About Vishay Precision Group

Vishay Precision Group produces sensors based on resistive foil technology, and sensor-based systems. They provide vertically integrated products and solutions for multiple growing markets in the areas of stress measurement, industrial weighing, and manufacturing process control. They operated as a part of Vishay Intertechnology until July 6, 2010, when they were spun off as an independent, publicly traded company. Resistors are basic components used in all forms of electronic circuitry to adjust and regulate levels of voltage and current. They vary widely in precision and cost, and are manufactured from numerous materials and in many forms. Foil resistors are the most precise and stable type of resistors available. A strain gage is a special type of resistive sensor for measurement of weights and other types of mechanical stress. In the 1950’s, Dr. Felix Zandman was issued patents for his PhotoStress coatings and instruments, used to reveal and measure the distribution of stresses in structures such as airplanes and cars under live load conditions. His research in this area led him to develop Bulk Metal foil resistors and resistive current sensors with performance far beyond any other resistor available in the global market. In 1962, Dr. Zandman, with the financial help of the late Alfred P. Slaner, founded Vishay Intertechnology to develop and manufacture Bulk Metal foil resistors. Concurrently, J.E. Starr started to produce foil resistance strain gages, which also became part of Vishay Intertechnology. In the last decade, their business has expanded from an initial focus on foil strain gages to include load cells/transducers—a combination of strain gages and the metallic structures to which they are bonded; load cell modules that include electronic instrumentation and software for measuring the load cell output; measurement instrumentation; and complete systems for process control and on-board weighing. Vishay Precision Group's growth strategy largely focuses on vertical product integration, using their foil resistance strain gages in their load cell products and incorporating those load cells and electronic measurement instrumentation (containing foil resistors) and software into their modules and measurement systems. Current sensing foil resistor products are also part of certain control systems that VPG manufactures. Many of their acquisitions in recent years have been directed towards furthering their vertical integration strategy, and they expect to continue to focus their acquisition program in this direction.
