Common adjustment and repair methods for an eccentric load of weighing sensor of electronic scale
- Technicians can grind each stress concentration surface with a grinding wheel;
- File the stress concentration surface with a file;
- Sand the stress concentration surface with a small sand-blasting gun.
The correction of the eccentric load error of the electronic platform scale In order to correct it better and more conveniently, edit the correction points of the parallel beam sensor and number the correction positions. According to the test and analysis, we divide the correction of eccentric load error into the following 6 cases.
When the loading plate is rotated to A, B, C, D, the outputs are:
The difference between bit A and bit C is small, bit B is small, and bit D is large. At this time, use a file to file 1 point, 1 'point or 2 points, 2' point.
The difference between bit A and bit C is small, bit B is large, and bit D is small. At this time, use a file to file 3 points, 3 'points or 4 points, 4' points.
The difference between bit B and bit D is small, bit C is large, and bit A is small. At this time, use a file to file 4, points or 3 'points diagonally.
The difference between bit B and bit D is small, bit C is small, and bit A is large. At this time, 4 or 3 points shall be filed obliquely.
Bit A is large, bit B is large, bit C is small, and bit D is small., At this time, 4 points are filed diagonally.
