Bently Nevada 330104-02-08-10-02-00 – Eddy-Current Proximity Transducer System | 3300 Series Platform
Engineering Background: The Bently Nevada 3300 Series Proximity Transducer System is the industry benchmark for non-contact, continuous shaft vibration and position measurement in rotating machinery. Engineered to API 670 standards, this system has been deployed in critical turbomachinery protection applications across power generation, oil & gas, petrochemical, and heavy industrial sectors for decades.
Product Positioning: Part number 330104-02-08-10-02-00 is a complete eddy-current transducer system comprising a probe, extension cable, and proximitor/oscillator-demodulator. It delivers a DC voltage output linearly proportional to the gap between the probe tip and the observed conductive target surface — enabling real-time radial vibration, axial position, differential expansion, and eccentricity measurements with micron-level resolution.

System Architecture & Signal Flow
The 330104-02-08-10-02-00 system operates as a three-component eddy-current chain:
- Probe (330104): Generates a high-frequency electromagnetic field at the tip. As the conductive shaft surface approaches, eddy currents are induced, loading the oscillator circuit.
- Extension Cable: Transmits the RF signal between probe and proximitor with controlled impedance. Length is matched to the proximitor calibration (5 m in this configuration).
- Proximitor / Oscillator-Demodulator: Converts the RF loading change into a calibrated DC voltage output. Output is directly wired to the 3500 Series monitor input card or equivalent DCS/PLC analog input.
Output voltage range: –2 VDC (near gap) to –18 VDC (far gap), with a nominal gap of 50 mil (1.27 mm) at –10 VDC midpoint.

Technical FAQ
Q: Is the 330104-02-08-10-02-00 compatible with the Bently Nevada 3500/42M monitor?
A: Yes. The 3300 Series proximity system outputs a standard –24 VDC-powered, voltage-output signal fully compatible with all 3500 Series transient data and machinery protection monitors.
Q: Can the extension cable length be changed?
A: No. The extension cable length is factory-matched to the proximitor calibration. Changing cable length requires a recalibrated proximitor. Always order the complete matched system.
Q: What is the recommended gap for initial commissioning?
A: Set the initial gap to 50 mil (1.27 mm), which corresponds to the –10 VDC midpoint output. This maximizes the usable linear range in both directions.
Q: Do you supply calibration certificates?
A: Yes. Factory calibration data and certificates of conformance are available upon request for critical applications.
Q: What is the lead time for this part?
A: Typically 3–7 business days for in-stock units. Contact us for urgent requirements.
