<p>The subject of the invention relates to a measurement sensor comprising: . at least one electrically conducting measurement element (10), . a system (30 or 50) for exciting (energising) the measurement element, along the vibration plane, comprising a current source (31) supplying the measurement element and at least one pair of magnetic (32, 33) or capacitive (51, 52) excitation pieces comprising planar active faces (32a, 33a or 51a, 52a), . and a system (30 or 50) for detecting the effect of the Coriolis force. According to the invention, the detection system (30 or 50) comprises, in combination with the magnetic (32, 33) or capacitive (51, 52) excitation pieces, at least one pair of capacitive (51, 52) or magnetic (32, 33) detection pieces respectively, mounted in parallel with the excitation pieces, in order to detect the variation of the magnetic or electric field under the effect of the Coriolis force applied to the measurement element with a view to allowing measurement of an angular speed. <IMAGE></p> |
