<p>In order to measure forces F exerted on a part in a given direction and in the presence of an external pressure p, the part has integrated therein a sensor (10) which delivers an output signal of the form S = α.F + β.p + η, and said sensor is dimensioned in such a manner as to cause the coefficient β to be zero. To this end, a sensor (10) is used that includes a tube (12) formed by a thinner walled portion (12a) and a thicker walled portion (12b), together with strain gauges (16a, 16b, 18a, 20) mounted in the tube (12) and interconnected to form a Wheatstone bridge.</p> |
