Detailed Description
The present application is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1, the self-sensing three-way instability acceleration sensor includes an aluminum base 1, a main board 2, a nameplate 3, and a connector 4.
As shown in fig. 2 and 3, the aluminum base 1 has a rectangular parallelepiped outline and a cylindrical cavity at the center, a main board 2 is installed in the cylindrical cavity, and a nameplate 3 is installed on the upper surface of the aluminum base 1.
