How to identify the electronic scale angle difference

In the electronic weighing instrument identification project, one is the identification of the angular difference (1/3zui large weighing), and their mutual difference can not be greater than the identification tolerance (the positive and negative one D of the standard weighing), its performance index is directly Affect the accuracy of electronic weighing.

The electronic truck scale/platform scale requires the identification of the four angular differences of the carrier. The average is divided into four equal parts from the center, and the standard weights of the 1/3zui large weighing are added separately. The error of the indication should be allowed. Check it out. Platform scales and other electronic scales are required to detect the coupling of multiple angles (a few angular differences are detected with several load cells).

The principle and structure of the load cell used in the electronic truck scale/platform: basic double-parallel beams; double-connected parallel beams; five-hole parallel beams; single-row parallel beams. The higher the accuracy of the load cell, the smaller the angular difference of the electronic scale.

Of course, the load cell with higher precision will have a certain angular error, which requires the calibration of the symmetric weight sensor during installation and debugging (the corner), that is, the sensitive part of the corresponding blind hole is closed (there is a certain law ). The closer the display code of the four corners is to the standard code, the higher the accuracy of the scale.
