Description
The Bently Nevada 330180-X1-00 (incorporating modification code 145004-13) is a 3300 XL series 5-mm/8-mm Proximitor sensor. This specialized conditioning unit converts the high-frequency eddy-current RF gap signal generated by a proximity probe into a continuous, linear DC voltage proportional to the dynamic shaft vibration or static position of a fluid-film bearing machine. The 145004-13 variant features factory-altered internal circuitry tuned for alternative target shaft metal substrates, diverging from the standard AISI 4140 steel calibration curve.

Technical Features & Field Engineering Context
Target Material Recalibration Dynamics
Standard off-the-shelf Bently Nevada Proximitor sensors are factory-adjusted for AISI 4140 steel. Because eddy-current penetration depth and magnetic permeability vary significantly across different alloys, deploying a standard sensor on alternative materials leads to severe scale-factor errors. The MOD 145004-13 features custom component tuning at the factory to correct this curve shift. When commissioning this module at 2 AM, ensure that the mechanical shaft metallurgy precisely matches the 145004-13 factory material tracking documentation before finalizing alert and danger setpoints.
Electromagnetic Compatibility & RFI Mitigation
The 3300 XL platform introduces extensive internal shielding enhancements over obsolete 7200 and early 3300 series iterations. This structural engineering choice provides advanced immunity to radio frequency interference (RFI). It allows the module to meet strict CE marking guidelines without requiring specialized metallic conduit wraps or enclosed metal junction matrices, lowering broad-scale loops costs.
Commercial and Logistics Status

- Warranty Period: 12-month comprehensive warranty covering operations from the date of transport.
- Global Lead Time: Standard allocation items ship within 2 to 4 business days.
- Documentation: Factory tracking sheets and modification records should be verified before swapping units within high-speed turbomachinery trip loops.
Commercial Note: Because this unit features a specific material modification sub-code, market availability fluctuates based on global turnarounds and asset optimization schedules. The listed pricing represents a spot-market estimate; contact us for a firm commercial quote.
Frequently Asked Questions
What happens if I connect this module to an AISI 4140 steel target?
Because the 145004-13 modification altered the linear compensation stage, running this unit against standard AISI 4140 steel will cause your digital vibration monitors to report inaccurate, non-linear gap voltages and incorrect dynamic amplitudes.
Can I mix a legacy non-XL 3300 extension cable with this sensor?
Yes. The 3300 XL Proximitor hardware line retains backwards compatibility with non-XL 3300 5-mm and 8-mm extension components. However, the system performance envelope will drop to legacy limits, resulting in higher cross-generation probe interchangeability variances.
