Patent ID: 6951988

Claim:
A device for weighing an object by lifting, comprising: a base ( 2 ); a slide ( 3 ) mounted so that it can move vertically on said base ( 2 ); drive means ( 5 ) for moving said slide ( 3 ) with respect to said base ( 2 ); an electronic sensor ( 6 ), secured to said slide ( 3 ) in terms of vertical movement and arranged on said slide ( 3 ) in such a way as to be inserted between the latter and said object when said drive means ( 5 ) operate said slide in order to lift said object, said sensor ( 6 ) delivering a first measurement signal representative of the compressive load to which it is subjected; and means ( 22 ) for reading said first measurement signal, characterized: in that said electronic sensor ( 6 ) is able, in a way known per se, in addition to deliver a second measurement signal representative of the shear load, transverse to said object, to which it is subjected; and in that said device comprises comparison means ( 25 ) for comparing said second measurement signal with a threshold value so as to validate, or invalidate, said first measurement signal.
