Class A: This is the highest precision grade. Class A load cell has the highest measurement accuracy and stability, and is usually used in applications requiring high precision weighing, such as weighing jewelry, precious metals, etc.

Class B: The accuracy of Class B load cell is slightly lower than Class A, but still has high measurement accuracy. It is suitable for some applications requiring high precision, such as chemical, pharmaceutical and other industries.

Class C: Class C load cell is the most common precision class on the market. It has a high cost performance and is suitable for most industrial and commercial fields, such as logistics, warehousing, food processing, etc. Class C sensors are usually divided into multiple sub-levels, such as C1, C2, C3, etc., where C3 means that the maximum number of degrees of the sensor is 3000, and the accuracy is about three thousandths of the total range.

Class D: Class D is a load cell with a lower accuracy level. Although its accuracy is low, it can still be used in some occasions where the accuracy is not high, such as some simple material weighing.
