Explosion-proof weighbridge consists of three basic units: weighing platform, load cell, and weighing instrument; the load cell part includes weighing instrument, weighing platform and signal cable. It adopts RS485 interface to communicate with digital load cell, and it can be adjusted manually/automatically for bias load (four-corner adjustment), address and read data of single sensor automatically, and modify the sensor number on the spot automatically. It can realize the processing of data, such as: display, calibration, sending, storage, printing and other functions.

It can realize the processing of data, such as: display, calibration, sending, storage, printing and other functions.
Explosion-proof weighbridge is mainly composed of load cell, weighing instrument, programmable controller (PLC), frequency converter, industrial control machine and printer. During the dynamic weighing process, it accepts the weight signal from the weighbridge. When the weight of material in the hopper reaches the set value, it outputs I/O quantitative signal to PLC, which collects the quantitative output signal from the weighing instrument, and controls the output frequency of each frequency converter through PLC, thus controlling the amount of coarse and fine material of the corresponding vibrating Feeder and the opening and closing of the material door of each hopper. The industrial computer communicates with the weighing instrument through RS232 interface, and displays the weighing data of each weighing scale on the monitoring screen, and the user can adjust the formula on the panel of the weighing instrument or on the operation interface of the industrial computer. During each batching work, the powerful logic control function of PLC is utilized to make the vibrating feeder take both sequential and synchronous work according to certain logic, and the weighing hopper also works at the same time, which saves time and cost.
