under the action of the placed load, said device also comprises an elongation unit connected to the measuring electronic circuit. gauge that sends an electrical signal that is a function of the weight to be measured. Background technique [0002] The applicant has described in patent FR 2 623 623 a weighing device of the said type, said weighing device comprising only a single metal bar-shaped sensor, the two ends of which are respectively fixed on the weighing platform of the weighing device and its base. A metal strip forms the test body and supports the extensometer connected to the electronic circuit. When a load is placed on the weighing platform, the metal st...
