About Perfecta Gauge

The Perfecta Gauge is the original PLC-based Thickness Gauge System. From the first installation in the late 90s, Perfecta customers have enjoyed the benefits delivered by the high reliability of the PLC. This system can be built from Allen Bradley, General Electric, Siemens, or Modicon PLCs (others available also). All critical gauge functions run through the PLC.

A PC is usually included to act as the HMI device, but if the PC locks up for any reason, the gauge continues to function. Low cost of ownership is achieved due to the fact that many of the gauge components are off-the-shelf. Perfecta Gauges are installed all over the world in rolling mill applications.
