Bently Nevada

Bently Nevada is a condition monitoring instrumentation company, providing services for sensors, systems, and monitoring machinery vibration. The offerings are primarily intended for assessing the mechanical condition of rotating equipment found in machinery-intensive industries such as oil and gas production, hydrocarbon processing, electric power generation, pulp & paper, water and wastewater treatment, mining, and the like.

Bently was a privately held US corporation between 1961 and 2002, during which time it pioneered the eddy-current proximity probe, a sensor that revolutionized the measurement of vibration in high-speed turbomachinery by allowing the direct observation of the rotating shaft. The company also performed significant research in the field of rotordynamics, furthering knowledge of machinery malfunctions such as shaft cracks and fluid-induced instabilities. Its research also helped refine the equations used to describe vibratory behavior in rotordynamic systems.

The company was acquired by GE Energy in February, 2002, and continues to design, manufacture, and market these products and services using the Bently Nevada name.
