MALVERN, PA--(Marketwire - March 2, 2011) - Vishay Precision Group, Inc. (NYSE: [ VPG ]) today announced that its VPG Process Weighing division has introduced a new-generation roll force measurement system for use in hot and cold rolling mill applications with its BLH-Nobel Weighing Systems G4 family of multi-channel weight/force indicators.

Designed for new and existing rolling mills, the RFS-4 system provides the mill operator with continuous monitoring and display of the roll separating force and differential forces indicating balance. In addition, the system automatically cancels temperature-induced drift during the period that the mill is empty and provides local and remote indications if metal is accidentally introduced into the mill or the mill becomes overloaded.

Easy to set up and use, the new RFS-4 measures rolling mill separation forces accurately and conveniently, and with a high degree of repeatability, using extensometers on the mill posts or load cells in the screw to provide an electrical signal proportional to the mill separation force. A single G4 instrument with customized software reads signals from both sides of the mill and amplifies them.

In the rare event of an extensometer failure during rolling operation, system software highlights the failing channel and electronically compensates for the loss until the unit is replaced, eliminating lost production time.

Compared with the previous-generation system, the new RFS-4 requires only one external G4 signal conditioning unit. The G4 has up to eight channels to provide accurate and reliable information on sum (total), difference (work-drive), work total, and drive total values that can be displayed on the graphic color display. Analog signal outputs for each value are available on the read panel rack terminals, with separate relay outputs provided for "Metal in the Mill" and "Mill Overload" conditions.
