Abstract
An acceleration sensor having a specific insensitive direction along which no acceleration is detectable and an insulated case supporting the acceleration sensor body. The acceleration sensor body is so mounted on the insulated case that the insensitive direction is along a direction which is neither parallel nor perpendicular to a surface of the insulated case to be mounted on an external device.
Claims14
An acceleration sensor comprising:
- an acceleration sensor body formed of a bimorph piezoelectric ceramic element and having a specific insensitive direction along which no acceleration is detectable;
- and
- a case supporting said sensor body as a center beam and having a mounting surface to be mounted on an external device,
- said sensor body being so supported by said case that said insensitive direction is along a direction being neither parallel nor perpendicular to said mounting surface of said case.
