Abstract

The module comprises, in an envelope tube, a pendular unit comprising a piezoelectric transducer, PZT, beam, an inertial mass coupled to the free end of the beam, and a beam mount secured to the tube and fastened to a clamping part of the beam. The module further includes a symmetrization insert for calibrating and symmetrizing the pendular unit oscillations in transverse and lateral directions. The symmetrization insert is distinct from the beam mount and comprises a peripheral portion secured to the tube independently of the beam mount, and a central portion with an axial through-cavity inside which the beam extends in said region of free travel. The axial cavity extends between opposite travel limitation surfaces, which are symmetrical and capable of coming into contact with the beam in a bending configuration of the beam.
