Bently Nevada 330908-00-20-10-02-05 – High-Precision Eddy Current Proximity Probe | 3300 XL 8mm Transducer System
Engineering Background: The Bently Nevada 3300 XL Proximity Transducer System has been the global standard for rotating machinery protection and condition monitoring for over four decades. Deployed across power generation, oil & gas, petrochemical, and heavy industrial sectors, the 3300 XL platform is trusted by reliability engineers worldwide for its unmatched signal stability, environmental resilience, and direct integration with the Bently Nevada 3500 Series Machinery Protection System.
Product Positioning: The 330908-00-20-10-02-05 is an 8mm eddy current proximity probe configured for standard industrial shaft monitoring applications. Its suffix structure encodes critical configuration parameters — probe length, cable type, connector style, and sensitivity range — making it a precisely specified, drop-in replacement for existing 3300 XL installations. Konmask.com supplies this part through verified industrial channels with full traceability documentation available upon request.

System Architecture & Signal Flow
The 330908-00-20-10-02-05 operates as the sensing element within the complete 3300 XL Proximity Transducer System. Signal flow is as follows:
- Probe (330908-00-20-10-02-05) → generates high-frequency eddy current field at shaft surface
- Extension Cable (330130 Series) → transmits raw oscillator signal from probe to Proximitor® Sensor
- Proximitor® Sensor (330180 Series) → conditions signal, outputs -18 VDC proportional to gap distance
- Monitoring System (Bently Nevada 3500 Series) → processes conditioned signal for alarm, trip, and trending functions
- DCS / SCADA Integration → 4–20 mA or digital output via 3500 rack I/O modules
Note: Probe, extension cable, and Proximitor® Sensor must be purchased and calibrated as a matched system. Mixing unmatched components will degrade measurement accuracy.

Technical FAQ
Q: Is the 330908-00-20-10-02-05 a direct replacement for my existing 3300 XL probe?
A: Yes, provided your existing installation uses the same suffix configuration. Verify probe length, cable type, and connector suffix against your current part number before ordering. Contact us if you need cross-reference assistance.
Q: Can this probe be used with non-Bently Nevada monitoring systems?
A: The probe outputs a standard -18 VDC signal via the Proximitor® Sensor, which can interface with third-party monitoring systems that accept this signal range. However, full system performance is only guaranteed within the Bently Nevada 3300/3500 ecosystem.
Q: Do you supply matched probe/extension cable/Proximitor® sets?
A: Yes. We can source complete matched transducer system sets. Submit your system configuration to support@konmask.com for a bundled quote.
Q: Is a certificate of conformance available?
A: Yes, available upon written request for qualifying orders.
Q: What is your return and warranty policy?
A: We accept returns within 30 days for unused, uninstalled items in original packaging. Defective units are replaced or refunded per our warranty policy.
Q: Can you source other Bently Nevada part numbers not listed on your site?
A: Yes. We specialize in hard-to-find industrial automation components. Submit your parts list to support@konmask.com for a sourcing quote.
