Bently Nevada 330903-00-05-10-01-05 Eddy Current Proximity Probe – 3300 NSv Series
When a proximity probe fails mid-operation on a critical turbine or compressor train, the consequences are immediate and severe: unplanned shutdowns, costly production losses, and — in worst-case scenarios — catastrophic machinery damage that takes weeks to repair. The Bently Nevada 330903-00-05-10-01-05 is not a commodity sensor; it is the precision front-end of a continuous protection system that stands between your rotating equipment and failure.
Within the 3300 NSv (Non-contacting Vibration) Series, the 330903-00-05-10-01-05 occupies a well-defined technical niche: a 5 mm diameter probe with a 10 mm cable length extension and a 1-metre armored cable, engineered for installations where space is constrained and signal integrity is non-negotiable. Bently Nevada’s 3300 NSv platform is the global de-facto standard for API 670-compliant machinery protection, deployed across refineries, power generation facilities, and LNG plants on every continent.

Key Features & Benefits
- Non-contacting measurement — zero mechanical wear, continuous operation without maintenance intervals
- High-frequency response (DC–10 kHz) — captures sub-synchronous, synchronous, and super-synchronous vibration events
- Armored cable construction — resists oil, steam, and chemical exposure in harsh plant environments
- API 670 compliant — drop-in compatible with existing 3300 NSv monitor racks without recalibration
- Matched probe/extension/driver system — factory-calibrated as a set for guaranteed linearity and sensitivity
- Compact 5 mm tip — ideal for tight bearing housings and limited-access installations
Industry & Equipment Applications
- Steam and gas turbines (radial shaft vibration, axial position)
- Centrifugal and axial compressors in oil & gas and petrochemical plants
- Boiler feed pumps and large centrifugal pumps
- Gearboxes and expanders in LNG and refinery service
- Power generation — combined cycle and cogeneration units
- Marine propulsion and offshore platform rotating equipment
