Bently Nevada 330103-03-08-10-02-00 – Non-Contact Proximity Transducer System | 3300 XL Series Platform
Engineering Background: The Bently Nevada 3300 XL Series represents the industry benchmark for non-contact, eddy-current-based proximity measurement in rotating machinery protection systems. Developed by Baker Hughes (Bently Nevada), this platform has been deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide for over three decades.
Product Positioning: The 330103-03-08-10-02-00 is a complete proximity transducer system engineered for continuous, real-time measurement of shaft radial vibration, axial position (thrust), and differential expansion on critical rotating equipment. It is fully compatible with Bently Nevada 3500 Series machinery protection racks and integrates seamlessly into existing plant DCS/SIS architectures.

- Wide temperature range: Probe rated to +177 °C, enabling direct installation in high-temperature bearing housings.
- Plug-and-play 3500 compatibility: Direct replacement for existing 3300 XL installations without recalibration of monitor cards.
- Armored cable construction: Stainless steel braid protects against mechanical damage, EMI, and chemical exposure.
- Hazardous area rated: ATEX/IECEx certification supports installation in Zone 1/Zone 2 classified areas.
System Architecture & Signal Flow
The 330103-03-08-10-02-00 system consists of three integrated components operating as a calibrated set:
- Probe (8 mm tip): Generates a high-frequency electromagnetic field; gap changes modulate the field impedance.
- Extension Cable (10 ft): Transmits the modulated RF signal from probe to driver with controlled impedance.
- Proximitor® Driver: Demodulates the RF signal and outputs a DC-coupled analog voltage proportional to gap distance. Output feeds directly into Bently Nevada 3500/3300 monitor input channels.
The calibrated system must be used as a matched set. Substituting individual components from different part numbers will invalidate the scale factor and may cause false alarms or missed trips.

Technical FAQ
Q: Can I use a 330103-03-08-10-02-00 probe with a different Proximitor driver?
A: No. The probe, extension cable, and driver are calibrated as a matched system. Mixing components from different part numbers will produce an incorrect scale factor and is not supported by Bently Nevada.
Q: Is this part compatible with the Bently Nevada 3500 rack?
A: Yes. The 3300 XL 8 mm system is the standard input transducer for 3500/20, 3500/40M, 3500/42M, and 3500/45 monitor modules.
Q: What target material is required?
A: AISI 4140 steel is the standard calibration target. For non-standard shaft alloys (e.g., 17-4 PH stainless, Inconel), a material correction factor must be applied — contact our engineering team for guidance.
Q: Do you provide ATEX documentation?
A: Yes. ATEX/IECEx certificates and EC declarations of conformity are available upon request.
Q: What is the typical lead time?
A: In-stock units ship within 2–3 business days. For sourced units, lead time is typically 5–10 business days depending on origin.
