Bently Nevada 330902-36-89-05-01 Eddy-Current Proximity Probe – 3300 NSv Series
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft imbalance, bearing wear, or rotor rub can escalate within minutes into catastrophic equipment failure, unplanned downtime, and six-figure repair costs. In high-stakes environments—power generation turbines, petrochemical compressors, and marine propulsion systems—the proximity probe is not optional. It is the first line of defense. The Bently Nevada 330902-36-89-05-01 is that defense.
Within the 3300 NSv (Non-contacting Vibration) series, the 330902-36-89-05-01 represents Bently Nevada’s precision-engineered 8 mm eddy-current proximity probe, designed for continuous, non-contact measurement of shaft radial vibration, axial position, and differential expansion. The 3300 NSv platform is globally recognized as the industry benchmark for machinery protection systems, deployed across thousands of installations in ISO 10816 and API 670-compliant monitoring architectures. This specific part number encodes a defined cable length, connector type, and sensitivity range, making exact part-number matching essential for system integrity.

Key Features & Benefits
- Non-contact measurement eliminates mechanical wear and enables continuous 24/7 monitoring without process interruption.
- High-frequency response captures shaft dynamic events up to the kHz range, critical for detecting sub-synchronous instability and blade-pass frequencies.
- API 670 compliance ensures direct integration into machinery protection systems without additional engineering validation.
- Robust construction with stainless steel housing and chemically resistant cable jacket, rated for harsh industrial environments including H₂S, steam, and hydrocarbon atmospheres.
- Exact part-number traceability: the suffix string -36-89-05-01 precisely defines cable length, armor type, connector, and calibration—ensuring drop-in replacement without recalibration of the monitoring system.
- Long service life with no moving parts and no consumables, reducing total cost of ownership versus contact-type sensors.
Industry & Equipment Applications
- Power Generation: Steam turbines, gas turbines, hydro generators – radial shaft vibration and axial thrust position monitoring.
- Oil & Gas / Petrochemical: Centrifugal compressors, expanders, pumps – API 670 machinery protection.
- Pulp & Paper / Steel Mills: Large fans, ID/FD fans, rolling mill drives – continuous condition monitoring.
- Marine & Offshore: Propulsion shafting, turbochargers – vibration surveillance in DNV/ABS-classified installations.
- General Industrial: Any rotating machinery requiring ISO 10816 / ISO 13373 compliant vibration measurement.
System Integration & Compatible Parts
The 330902-36-89-05-01 probe is designed to operate as part of a complete Bently Nevada 3300 NSv measurement chain. Typical compatible components include:
- Extension Cables: 330130-xxx-xx-xx (3300 NSv series, matched length)
- Drivers/Oscillator-Demodulators: 3300 XL 8 mm driver (e.g., 330180-X1-05)
- Monitoring Modules: 3500/40M, 3500/42M, 3500/45 (Bently Nevada 3500 rack system)
- Barriers (IS installations): Bently Nevada 3300 series Zener barriers or galvanic isolators
Always verify the complete system BOM against the Bently Nevada System 1 configuration or your site’s machinery protection specification before ordering.

Frequently Asked Questions
- Q: Is the 330902-36-89-05-01 a direct replacement for older 3300 series probes?
- A: The 3300 NSv series is the successor to the original 3300 series. Physical and electrical compatibility depends on the specific driver and extension cable in your existing system. Contact our technical team for a compatibility assessment before ordering.
- Q: Can this probe be used with non-Bently Nevada monitoring systems?
- A: Yes, provided the third-party system accepts a –24 VDC powered eddy-current probe with 200 mV/mil (7.87 V/mm) sensitivity output. Signal conditioning and gap voltage ranges must be verified against your monitor’s input specification.
- Q: What is the typical lead time for this part?
- A: Lead time varies by stock availability. Please submit an inquiry for a real-time availability check. Emergency/AOG orders can often be fulfilled within 24–72 hours from our global partner network.
- Q: Do you provide a warranty?
- A: Yes. All parts supplied by Konmask.com carry a minimum 90-day warranty against manufacturing defects. Extended warranty options are available upon request.
