Abstract
A measurement sensor 1 for sensing a physical magnitude and comprising a framework 2, a seismic mass 36 displaceable relative to the framework, and a support frame 8 for the mass 36. The support frame 8 is fixed to the framework and elastically deformable along a sensing axis X.sub.s by the physical magnitude. A transducer 20 is fixed to the support frame 8 for supplying a signal representative of the physical magnitude in response to a deformation of the support frame 8. An arrangement 50, 52, 54, 56 protects the transducer 20 against a force exhibiting at least one component in a plane substantially perpendicular to the sensing axis X.sub.s. The arrangement permits a reversible displacement of the mass 36 relative to the support frame 8 in the perpendicular plane during a shock without acting upon the transducer 20, and a positioning of the mass 36 relative to the support frame 8 in the absence of the shock.
