To analyze the working principle of the weighing module, we can take a typical chemical reactor electronic platform as an example. Three or four pressure weighing modules installed at the bottom of the reactor transfer the weight signal of the kettle to the junction box. The signal of each weighing module is connected in parallel in the junction box, and the angular difference can be adjusted according to the load condition of each weighing module, and the collected weight signal is sent to the weighing end or the weight transmitter. The weighing terminal or weight transmitter processes the weight signal into corresponding weight data.
