About Us

About Us

Stress-tek was founded in 1978 to provide professional consulting services in the areas of strain gaging, transducer design, and experimetal stress analysis. Since then we have evolved to designing and manufacturing both custom and high volume weighing, force measurement, pressure, and deflection sensors where accuracy and reliability are required. The result is an extensive line of shear beam load cells, bending beam load cells, shear pin load cells, tension and compression load cells, deflection transducers, hydraulic and air pressure sensors. Stress-Tek, also designs and manufactures digital, two-wire electronics to integrate with our load cells and sensors to provide complete solutions.

In 1984 Stress-Tek introduced the double shear beam load cell and the first two-wire digital electronic scale system for on-board applications. These were the first of many products we have designed and manufactured and are now part of our complete product line for the transportation industry know as Vulcan On-Board Scales. We now have over 30,000 systems operating in the trucking industry, and are recognized as a world leader in on-board weighing technology.

But that is just one example. We also provide solutions to such varied markets as timber, trucking, refuse, aggregate, mining, food & beverage, medical, oil & gas, exercise equipment, heavy machinery, and more. Our success results from providing unique, quality products and superior customer service.

In 2015, we became part of Vishay Precision Group, Inc. (VPG), an internationally recognized designer, manufacturer and marketer of sensor and sensor-based measurements systems specializing in the growing markets of stress, force, weight, pressure, and current measurements. VPG is a market leader of foil technology products, providing ongoing technology innovations in precision foil resistors and foil strain gages, which are the foundation of the company’s force sensors products and its weighing and control systems. The product portfolio consists of a variety of well-established brand names recognized for precision and quality in the marketplace, including Stress-Tek! To learn more, visit VPG at
