Weight sensing module issue
Thread Content
We have a weighing module here; when the weight is below 8 tons, the error is within 0.3 percent. However, when the weight exceeds 8 tons, the error increases as the weight rises, reaching up to 20 percent in some cases. How can this problem be solved?
Are the errors different across different weight ranges?
It’s your fault for going beyond the weighing range! ! ! This is the conversion of coefficients in the program.
Before 8t, there is basically no error; after 8t, the error gradually increases, reaching its maximum at the full scale of 12t
1. Was this container calibrated using theoretical methods? Theoretical calibration can involve a certain degree of error, and problems of this kind occur when proper calibration is not carried out； 2. If calibration is not performed using theoretical methods, an equal amount of water or weights is used; the amount of water used for calibration is limited, and accuracy is only good near the calibration point. At larger ranges, the linearity deteriorates (some instruments have a low threshold for calibration, allowing calibration even at levels below 20%) ； 3. If neither of the above issues exists, check whether there are any foreign objects stuck in the weighing sensor, which may result in very minimal deformation of the sensor ； 4. Problems with the sensor itself; factors such as overload damage may cause the sensor to lose its linearity ； Engineer Li from Zhongchuang ZhiKong: 13924180225, HBM load cells
