Abstract

The invention discloses a method for installing an inertial sensor unit and the inertial sensor unit. The method for installing an inertial sensor unit includes: attaching a substrate to a structure with a magnet; and attaching a case accommodating an inertial sensor, to the substrate. The case is provided with a first attachment part. The substrate is provided with a second attachment part. In the step of attaching the case, the first attachment part and the second attachment part are fitted together to attach the case to the substrate. The inertial sensor has a base part, a moving part coupled to the base part, a physical quantity detection element arranged at the moving part, and a mass part arranged at the moving part. The mass part is made of a non-magnetic material.

Description

technical field [0001] The present invention relates to a mounting method of an inertial sensor unit and an inertial sensor unit. Background technique [0002] Conventionally, inertial sensors such as acceleration sensors that detect acceleration and gyro sensors that detect angular velocity are known. [0003] For example, Patent Document 1 describes an acceleration sensor including a double-tuning-fork vibrating element made of crystal. In addition, Patent Document 1 describes that a mass portion made of metal is provided on a movable portion of an acceleration sensor. [0004] An inertial sensor unit including the inertial sensor described above is attached to a structure in order to detect vibration of a structure such as a building. When the inertial sensor unit is mounted with a magnet, there is a possibility that an impact due to the momentary attraction of the magnet will be applied to the inertial sensor.
