Product Description
Product Overview
The Bently Nevada 84661-35 is a Velocity Seismoprobe designed for industrial automation and machinery condition monitoring. Manufactured by Bently Nevada (a Baker Hughes brand), this sensor measures casing vibration velocity in rotating machinery, providing critical data for health monitoring without requiring proximity to the shaft. It is part of the Bently Nevada velocity sensor lineup, suited for applications in harsh environments like oil and gas, power generation, and manufacturing, typically used on equipment such as pumps, fans, and compressors. The "-35" suffix likely indicates a specific configuration (e.g., cable length or mounting), but without exact documentation, I’ll base this on the closely related 84661 series.
