Bently Nevada 330103-00-15-50-02-CN – Eddy Current Proximity Transducer System | 3300 XL Series
Engineering Background
The Bently Nevada 3300 XL 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 is deployed globally in turbines, compressors, pumps, and generators where measurement integrity is non-negotiable.
Product Positioning
Part number 330103-00-15-50-02-CN is a factory-configured transducer assembly comprising a 5 mm tip-diameter probe, 5-metre (15 ft) integral cable, and 2-metre (50 cm) extension cable, calibrated for standard Bently Nevada driver/monitor compatibility. The -CN suffix denotes CE/China-market compliance marking. This unit is a direct OEM replacement for existing 3300 XL installations and is fully interchangeable with Bently Nevada 3500 series monitoring racks.

- CE / CN marking — Compliant for import and installation in China and EU markets
System Architecture & Signal Flow
The 330103-00-15-50-02-CN operates as a three-component eddy current system:
- Probe (330103) — Generates a high-frequency electromagnetic field at the tip; eddy currents induced in the target shaft modulate the field proportionally to gap distance.
- Extension Cable (330130 / included) — Low-loss coaxial cable transmits the modulated RF signal from the probe to the driver with minimal attenuation.
- Driver / Oscillator-Demodulator — Converts the RF signal to a DC voltage output (–2 V to –18 V); connects directly to Bently Nevada 3300 or 3500 monitor input cards.
Note: Driver/monitor card sold separately. Compatible drivers: Bently Nevada 330180, 330185, 330190 series.

Technical FAQ
Q: Is this a genuine Bently Nevada OEM part?
A: Yes. All units are sourced from OEM or authorized surplus channels. Documentation available on request.
Q: Can I use this with a Bently Nevada 3500 rack?
A: Yes. The 330103 probe is fully compatible with 3500 series monitor cards when paired with the appropriate driver (e.g., 330180).
Q: What is the target material requirement?
A: Standard calibration is for AISI 4140 steel. For stainless steel, Inconel, or other alloys, a material correction factor must be applied — contact us for recalibration options.
Q: Does the -CN suffix affect performance?
A: No. The -CN suffix indicates CE/China compliance marking only. Electrical and mechanical specifications are identical to the standard version.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. For bulk orders or specific serial number requirements, please inquire.
