Where This Product Is Used
The Bently Nevada 330103-10-12-05-11-05 Proximity Transducer System is engineered for continuous, non-contact measurement of shaft radial vibration, axial position, and differential expansion in rotating machinery. It is widely deployed in:
- Steam & Gas Turbines – Real-time shaft orbit and eccentricity monitoring to prevent catastrophic failure
- Centrifugal Compressors – Radial vibration surveillance on high-speed impeller shafts in oil & gas processing
- Boiler Feed Pumps – Axial position monitoring to detect thrust bearing wear in power generation plants
- Gearboxes & Expanders – Differential expansion measurement during thermal transients
- Petrochemical & Refinery Trains – API 670-compliant machinery protection on critical rotating assets

Application-Specific FAQ
Q: Can the 330103-10-12-05-11-05 replace an older 330103-10-12-05-02-05 probe?
A: Yes. The -11- driver code denotes the 3300 XL Proximitor® version. It is backward-compatible with 3300 series monitors when the correct Proximitor® is used. Verify the monitor firmware revision supports XL probes.
Q: What shaft materials require a calibration correction factor?
A: The probe is factory-calibrated for AISI 4140 steel. Stainless steel (316L), Inconel, and titanium shafts require a correction factor per Bently Nevada TIL-073. Contact us for the correction curve data sheet.
Q: Is this probe suitable for hydrogen-cooled generators?
A: Yes, provided the ATEX/IECEx variant is specified. Confirm the Proximitor® barrier rating matches the hydrogen zone classification (typically Zone 1, IIC, T4).
Q: What is the maximum allowable runout for accurate vibration readings?
A: Bently Nevada recommends total indicated runout (TIR) ≤ 0.25 mil (6.35 µm) for the target area to avoid mechanical runout masking true vibration amplitude.
Q: Can Konmask provide a calibration certificate with the unit?
A: Yes. A calibration certificate traceable to NIST/NPL standards is available upon request at time of order.
