Automatic Gauge Control is a technology used across diverse industrial processes to automatically regulate the thickness or gauge of materials being processed, such as metal sheets or strips.The primary objective of AGC is to consistently uphold a desired target thickness throughout the entire production process.

The VRWSP 900 system, equipped with advanced radar technology, offers a robust solution for precise strip width and strip position measurements. This cutting-edge system combines a transmitter and receiver antenna, harnessing millimeter-wave technology similar to that used in 5G cellular networks. Its versatile frequency range and precise beam focusing enable it to cover extensive measurement ranges with unparalleled accuracy.

This specialized innovation developed in collaboration with VDEh-Betriebsforschungsinstitut (BFI), our BFI Shape Meter Rolls are meticulously crafted to excel in the measurement of diverse metal strip attributes throughout processing. Engineered with precision, these rolls are designed to thrive even in dynamic operational settings, ensuring impeccable measurements.

The contact gauges that measure the thickness of the strip with an accuracy of a few micrometers are renowned for their outstanding precision and exceptional reliability: Almost 2000 systems that have gone into operation worldwide in recent decades are still in use even today. They still form an integral part of the measurement technology in new plants where the highest precision is demanded.

The heart of the system are two gap sensors which measure the gap width on the drive side and operator`s side directly at the shaft of the work rolls, thus eliminating the attenuation of the measuring and adjustment signals caused by stand stretching, roll bearing clearance, etc. The thickness control system thus operates extremely quickly and directly.
