Title: Acceleration sensor
Inventor: SHIBATA JUN
IPC: G01P15/09
Filed: 1990-11-06
Abstract: PURPOSE:To obtain a rugged, highly accurate acceleration sensor by providing a plurality of pressure detecting means for detecting the pressure distribution of fluid with acceleration on the inner wall surface of a cavity wherein liquid is tightly sealed. CONSTITUTION:Piezoelectric elements 1a and 1b which are arranged at the right and left sides so as to face each other are electrically connected to leads 4 through metal thin wires 3. The inside of a case 10 is used as a cavity 11. The elements 1a and 1b are attached to the inner wall surface of the cavity. The inside of the cavity 11 is filled with fluid 12 in a tightly sealed state. By this constitution, when an acceleration sensor is subject to the accelerations in the components in the right and left directions, the pressure distribution corresponding to the accelerations is generated in the fluid 12. The different pressures are applied on the elements 1a and 1b, respectively, and the difference occurs between the generated voltages. The acceleration is computed based on the voltage difference. Namely, e.g. when the pressure in the rightward direction is applied, the fluid 12 is pushed to the left wall surface by the law of inertia, and the pressure on the left wide becomes larger than the right side. The fact is detected with the elements 1a and 1b.
