In a vibrating environment, the requirements of the weighing device are relatively high. In the vibration environment, the stability of the load cell must be higher than the average. The sensor that needs to be selected by the external environment should be selected. Of course, the terminal of the load cell must be well fixed. Prevents problems such as poor contact due to force changes in a vibrating environment. In understanding the fixed terminal, we should first pay attention to the entire load cell fixed.
The invention solves the problem that the weighing device cannot be accurately weighed in a vibration environment, and adopts a comparative compensation method to correct the weighing data under low-frequency random vibration disturbance in real time, thereby greatly improving the weighing accuracy. Field tests have proved that the maximum allowable error of dynamic measurement is ±0.5%, which can meet the trade measurement of bulk materials to a large extent.
