Profex In-Line – laser measurement of rolled product profiles

The measurement of profiles of rolled products online is a contactless device that allows laser measurement of profiles of rolled cold and hot products directly in operation.

Effective protection with heat shields, air conditioning, and deflectors of widescreen sensor sights allows the device to be placed in the immediate vicinity of the rolling mill. Unique design in the shape of a “C” allows the device to leave and get to a safe place in case the rolled product gets jammed on the line. In the event of an emergency, it is designed to withstand radiant heat and the sensors are not damaged.

The system is based on the laser triangulation method and is capable of capturing the entire perimeter (cut) of the product at one point. Appropriate layout enables 3D evaluation of scanned data and display of all measured parameters that the operator needs for efficient production control.

Of course, it also includes the feature of archiving all the measured data for later evaluation and processing. Fiber optic and Ethernet interfaces ensure reliable data transfer with the superior system even over long distances without interference with the surrounding technology.
