An American company built on strain gage technology…
Dr. Arthur C. Ruge of Massachusetts Institute of Technology (MIT) and E. E. Simmons of California Institute of Technology (Caltech) are credited with the simultaneous but independent development of the strain gage in 1937-38. Eventually Ruge teamed up with Professor Alfred V. deForest, inventor of a mechanical strain gage, and of the two partners established Ruge-deForest Inc. This arrangement continued until 1955 when Baldwin-Lima-Hamilton (BLH) bought the company and founded BLH Electronics.
…teamed up with Swedish load cells experts
The Nobel part of the BLH Nobel history originates from the Swedish arms technology company Bofors, shaped under the ownership of world-renowned inventor Alfred Nobel.
In the late 1950s Bofors started a new business branch within weighing that initially focused on laboratory weighing then expanded to include industrial weighing. The company manufactured and developed high accuracy load cells. One product in particular played an important role in the company’s success; the patented KIS load cell, known for its resistance to twisting forces and side forces.
In 1976 Bofors acquired BLH Electronic and in the mid-80s, the Bofors load cell division formed a new company that became Nobel Elektronik, then Thermo Electron.
All weighing and force measurement expertise collected under one global brand: Vishay
In 2002 all the Nobel and BLH expertise was collected under the same global brand: Vishay Intertechnology, by then the world’s leading manufacturer of foil resistors and strain gages. This was a part of Vishay’s strategic acquisitions of load cell companies like Tedea-Huntleigh and Celtron among others, making Vishay one of the world’s largest manufacturers of load cells for weighing and force measurement.
Vishay Precision Group (VPG) spins off from the mother company
As Vishay Intertechnology grew through innovations and acquisitions, its resistive foil technology products became non-core businesses. In 2010, Vishay Intertechnology spun off these non-core businesses into an independent company listed on the New York Stock Exchange: Vishay Precision Group (NYSE: VPG).
VPG is an internationally recognized designer, manufacturer and marketer of systems and components based on its resistive foil technology, sensors, and sensor-based systems; specializing in the growing markets of stress, force, weight, pressure, and current measurements.
BLH Nobel is one of the brands in the VPG weighing and control systems portfolio, alongside KELK and VPG Onboard Weighing.
