Bently Nevada 330103-00-60-05-02-05 – Non-Contact Eddy Current Proximity Probe | 3300 XL 8mm Transducer System
Engineering Background
The Bently Nevada 3300 XL 8mm Proximity Transducer System is the global benchmark for non-contact shaft vibration and position measurement in rotating machinery protection. Developed under Baker Hughes’ Bently Nevada product line, the 330103 series proximity probe is engineered to deliver sub-micron resolution in the harshest industrial environments — from gas turbines and steam turbines to compressors, pumps, and gearboxes.
Product Positioning
The 330103-00-60-05-02-05 is a factory-configured 8mm eddy current proximity probe with a 5-metre (16.4 ft) integral armored cable, designed for direct integration into Bently Nevada 3300 XL signal conditioning systems. It is the preferred choice for OEM machinery builders and reliability engineers who require API 670-compliant vibration monitoring with zero mechanical contact and zero wear.

- High-Temperature Probe Tip – Rated to +177°C for direct bearing housing mounting
- Plug-and-Play with 3300 XL Ecosystem – Matched scale factor ensures system accuracy without field adjustment
System Architecture & Signal Flow
The 330103-00-60-05-02-05 operates as the sensing element in a three-component eddy current transducer system:
- Proximity Probe (330103) → Generates high-frequency electromagnetic field at tip; detects conductive target displacement
- Extension Cable (330130) → Transmits RF signal from probe to Proximitor with matched impedance (if required for distances >5 m)
- Proximitor Sensor (330180) → Demodulates RF signal; outputs calibrated DC voltage proportional to gap distance
Output signal: –24 VDC supply in → –10 VDC bias output at nominal 1.27 mm gap → linear voltage swing across 0.25–2.26 mm measurement range. Signal feeds directly to Bently Nevada 3500 Series rack monitors or any API 670-compliant vibration monitor.

Technical FAQ
Q: Is the 330103-00-60-05-02-05 compatible with the Bently Nevada 3500 rack?
A: Yes. When paired with a 330180 Proximitor Sensor, the output signal is fully compatible with all 3500 Series monitor cards (3500/40M, 3500/42M, 3500/45, etc.).
Q: What does the part number suffix -00-60-05-02-05 indicate?
A: The suffix encodes: probe body style (00), cable length in decimeters (60 = 6.0 m integral), connector type (05), target material code (02), and temperature rating code (05). Always verify with the Bently Nevada 330103 datasheet for your specific revision.
Q: Can this probe measure non-ferrous targets?
A: The 330103 is calibrated for AISI 4140 steel. Non-ferrous targets (aluminum, titanium, Inconel) will produce a different scale factor and require recalibration via the Proximitor trim potentiometer.
Q: What is the difference between 330103 and 330104?
A: The 330103 uses an integral (non-separable) cable, while the 330104 uses a field-replaceable connector. The 330103 is preferred for permanent installations; the 330104 for applications requiring periodic probe replacement without cable re-routing.
Q: Do you provide ATEX/IECEx certified versions?
A: Yes. Bently Nevada offers ATEX-certified variants of the 3300 XL system. Please specify your hazardous area classification (Zone 1/Zone 2) when requesting a quote.
