The electronic weighbridge adopts Mitsubishi Electric's MELSEC-A2SHPLC as the main control with Mitsubishi GOT touch screen as the lower human-machine interface (HMI), and the metering control consists of CFW quantitative Filling machine. The weighbridge is connected through CC-Link fieldbus to realize data acquisition and control to ensure the reliability and real-time of dosage. It has rich functions of process operation, monitoring, communication, alarm, management, trending, recording and man-machine dialog, and has strong diagnostic capability.

It has the functions of man-machine interaction, communication, display and storage, printing, etc. Weighing and a variety of functional screens related to operation, such as data and graphic display, status monitoring, data input, information storage, and so on. Each scale is equipped with an advance quantity according to the weighing speed. When the weighing instrument detects that the weight of the electronic weighing material reaches the set value, the advance quantity will be subtracted and the weighing instrument will close the feeding valve. The amount of advance can be corrected manually or automatically, so that the weighing instrument can control the Electronic scale to reach the set target value for each dosage.
