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.

A dynamic weighing device and weighing method authorized by the Intellectual Property Office
[China Instrument Network Instrument R&D] Recently, an invention patent of Zhejiang Measuring Institute “a comparative dynamic weighing device and low-frequency dynamic weighing method†was authorized by the State Intellectual Property Office. The invention patent can be widely applied to dynamic weighing devices in the industrial field, and in particular, it is used on weighing devices on ship unloaders, and is the first case in the world. A comparative dynamic weighing device and low-frequency dynamic weighing method is a brand-new weighing device. The dynamic weighing device includes a weighing device for compensation, a first weighing sensor, a weighing bin, and a dual-channel weighing meter. The compensating weighing device and the first load cell are fixed on the supporting plate, and the measuring silo is installed on the first weighing sensor. The compensating weighing device includes a second weighing sensor fixed on the supporting plate. The weighing platform fixed on the second load cell and the weight fixed on the weighing pan; it also provides a comparative method of low-frequency dynamic weighing method, using a dynamic weighing device, through the sensor to collect the calculation parameters, effective The method solves the problem of parameter measurement, adopts a comparative method, and carries out dynamic measurement through a compensation and correction formula to effectively solve the measurement problem based on low-frequency random vibration.
