Bently Nevada 330104-00-10-05-01-05 – Eddy Current Proximity Probe | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for non-contacting eddy current measurement systems, engineered specifically for continuous machinery protection and condition monitoring in critical rotating equipment. The 330104-00-10-05-01-05 is an 8 mm diameter proximity probe designed to deliver sub-micron resolution displacement measurements in the harshest industrial environments.
Product Positioning
This probe is the primary sensing element in a complete 3300 XL transducer system (probe + extension cable + proximitor). It is specified by OEM turbine builders, compressor OEMs, and reliability engineers worldwide as the standard for API 670-compliant machinery protection systems. Konmask.com supplies this part as a verified OEM component with full traceability documentation available upon request.

System Architecture & Signal Flow
The 330104-00-10-05-01-05 probe operates as part of a three-component transducer chain:
- Proximity Probe (this unit) – Generates an oscillating electromagnetic field; eddy currents induced in the target shaft modulate the field proportional to gap distance.
- Extension Cable – Transmits the high-frequency carrier signal from probe tip to Proximitor with minimal loss (matched impedance, 3300 XL series cables required).
- Proximitor / Seismic Monitor – Demodulates the carrier, outputs a DC-proportional voltage (–24 VDC supply, –24 VDC to 0 VDC output range) to the monitoring rack or DCS/PLC input card.
Output signal is directly compatible with Bently Nevada 3500 Series rack monitors, 1900/65 machinery protection monitors, and third-party 4–20 mA converters.

Technical FAQ
Q: Is this probe compatible with the Bently Nevada 3500 Series monitoring rack?
A: Yes. The 3300 XL probe system (probe + extension cable + Proximitor) outputs a standard –24 VDC proportional signal fully compatible with 3500 Series input modules.
Q: Can this probe be used with non-steel target materials?
A: The standard calibration is optimized for AISI 4140 steel. Use with other alloys (titanium, Inconel, aluminum) requires a material-specific calibration curve. Contact Konmask for recalibration support.
Q: What extension cable is required?
A: The -05- suffix in the part number designates a 5-meter extension cable requirement. Compatible cables include the Bently Nevada 330130 series (3300 XL, 5 m).
Q: What is the lead time for this part?
A: In-stock units ship within 3–5 business days. Out-of-stock lead time is typically 4–8 weeks. Contact us for real-time availability.
Q: Do you provide installation and commissioning support?
A: Konmask provides remote technical guidance for installation, gap setting, and system commissioning. On-site support can be arranged for large projects.
