ABSTRACT:
The accelerometer comprises: a body intended to be fixed on a component, such as an internal combustion engine cylinder head, whose accelerations or vibrations are to be detected; a piezoelectric element prestressed between the body and a seismic mass; and flexible electrical conductor means between two opposite faces of the piezoelectric element and the terminals of an electrical connector mounted on the accelerometer body, provision being moreover made for an electrical connection between the respective faces of the piezoelectric element and the adjacent parts of the accelerometer. The electrical connector means is mounted on the body of the accelerometer by means of the damping means capable of reducing or suppressing the mechanical transmission of the vibrations or accelerations from the accelerometer body to the connector.
