ACCELERATION SENSOR |
摘要 |
An acceleration sensor (1) includes a parallelepiped case (2). A circuit board (3) is secured in the case (2). A sensor chip (5), on which a diffusion strain gauge (5b) is formed, is mounted on the circuit board (3). A cylindrical acceleration selecting element (13) is provided on the case (2). The axis of the acceleration selecting element (13) extends in the x direction. A cylindrical pressure transmitting element (14) is also provided on the case (2). The pressure transmitting element (14) communicates a hollowed part on the top of the sensor chip (5) with the interior of the acceleration selecting element (13). The hollowed part on the top of the sensor chip (5), the pressure transmitting element (14) and the acceleration selecting element (13) are filled with silicon gel (10). <IMAGE> |
