Bently Nevada 330101-00-09-10-02-05 – 8mm Proximity Transducer System | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL Proximity Transducer System is the industry benchmark for non-contact, eddy-current-based shaft vibration and position measurement in rotating machinery. Engineered to meet the rigorous demands of continuous process industries, this system delivers sub-micron resolution and exceptional signal stability across extreme operating environments.
Product Positioning
Part number 330101-00-09-10-02-05 is a complete 8mm transducer assembly configured for standard 5-metre extension cable and 5-metre armored integral cable, compatible with the 3300 XL signal conditioning ecosystem. It is the preferred choice for procurement engineers specifying vibration monitoring on turbines, compressors, pumps, and gearboxes where API 670 compliance is mandatory.

Engineering Advantages
- API 670 Compliant: Meets the full requirements of the 5th Edition standard for machinery protection systems.
- Sub-micron Resolution: Eddy-current technology provides repeatable, drift-free gap measurement without mechanical contact.
- Wide Thermal Tolerance: Tip rated to +177 °C enables direct installation in high-temperature bearing housings.
- Armored Cable Construction: Stainless steel armor on the integral cable resists mechanical damage in harsh plant environments.
- Plug-and-Play Compatibility: Direct replacement for existing 3300 XL installations — no recalibration of the driver required when replacing like-for-like.
- Long-term OEM Support: Bently Nevada (Baker Hughes) maintains full calibration data and traceability documentation.
System Architecture & Signal Flow
The 330101-00-09-10-02-05 operates as the sensing element within a three-component eddy-current system:
- Transducer (330101 series) — generates the high-frequency oscillating magnetic field and senses gap changes via eddy-current loading.
- Extension Cable (330130 series) — transmits the RF signal from the transducer to the driver with minimal loss; the 5 m length in this configuration is factory-matched.
- Driver / Oscillator-Demodulator — converts the RF signal to a DC voltage proportional to gap distance; outputs to the 3500 series monitor or DCS analog input.
The complete system is factory-calibrated as a matched set. Substituting individual components from different calibration lots will introduce scale factor errors and is not recommended without recalibration.
Sourcing & Quality Verification
- All units sourced through authorized industrial distribution channels or directly from OEM-certified surplus inventories.
- Each unit undergoes incoming inspection: visual, dimensional, and functional verification against Bently Nevada factory test data sheets.
- Calibration certificates and OEM documentation available upon request for critical-service applications.
- Serialized traceability maintained — serial number cross-referenced against Bently Nevada production records where available.
- Packaging: original OEM packaging preserved where possible; otherwise repackaged in ESD-safe, moisture-barrier materials.
Procurement Process
- Confirm compatibility — verify your existing driver part number and cable lengths match this configuration (5 m + 5 m).
- Request a quote — contact us with your required quantity and delivery timeline.
- Lead time — in-stock units ship within 1–3 business days; ex-stock orders confirmed at time of inquiry.
- Documentation — specify any required certifications (CoC, calibration data, ATEX declaration) at time of order.
- Payment & shipping — T/T, PayPal, and credit card accepted; DHL / FedEx express worldwide.
Technical FAQ
Q: Can this transducer be used with a 3500/42E monitor?
A: Yes. The 330101-00-09-10-02-05 is compatible with the 3500/42E Proximitor I/O module when used with the appropriate driver. Confirm the driver part number matches your monitor’s input card specification.
Q: What target material is the factory calibration based on?
A: Standard calibration is performed on AISI 4140 steel. For non-standard target materials (e.g., titanium, Inconel), a material correction factor must be applied — contact our engineering team for guidance.
Q: Is this unit ATEX certified?
A: ATEX certification applies to the complete system (transducer + driver). The transducer itself carries the necessary markings; confirm the driver’s ATEX rating for your hazardous area classification.
Q: What is the difference between the integral cable and the extension cable?
A: The integral cable is permanently attached to the transducer body and carries the RF signal to the connector. The extension cable connects the transducer connector to the driver. Both lengths are factory-matched in this part number (5 m + 5 m).
Q: Do you provide a warranty?
A: Yes. We offer a 12-month warranty against manufacturing defects. Units that fail incoming inspection are replaced or refunded in full.
