Object Calibration Device

    Is the physical check the electrical sub-belt scale into line calibration of the most credible way. 
    Physical detection device works when the material on the belt conveyor belt weighing electronic weighing into the weighing hopper, after weighing the material through the discharge device to return to the delivery system to go. The physical detection device and the belt scale shows the weight of the material to compare, so as to achieve the purpose of checking the belt scale. In order to ensure the accuracy of the physical detection device, the device is equipped with standard weights for approving its own accuracy 
above material weighing method is to go through the belt scale, hopper scales after weighing through. The material can also be pre-weighed by a hopper scale and weighed by a belt scale.
