- 1 - ABSTRACT OF THE DISCLOSURE A DYNAMOMETER HAVING A BENDING BEAM The invention relates to a dynamometer of the type comprising a testing member having a bending beam which has one built-in end and which is elastically deformable in bending under the influence of the force Q applied to its opposite end, as well as sensing means for detecting the deformation of the beam. This dynamometer is characterised by the fact that in the material of the beam, there are defined anchorage zones intended for receiving four rows of windings of prestressed gauge wire having their principal strands directed approximately perpendicularly to the force applied Q and remaining in close contact with the beam in the bending zone,two of the rows of windings having their principal strands arranged along the tensioned fibres of the beam while the other two have their main strands arranged along the compressed fibres of the beam, these four rows of windings forming an electrical bridge assembly. The invention has application in the production of dynamometers and weighing instruments.
