Bently Nevada 330102-08-15-10-02-00 – 8mm Proximity Transducer System | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for non-contacting eddy-current proximity measurement in rotating machinery protection. Developed by Baker Hughes (Bently Nevada), this platform has been deployed globally in turbines, compressors, pumps, and generators where continuous shaft vibration and position monitoring is mission-critical. The 330102-08-15-10-02-00 is a complete, factory-matched transducer system comprising probe, extension cable, and proximitor/oscillator driver — all calibrated as a unified measurement chain.
Product Positioning
Designed for procurement engineers and reliability teams sourcing OEM-equivalent replacement components for existing 3300 XL installations. This system delivers direct drop-in compatibility with Bently Nevada 3300 series monitors (3300/16, 3300/20, 3500/40M, etc.) without recalibration of the monitoring rack. Konmask.com supplies this unit as a tested, traceable assembly suitable for critical-service applications in oil & gas, power generation, and heavy process industries.

System Architecture & Signal Flow
The 330102-08-15-10-02-00 operates as a three-component eddy-current measurement chain:
- Probe (330102) — 8 mm tip generates a high-frequency electromagnetic field (oscillating at ~1 MHz). As the conductive target (shaft) moves within the linear range, eddy currents induced in the target surface alter the probe’s impedance.
- Extension Cable — low-loss coaxial cable transmits the modulated RF signal from probe to driver. Cable length is a calibrated parameter; the 330102-08-15-10-02-00 configuration specifies a 1.0 m extension for a total system length of 2.5 m.
- Proximitor Driver (3300 XL) — demodulates the RF signal and outputs a DC-proportional voltage (–2 to –18 VDC) representing gap distance. This signal feeds directly into the Bently Nevada monitor rack for display, alarming, and trip logic.
Output polarity: increasing gap → more negative output voltage. Monitors are pre-configured for this convention; no inversion required.

Technical FAQ
Q: Is the 330102-08-15-10-02-00 compatible with the Bently Nevada 3500 series monitors?
A: Yes. The 3300 XL transducer system is electrically compatible with 3500/40M, 3500/42M, and 3500/45 proximity monitor modules. Verify the monitor’s input configuration (standard vs. extended range) before installation.
Q: Can I use a different extension cable length?
A: No. The total system cable length (probe cable + extension cable) is a calibrated parameter. Changing cable length alters the scale factor and requires a new system calibration. Always replace with the identical configuration.
Q: What target materials are supported?
A: The standard calibration is for AISI 4140 steel. Other materials (stainless steel, titanium, aluminum) will produce a different scale factor. Bently Nevada publishes correction factors for common alternative materials.
Q: Is this unit suitable for hazardous area installation?
A: Yes, with appropriate barrier/isolator. The system carries FM, CSA, ATEX, and IECEx approvals. Consult the Bently Nevada installation drawing for the specific entity parameters and associated apparatus requirements.
Q: What is the lead time for this part?
A: Typically 1–5 business days for in-stock units. Contact support@konmask.com for real-time availability.
