Bently Nevada 330101-XX-XX-20-02-CN / 147773-00-12 Shaft Proximity Probe – 3300 XL 8mm Series
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft displacement, catastrophic bearing failure, unplanned downtime, and in the worst cases, irreversible damage to turbines, compressors, or pumps worth millions of dollars. The Bently Nevada 330101-XX-XX-20-02-CN proximity probe is the front-line sensor that prevents this scenario — continuously measuring radial shaft position and vibration with micron-level precision, 24 hours a day, 365 days a year.
Within the 3300 XL 8mm Proximity Transducer System, the 330101 series occupies the role of the primary sensing element. Engineered to work seamlessly with the 330130 Proximitor® Signal Conditioner and 330180 cable assemblies, this probe is the global standard for API 670-compliant machinery protection systems across oil & gas, power generation, petrochemical, and heavy industrial sectors. Its eddy-current operating principle delivers non-contact, wear-free measurement that outlasts any mechanical alternative.

Frequently Asked Questions
- Q: What does the “XX-XX” in the part number mean?
- A: The XX-XX suffix positions encode the probe body length and cable length. Common configurations include 05-05 (5-inch body, 5-foot cable) and 08-08. Please specify your required configuration when requesting a quote.
- Q: Is this probe compatible with the older 3300 (non-XL) Proximitor?
- A: The 3300 XL 8mm probe is designed for the 330130 XL Proximitor. While physical installation may be similar, system calibration and scale factor must be verified. Contact us for compatibility confirmation.
- Q: What target material is required?
- A: The standard calibration is for AISI 4140 steel. Other target materials (stainless steel, titanium alloys) require recalibration or a material-specific scale factor correction.
- Q: Can you supply the complete transducer system (probe + cable + Proximitor)?
- A: Yes. Konmask.com stocks complete 3300 XL system assemblies. Specify your gap distance, cable routing length, and rack slot to receive a matched system quote.
- Q: What is the lead time for this part?
- A: In-stock units ship within 3–5 business days. For specific suffix configurations, lead time is typically 7–15 business days. Contact us for real-time availability.
