Abstract
An accelerometer for detecting acceleration includes a support, a detection body movable relative to the support upon application of acceleration, a plurality of electromagnets for keeping the detection body floating in the support so that the electromagnets are out of contact with the detection body, a detector for detecting the position of the detection body relative to the support, and a computing section for computing the magnitude and direction of the acceleration exerted upon the detection body according to the detection signal from the detection means. The accelerometer also includes a feedback control section for feeding back the output signal from the computing section to the coils of the electromagnets to control application of current to the coils thereby allowing the detection body to be kept floating at a predetermined position relative to the support.
