Bently Nevada 330103-12-16-10-02-05 Proximity Probe | Eddy Current Vibration Sensor | 3300 XL Series
Engineering Background
The Bently Nevada 3300 XL proximity transducer system is the industry benchmark for continuous, non-contact measurement of shaft radial vibration, axial position, differential expansion, and eccentricity on rotating machinery. Deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide, the 3300 XL platform is fully compliant with API 670 machinery protection standards.
Product Positioning
The 330103-12-16-10-02-05 is an 8mm diameter eddy current proximity probe engineered for high-resolution, real-time shaft displacement measurement. With a 5-metre (16 ft) integral cable, a 10mm linear range, and a standard -24 VDC supply, this probe integrates directly into Bently Nevada 3300 XL monitor racks without additional signal conditioning. It is the preferred choice for procurement engineers specifying API 670-compliant machinery protection systems on critical rotating assets.

Proven Application Environments
- Power Generation: Steam turbines, gas turbines, hydro generators — continuous shaft vibration and axial position monitoring per API 670.
- Oil & Gas: Compressor trains, centrifugal pumps, expanders — upstream, midstream, and downstream critical machinery protection.
- Petrochemical & Refining: Reactor agitators, blowers, and high-speed rotating equipment in hazardous area classifications.
- Pulp & Paper / Steel Mills: Large induction motors, gearboxes, and rolling mill drives requiring continuous eccentricity monitoring.
- Marine & Offshore: Propulsion shafting and auxiliary machinery on FPSO and offshore platform installations.
Engineering Advantages
- Non-Contact Measurement: Zero mechanical wear; suitable for continuous 24/7 operation on critical assets.
- High Bandwidth (DC–10 kHz): Captures both slow-roll runout and high-frequency vibration components in a single channel.
- API 670 Native Compatibility: Direct plug-in to 3300 XL monitor racks — no additional signal conditioning or scaling required.
- 316L SS Body + PTFE Cable: Resistant to process fluids, steam, and aggressive chemical environments.
- IP67 Sealing: Suitable for wash-down and high-humidity installations without additional enclosure.
- Integral 5 m Cable: Eliminates field-spliced connections; reduces installation error and signal noise.
System Architecture & Signal Flow
The 330103-12-16-10-02-05 operates as part of the Bently Nevada 3300 XL three-component transducer system:
- Proximity Probe (330103-xx-xx-xx-xx-xx): Generates a high-frequency electromagnetic field; detects eddy-current-induced impedance changes in the target shaft surface.
- Extension Cable (330130-xx-xx-xx): Transmits the raw oscillator/demodulator signal from probe to driver; total system cable length must match driver calibration.
- Proximitor® Driver / Oscillator-Demodulator (3300 XL series): Converts impedance change to a calibrated DC voltage output (−2 V to −18 V); feeds 3500 or 3300 monitor rack.
- Monitor Rack (3500/3300 series): Processes voltage signal into engineering units (µm or mil); triggers alarms and trips per API 670 setpoints.
Note: Total combined cable length (probe integral cable + extension cable) must equal the driver’s rated system length. Verify compatibility before ordering extension cables.

Technical FAQ
Q: Is the 330103-12-16-10-02-05 compatible with the Bently Nevada 3500 monitor rack?
A: Yes. The 3300 XL probe system is fully compatible with both 3300 and 3500 series monitor racks when paired with the correct Proximitor® driver and matching system cable length.
Q: What is the difference between the -02-05 and -02-00 suffix?
A: The suffix encodes connector and approval options. -02-05 denotes a standard BNC connector with specific agency approvals. Consult the Bently Nevada 330103 datasheet or contact Konmask for cross-reference assistance.
Q: Can this probe be used on non-ferromagnetic targets (e.g., titanium, aluminum)?
A: No. The standard 330103 probe is calibrated for steel/iron targets. Non-ferromagnetic target applications require a specially calibrated probe — contact Bently Nevada or Konmask for alternatives.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume discounts available for orders of 5+ units.
Q: Do you provide ATEX / IECEx certification documentation?
A: Yes, upon request. Please specify your hazardous area classification when inquiring.
