Bently Nevada is a name long associated with condition monitoring instrumentation and services, most notably sensors, systems, and diagnostic services for monitoring machinery vibration. The offerings are primarily intended for assessing the mechanical condition of rotating equipment found in machinery-intensive industries such as oil & 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

Eddy current

Eddy currents are electric currents induced in conductors when a conductor is exposed to a changing magnetic field; due to relative motion of the field source and conductor or due to variations of the field with time. This can cause a circulating flow of electrons, or current, within the body of...
