Research on the whole cycle tilt weighing technology of cantilever beam electronic scale

In the process of using cantilever type electronic scale, the level of installation position is the premise to ensure its accuracy, but in practical application, the installation plane is often non horizontal, such as the electronic scale on the vehicle, the electronic scale on the transport belt and so on. In this way, the accuracy of the electronic scale will be reduced, resulting in inaccurate weighing and even large error. According to the working mechanism of the cantilever type weighing sensor, an algorithm is proposed to compensate the weighing error when the cantilever type electronic scale is tilted all around. The automatic compensation of the weighing error is realized when the tilt angle between the platform and the horizontal plane is less than 12 degrees. The results show that the no-load indication error is 0 and the absolute value of full load indication error is less than 5g for the double hole cantilever beam electronic scale with the range of 30000g and resolution of 5g.
