Load cell is called the heart the electronic weighing Apparatus. With the science and technology rapid development, made by load cell, the electronic weighing apparatus have widely been applied to all the various occupations, also realized to measure materials fast and the industrial production process increasing and the microprocessor appearance, load cells becomea kind of essential installment in controlling and measuring fromlarge pot/hopper/overhead track scales/automobile scale to vibratory feeding system which mixes all kinds of raw materials. At present, load cells nearly have been applied to all the domain of measuring heavy
