New Vishay Revere JetWeigh-WNew Vishay Revere JetWeigh-W™ Wireless Aircraft Weighing System Has Capacity of 15,000 to 600,000 Pounds, and Operation Range of More than 220 Feet

MALVERN, PENNSYLVANIA — December 15, 2006 — Vishay Intertechnology, Inc. (NYSE: VSH) announces the release of the Vishay Revere JetWeigh-W™ wireless aircraft weighing system. The new JetWeigh-W system, which integrates wireless communication, digital weighing, and high-accuracy load cell technologies, eliminates the need for cable connections. It is an accurate and easy-to-use system that ensures correct weighing even under severe vibration and oscillation conditions.

Applications include routine weight and center-of-gravity monitoring, weight checking after airframe repairs and modifications, and design-proving weight and center-of-gravity determinations.

The JetWeigh-W wireless aircraft weighing system includes a rugged handheld PC that communicates with up to five hermetically sealed load cells, as well as a thermal printer that provides weight result printouts. The system has a capacity range of 15,000 to 600,000 pounds, an operation range of over 220 feet, and accuracy of ± 0.1% of applied load or ± 0.02% of channel capacity, whichever is greater.

The system’s handheld PC features a color touch screen user interface for user-friendly, step-by-step operation. Functions and features include CG calculation, a library of up to 200 aircraft types and characteristics, weighing history, and latitude and altitude adjustment. The system’s hermetically sealed, compact, stainless steel load cells provide a conversion rate of 50 conversions per second per load cell. They enable synchronized sampling of all weight channel results that minimizes vibration, oscillation, and wind effects. The JetWeigh-W system is both highly accurate and, because it is wireless, easy to install, operate, and maintain.
