PROgauge® for sections and rails

Contactless precision measurement

Also available to you are PROgauge® measurement systems. They provide online product parameters so you can perfectly monitor and control your rolling or production process. The core technology behind all applications is the same: contactless measurement of cross-sections by two-dimensional triangulation. What's different each time is that we customize your measurement system to your product portfolio and infrastructure, for example your rolling mill layout.
