System Compatibility
The 330904-00-15-50-02-00 is designed to operate as part of the Bently Nevada 3300 XL NSv system, which includes:
- Probe: 330904-xx-xx-xx-xx-xx series (8 mm tip)
- Extension Cable: 330130-xx-xx (matched impedance coaxial)
- Driver / Proximitor: 330180-x1-00 or 330180-x0-00 (3300 XL Proximitor)
- Monitor: Bently Nevada 3500/40M, 3500/42M, or 3300 series rack monitors
This transducer is not directly interchangeable with 5 mm or 14 mm probe systems without driver reconfiguration. Confirm your existing Proximitor model before ordering.
Selection Guide
Use the following criteria to select the correct part number suffix for your application:
| Parameter | Code Position | Options |
|---|---|---|
| Cable Length | 3rd segment | 03 = 3 m, 05 = 5 m, 09 = 9 m |
| Probe Tip | 4th segment | 50 = standard 8 mm tip |
| Connector | 5th segment | 02 = standard MIL connector |
| Target Material | 6th segment | 00 = AISI 4140 steel (standard) |
For non-standard target materials (Inconel, titanium, stainless), request a target material correction factor from our technical team.

Replacement & Compatibility FAQ
Q: Can I use the 330904-00-15-50-02-00 with a 3500 series monitor?
A: Yes, when paired with the correct 3300 XL Proximitor driver (330180 series), it is compatible with Bently Nevada 3500/40M and 3500/42M monitor cards.
Q: Is the Epro PR6423 a direct drop-in replacement?
A: Functionally equivalent in most installations. Mechanical dimensions and sensitivity are matched, but verify connector pinout and driver calibration range before substitution.
Q: What is the difference between 330904 and 330903?
A: The primary difference is cable length — 330903 uses a 3 m extension cable; 330904 uses 5 m. All other electrical parameters are identical.
Q: Can this probe measure non-ferrous targets?
A: Standard calibration is for AISI 4140 steel. For non-ferrous or exotic alloy targets, a target material correction factor must be applied. Contact us for details.
Q: Do you provide ATEX-certified units?
A: Yes, ATEX/IECEx certified configurations are available. Please specify your hazardous area zone when requesting a quote.
