Abstract
본 발명은 각진동센서에 관한 것으로서,압전소자(12)의 강성이 상당히 크기 때문에 각진동센서의 감도가 충분히 크지 않고 이에 따라서 증폭회로의 구성에 어려움이 있어 미세한 진동을 측정할 수 없는 것이었다.The present invention relates to an angular vibration sensor, and because the rigidity of the piezoelectric element 12 is considerably large, the sensitivity of the angular vibration sensor is not large enough, and thus, the structure of the amplification circuit is difficult and thus minute vibration cannot be measured.
이를 해결하기 위하여 본 발명은,베이스상에 탄성변형체의 중앙이 지지되고 상기 탄성변형체에는 중앙으로부터 동일한 거리에 압전소자와 지진 질량체를 형성함으로써 각진동센서의 감도를 증가시킬 수 있고 병진운동에 영향을 받지 않으며 베이스의 변형에 의한 신호간섭을 최소화할 수 있도록 한 것이다.In order to solve this problem, the present invention, the center of the elastic deformation is supported on the base and the piezoelectric element and the earthquake mass at the same distance from the center in the elastic deformation can increase the sensitivity of the angular vibration sensor and affect the translational motion The signal interference caused by deformation of the base is minimized.
