装置有精密钢丝套及钢珠，外由特殊铝合金壳密闭，利用空气充入推动钢珠在钢套中回转钢珠的重量与中心区之间的距离产生离心力产生振动。Means of precision stee sleve and the bal , the outer shell sealed by a special aluminum ally, to promote the use ofair charged into the rotary seve in the stelball weigh ball and the distance between the center of the centrifugal force generated vibration.
振动力度可根据气压调节，价格实惠，使用寿命长、安全，可应用在潮湿、粉尘及防爆场所。
Vibration intensity according to the pressure regulator, affordable, long life, sate, can be used in damp, dust and explosion sites.
