Bently Nevada 330103-00-07-10-12-05 – Eddy Current Proximity Transducer | 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 motors where real-time rotor dynamic data is mission-critical.
Product Positioning: The 330103-00-07-10-12-05 is a complete eddy-current transducer assembly configured with a 5 mm probe tip, 5-metre integral cable, and 8 mm driver extension. It is the preferred choice for procurement engineers specifying vibration monitoring on high-speed rotating equipment in oil & gas, power generation, and petrochemical facilities.

Engineering Advantages
- API 670 Compliant: Meets the most stringent machinery protection standard for critical rotating equipment.
- Non-Contact Measurement: Zero mechanical wear; continuous operation without maintenance intervals.
- High Frequency Response: DC to 10 kHz bandwidth captures sub-synchronous, synchronous, and high-frequency rotor events.
- Temperature Stability: Calibrated for consistent scale factor across the full operating temperature range.
- Integral Cable Design: Eliminates field-assembly errors; factory-matched probe and cable for guaranteed performance.
- Drop-in Replacement: Direct form-fit-function replacement for existing 3300 XL installations — no re-calibration of the monitoring system required.
System Architecture & Signal Flow
The 330103-00-07-10-12-05 operates as part of the Bently Nevada 3300 XL three-component system:
- Probe (330103 series): Senses rotor position via eddy-current field; integral 5 m cable transmits raw signal.
- Extension Cable (330130 series, if required): Extends total cable length to system specification.
- Proximitor® Driver (330180 series): Conditions the signal and outputs a calibrated –18 VDC linear voltage to the monitoring rack (e.g., 3500 series).
The output feeds directly into Bently Nevada 3500/40M, 3500/42M, or equivalent vibration monitor modules for alarm, trip, and trending functions.

Technical FAQ
Q: Is this a direct replacement for the older 330103-00-07-10-02-05?
A: Yes. The 330103-00-07-10-12-05 is the current revision and is a drop-in replacement with identical mounting dimensions and electrical interface.
Q: Can this probe be used with non-Bently Nevada monitors?
A: The –18 VDC output is compatible with any monitor accepting a standard eddy-current transducer input. Verify scale factor (7.87 V/mm) matches your monitor’s input configuration.
Q: What target material correction is needed for Inconel or titanium shafts?
A: A target material correction factor must be applied. Contact our technical team with your shaft alloy specification for the appropriate calibration data.
Q: Do you supply the matching Proximitor driver?
A: Yes. The compatible driver is the Bently Nevada 330180-X1-05. Please request a matched system quote if required.
Q: Is a calibration certificate included?
A: A certificate of conformance is included as standard. NIST-traceable calibration certificates are available upon request at additional cost.
