Measurement independent of location
The traversable straddle gauge is a highly accurate gauge, measuring the roll form. It is manually set onto the roll, after grinding and traversed along the body length. The system reliably detects the contour of the roll edge to edge with a measurement interval of 1 mm.

Measurement Program
The roll profile is not only measured using this program, but can additionally be interpreted with many program functions (rolling history, compare measurements on the same display, mirror and tilt measurements, …).
While the strip thickness tolerances were a significant criterion for the quality assessment of strip material in the eighties and nineties, significant improvements in controls and automation have made good thickness control a given among suppliers.
During this past fall, we installed our first two – Model A3000 Isotope Thickness Gauges in Mexico. The application was for stainless steel on a heavy-duty reversing mill with 24/7 operation.
In order to accommodate for the high demand in accuracy, quality and yield, it is essential to optimize the existing operating equipment. In the past Vollmer has supplied and been known for their high performance thickness gauges in conjunction with the automation of the screwdown system.
The well-proven BFI version shape measurement roll has undergone a design change that improves its ability to measure the tensions profile on flat product without marking the strip. The detectors have been redesigned to fit into the roll while leaving the surface of the roll completely clear of machined marks. This eliminates the former problems associated with the axially installed sensors.
