Abstract
A dynamometer comprising a testing body which is deformable under the effect of a force which is applied, in the material of which are defined bearing zones capable of receiving four series of windings of prestressed gauge wire remaining in close contact with the testing body, of which two have principal segments oriented parallel to the force applied, while the two others have principal segments oriented perpendicularly to the force applied, these four series of windings forming an electrical bridge arrangement, the segments oriented parallel to the force applied being located in opposite arms of the bridge arrangement, as are the segments oriented perpendicularly to the force applied. The invention is useful for the production of industrial dynamometers.
