Enjoy the PLC design reliability

The Perfecta Gauge is a high performance X-ray thickness gauge that features the industry's first open architecture. Designed on a PLC platform, its combination of advanced technologies make Perfecta gauges accurate, versatile and robust; they consistently outperform most other gauges on the market. Wherever possible, it has been built with broadly available hardware and software components, including off-the-shelf PLC, PC, networking protocols and software. This reduces both initial costs as well as drastically cutting maintenance costs. The Perfecta Gauge is intended for use as a control gauge for Rolling Mill and Process Line applications and is suitable for measuring the thickness of a variety of metallic and non-metallic materials. The Perfecta Gauge is available in Centerline, Scanning, and Profile configurations.

High reliability / performances ratio with Perfecta

Response time
The response time is a measure of the time lag between the actual change in a measured thickness and the corresponding change in the gauge's voltage output (AGC output). Typically this is measured at a baseline thickness of 0. 100" of steel. For the Perfecta, the response is adjustable to less than 10 milliseconds, offering excellent production control.

The accuracy of the gauge is within +/- 0.10% of the set thickness of the precision master on which the gauge has been standardized.
