ABSTRACT:
A vibrating quartz accelerometer of moving object under test, wherein both ends of at least two vibrating quartz resonators are rigidly coupled each other so as to confront their faces each other and to form gap between said resonators, one end of which is made as a fixed end to said moving object and another end thereof is made as a free end to said moving object, a weight is provided on said free end, and when said moving object is put into motion, inertia force, which acts on said weight in the direction for keeping original state of motion or state of standstill relative to said motion, is converted into beat frequency in resonant frequency of said two vibrating quartz resonators, which beat frequency is caught to detect acceleration of said moving object.
