Generally, the magnitude of acceleration is difficult to be grasped by human perception. If the transducer is dropped on the floor, it may easily sense acceleration exceeding 9807 m/s 2 (approx. 1000 G) depending on the material of the floor. If a small-capacity acceleration transducer receives an acceleration 10 times larger than the rated capacity, the initial voltage unbalance changes outstandingly, thereby making the transducer unusable due to disconnection of the gage, etc. Thus, the acceleration transducer must be handled carefully
