Background

The piezoelectric acceleration sensor is widely applied to the fields of industrial monitoring, transportation, test and measurement and the like, and has the characteristics of good reliability, high signal-to-noise ratio, good frequency response and the like. The piezoelectric acceleration sensor utilizes the piezoelectric effect of crystals to complete vibration measurement, a measured body is transmitted to the sensor when vibrating, an inertial Mass block (Mass) generates pressure on Crystal, a Crystal element generates charges, and the charges are converted into corresponding vibration parameters through Charge converter, so that the vibration acceleration is measured. In order to ensure the stable and reliable performance of the acceleration sensor, the installation contact surface needs to be large enough and needs to be in direct contact with a measured body, and the installation mode is reliable enough, at present, the acceleration sensor is generally installed by adopting threaded connection, but the threaded connection has the risk of loosening in the vibration environment, and a proper anti-loosening measure must be adopted.
