振動検出器。[Claims for Utility Model Registration] (1) A vibration detector comprising an acceleration detection element, a casing for holding the acceleration detection element, and a mounting member fixed to the casing, wherein the mounting member is attached to a vibrating body to be measured. The vibration detector is mounted parallel to the detection direction of the acceleration detection element on a plane parallel to the vibration direction of a part of the vibration detector, the vibration detector having a detection direction perpendicular to the detection direction of the first acceleration detection element. A vibration detector characterized in that a second acceleration detection element is provided in the vibration detector. (2) √ 2 + 2 is calculated from the detection outputs a and b of the first and second acceleration detection elements, and the amplitude of the vibrating body to be measured is measured from this result. The vibration detector according to claim (1). (3) Calculate √ 2 + 2 from the detection outputs a and b of the first and second acceleration detection elements, and calculate the detection direction or direction of the first acceleration detection element from this result and the detection output a or b. The vibration detector according to claim 1, wherein a vibration angle with respect to a detection direction of the second acceleration detection element is determined. (4) The vibration detector according to claim (3), wherein the attachment member is attached to the vibrating body to be measured so that the detection direction of the first or second acceleration detection element is horizontal.
