Bently Nevada 330907-05-30-10-02-05 Reverse Mount Eddy Current Proximity Probe – 3300 NSv Proximity Transducer Series
Picture a high-speed centrifugal compressor or steam turbine running blind — no shaft vibration data, no radial position feedback. Within hours, an undetected imbalance, misalignment, or oil-film instability can cascade into catastrophic bearing failure, emergency shutdown, and production losses exceeding tens of thousands of dollars per hour. The Bently Nevada 330907-05-30-10-02-05 Reverse Mount Eddy Current Proximity Probe is the precision sensing element that prevents that scenario. Engineered for installations where standard front-mount access is physically impossible — blocked by machine structure, piping, or confined bearing housings — this probe delivers the full measurement integrity of the 3300 NSv system from the opposite mounting direction, without compromise.
Within the Bently Nevada 3300 NSv Proximity Transducer Series — the industry’s most widely deployed eddy current platform for rotating machinery protection — the 330907-05-30-10-02-05 occupies a precisely defined configuration: reverse-mount geometry, 5 mm tip diameter, 30 cm armored probe cable, 10 mm linear sensing range, 2 m extension cable, and 5 m driver cable. This specific combination is extensively specified across petrochemical, power generation, and heavy industrial facilities worldwide, making it one of the most sourced reverse-mount probe configurations in the Bently Nevada catalog. Its global installed base reflects decades of proven reliability in the most demanding rotating machinery environments.

Key Features & Benefits
- Reverse-Mount Geometry: Installs from the back of the bearing housing — eliminates costly mechanical redesign when front access is obstructed by machine structure or process piping.
- 5 mm Compact Tip Diameter: Fits tight radial clearances common in high-speed turbomachinery without requiring housing modification.
- 10 mm Linear Sensing Range: Wide measurement window for accurate gap calibration and reliable vibration amplitude capture across the full operating envelope.
- Armored Probe Cable: 30 cm armored construction resists mechanical damage in high-vibration, high-temperature cycling environments.
- Drop-In 3300 NSv Compatibility: Direct replacement within existing 3300 NSv installations — no driver recalibration required for like-for-like substitution.
- Non-Contact Eddy Current Technology: Wear-free, continuous shaft position and vibration measurement with zero mechanical contact and no moving parts.
- API 670 System Alignment: The 3300 NSv platform is designed to support API 670 machinery protection compliance requirements.
Industry & Equipment Applications
- Power Generation: Steam turbines, gas turbines, and generator shaft radial vibration and position monitoring.
- Oil & Gas / Petrochemical: Centrifugal compressors, expanders, and process pumps in upstream, midstream, and downstream facilities.
- Pulp & Paper / Steel Mills: High-speed rotating equipment requiring continuous condition monitoring in confined installations.
- Marine Propulsion: Shaft monitoring in confined engine room installations where front-mount access is restricted.
- General Heavy Industry: Any rotating machinery where reverse-mount probe geometry is the only viable installation approach.

Frequently Asked Questions
- Q: What is the difference between a standard mount and a reverse mount proximity probe?
- A standard (front-mount) probe installs with the tip facing the target from the accessible side of the bearing housing. A reverse-mount probe installs from the back of the housing with the tip oriented in the opposite direction — required when front access is blocked by machine structure or piping.
- Q: Is the 330907-05-30-10-02-05 compatible with older 3300 XL or 3300 RAM drivers?
- The 3300 NSv series is designed for NSv-compatible drivers. Compatibility with older 3300 XL or 3300 RAM drivers must be verified against Bently Nevada documentation or confirmed with our technical team before installation.
- Q: Can you supply the complete 3300 NSv system or only individual components?
- Konmask.com supplies both complete system sets and individual components including probes, extension cables, and Proximitor drivers. Contact us with your specific bill of materials.
- Q: What is the typical lead time for the 330907-05-30-10-02-05?
- Lead time depends on current stock availability. Submit an RFQ and we will confirm availability and estimated delivery within 1 business day.
- Q: Can you provide a certificate of conformance or test report?
