Abstract
An accelerometer providing shear isolation from unwanted shear forces by means of a shear isolation member located inside the accelerometer housing. The shear isolation member is rigidly attached to the housing at a mounting end and one or more piezoelectric crystals are mounted on a crystal mounting region. The mounting end is sufficiently far from the crystal mounting region that shear forces exerted on the accelerometer housing are not transmitted through the mounting end to the crystal mounting region, while vibrations, which affect the entire accelerometer, produce shear forces in the crystal which are easily detected.
