Abstract
PURPOSE: To enable an easy and reliable decision by vibration, such as engine knockings, by a method wherein a double resonance state is detected through resonance of a vibration detecting part secured on a vibration plate which comes into a resonance condition or into a condition being nearly the resonance.
CONSTITUTION: A thin cover plate 14, whose periphery part 12 is fixedly caulked at a case body 10 mounted at an engine through the medium of a lock bolt 11, vibrates in a condition to perform a resonanace with vibration of a measured object, such as knocking vibrations, or in a state being nearly said resonance. A cantilever vibration sheet 20, made of a metal sheet, and a vibration detecting part, consisting of a pizo-element 21 positioned at the sheet 20, are mounted at said plate 14, and the detecting part makes a resonance with the vibration of the measured object, such as knocking vibrations. The constitution, which carries said double resonance, froms a vibration sensor which permits can easy and relaible decision of engine knocking vibration, etc.
