Bently Nevada 330104-00-15-10-01-05 – 8mm Eddy Current Proximity Probe | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for continuous shaft vibration and position monitoring in rotating machinery. Developed by Baker Hughes (Bently Nevada), this eddy current-based measurement system has been deployed across power generation, oil & gas, and petrochemical industries for decades, providing the real-time data that machinery protection systems depend on.
Product Positioning
The 330104-00-15-10-01-05 is an 8mm diameter proximity probe engineered for the 3300 XL system architecture. It delivers non-contact, continuous measurement of shaft radial vibration, axial position, and differential expansion — critical parameters for API 670-compliant machinery protection. This probe is the primary sensing element in a three-component measurement chain: probe → extension cable → proximitor/driver.

- Hydro Turbines – Axial and radial displacement in wet environments
- Reciprocating Compressors – Rider band wear and crosshead monitoring
Engineering Advantages
- Non-contact measurement – Zero mechanical wear; suitable for continuous 24/7 operation
- Wide frequency bandwidth – DC to 10 kHz captures sub-synchronous, synchronous, and high-frequency events
- High temperature tolerance – Rated to +177°C for hot-section turbine bearing housings
- IP67 sealing – Resistant to oil mist, steam, and washdown environments
- 316 SS housing – Corrosion-resistant for offshore and chemical plant installations
- Direct 3300 XL compatibility – Plug-and-play with existing 3300 XL Proximitor drivers; no recalibration required for standard steel targets
System Architecture & Signal Flow
The 330104-00-15-10-01-05 operates as the sensing element in the Bently Nevada 3300 XL measurement chain:
- Probe (330104-00-15-10-01-05) – Generates eddy current field; outputs raw oscillator signal via integral 5m cable
- Extension Cable – Connects probe to proximitor (total system cable length must match proximitor calibration)
- 3300 XL Proximitor / Driver (e.g., 330180) – Conditions signal; outputs –24 VDC bias and calibrated voltage proportional to gap distance
- Monitoring System (e.g., 3500 Rack) – Receives 4–20 mA or voltage signal for alarm, trip, and trending
Note: Total cable length (probe integral + extension) must be specified at time of order to ensure factory calibration match with the designated proximitor.

Technical FAQ
Q: Is this probe compatible with the older 3300 (non-XL) system?
A: The 3300 XL probes use the same physical connector and cable standard as the legacy 3300 series, but scale factors and calibration may differ. Verify your proximitor model before mixing series components.
Q: What target material is this probe calibrated for?
A: Factory calibration is for AISI 4140 steel. For other alloys (e.g., Inconel, titanium), a material correction factor or field recalibration is required — consult Bently Nevada Application Note AN028.
Q: Can I use a longer extension cable?
A: Yes, but total system cable length (probe integral + extension) must match the proximitor’s calibrated length. Mismatched lengths introduce scale factor error. Contact us to confirm the correct extension cable part number.
Q: Do you provide a warranty?
A: Konmask offers a 90-day functional warranty on all units. New OEM units carry the full Baker Hughes factory warranty.
Q: What is the lead time?
A: In-stock units ship within 2–5 business days. For out-of-stock items, typical lead time is 2–4 weeks. Contact us for real-time availability.
