Computer batching scales based on industrial control computer as the core, with special ingredients from the meter to receive and display high-precision sensor signal detected by between IPC EIA-RS232 serial port and ingredients meter RS232 serial port data transport, industrial machine can be realized by the weight signal of the sensor during the fast feed ingredients, slow feeding, stop cutting, and transition to the ingredients of another material, it is possible to achieve fully automatic batching of this complex process. It can be widely used food ingredient mixing, Feed, cement, chemicals, building materials, food industry process control.
