Deformation transducer exhibiting a test body (30) of conductive material on which there is deposited at least one strain gauge (31, 31, 33, 34) by means of an insulating material. This transducer is connected to a measuring circuit (40, 43). It is characterised in that between the gauge and the test body there is interposed a conductive screen (45) brought to a specified potential and insulated in relation to the test body and to the gauge. This screen eliminates the parasitic voltages resulting from potential differences Vp between the reference of the measurement circuit and the test body (30). <IMAGE>
