Vishay Nobel GLT Web Tension Load Cells Have Rated Output of 2.000 mV/V +/-0.25%, Are Available in 20-lb, 50-lb, 100-lb, 200-lb, and 500-lb Ratings

Applications Include Winders, Unwinders, Rewinders, Coaters, Laminators, Printing Presses

MALVERN, PENNSYLVANIA — March 21, 2005 — Vishay Intertechnology, Inc. (NYSE: VSH) announces the availability of Vishay Nobel GLT web tension load cells. The high-reliability load cells measure low resultant tension forces with small wrap angles. Designed for use in applications such as winders, unwinders, rewinders, coaters, laminators, and printing presses, they eliminate drift and frequent recalibration problems often encountered with conventional half-bridge semiconductor-type load cells.

Full Wheatstone-bridge, temperature-compensated strain gage construction enables precise accuracy with genuine “non-drift” signal stability. GLT load cells are of a rugged compact size with high overload capacity. Outline dimensions are identical to existing equipment, thereby making possible simple, drop-in replacement.

GLT load cells are ideally suited for a wide range of operating tensions and for applications with high roll weight/low tension ratios and/or wide range requirements. Factory calibration with matching output signals significantly simplifies installation, while ensuring long-term calibration reliability. It eliminates field calibration along with the need for on-site test weights and costly recalibration after initial set-up.

Each load cell can be rotated to measure the resultant tension force, not just a component of the force. The full bridge electrical output of each load cell is calibrated within a tolerance of better than 0.25%. When coupled with Vishay Nobel instrumentation, system calibration can be accomplished without using dead weights or other sources of known force.

Zero and span settings remain stable for tension forces operating at the low end of wide range applications. Scribe marks allow for quick alignment of the GLT load cells with the resultant tension force. Shaft misalignment of up to three degrees is accommodated. Both frame and optional pillow block mounting configurations are available for dead shaft roller assemblies.

The all-stainless steel GLT web tension load cells are available in 20-lb, 50-lb, 100-lb, 200-lb, and 500-lb ratings, and operate over a temperature range of -40 degrees C to +105 degrees C. Rated output is 2.0 mV/V +/-0.25%, while non-linearity and repeatability are 0.25% and 0.02% RO respectively.
