Rolling machines are large and complex, requiring measurements at many points to completely characterize their operation. Variations in rolling processes variables such as temperature, speed, pressure, and tension can result in output that varies in consistency and thickness. A data acquisition and control system from VXI Technology is well-suited to characterize a rolling mill process. Thousands of transducer readings can be performed each second and extensive triggering capability ensures correct time sequencing. Extensive control output capability allows a process characterization system to grow into a complete control system as needed.
