The weighing module realizes signal acquisition, processing, control and output based on digital intelligent module, industrial control computer and RS485 field bus, which constitutes a weighing system with high cost performance. The communication between on-site monitoring computer and management computer is realized by LAN. The software is programmed with VC++ by modular method.

By adjusting the stress consistency of the sensor, the weighing module can reduce the influence of the problem of "static uncertainty" of the multi-fulcrum balance of the weighing platform and ensure the stability of the supporting of the weighing platform, so as to ensure that the bearing capacity of the center of gravity of the weighing platform does not deviate, and to ensure the accuracy of the weighing instrument and the relevant metering performance requirements. The weighing module has been compensated in many ways, including output sensitivity compensation.
