System Compatibility
The 330904-00-06-50-02-00 is designed for use within the Bently Nevada 3300 XL NSv system and is compatible with the following:
- Drivers/Monitors: 3300 XL 11 mm Driver, 3300 XL 8 mm Driver, 3500/42M Proximitor I/O Module
- Monitoring Systems: Bently Nevada 3500 Series Rack, System 1 Software
- Target Materials: AISI 4140 steel (standard); consult factory for non-standard alloys
- Mounting: Standard 3/8-24 UNF thread (probe body)
Selection Guide
Use the following criteria to select the correct proximity transducer system for your application:
- Step 1 — Probe Diameter: 3300 XL NSv uses 8 mm probes. Confirm your existing bracket/bore size.
- Step 2 — Cable Length: The -06 suffix = 6-inch integral cable. Match to your extension cable (5.0 m standard for this model).
- Step 3 — Driver Compatibility: Confirm driver part number. NSv probes require NSv-compatible drivers.
- Step 4 — Target Material: Standard calibration is for AISI 4140. Non-standard alloys require a special calibration factor.
- Step 5 — Environment: Check temperature rating and hazardous area classification (ATEX/FM) for your installation zone.
- Step 6 — Measurement Type: Radial vibration, axial position, or speed? Confirm the correct transducer orientation and mounting.

Replacement & Compatibility FAQ
Q: Can I replace 330904-00-06-50-02-00 with 330903-00-06-50-02-00?
A: Yes, in most cases. Both use the same 200 mV/mil sensitivity and 5.0 m extension cable. Verify the driver part number and gap voltage setting before installation.
Q: Is this probe compatible with the Bently Nevada 3500 rack?
A: Yes, when paired with the correct 3500/42M Proximitor I/O module and NSv-compatible driver.
Q: Can I use an Epro PR6423 as a replacement?
A: Epro probes are cross-brand equivalents but require a different driver and full system recalibration. Not a plug-and-play swap.
Q: What is the target material for standard calibration?
A: AISI 4140 steel. If your shaft is a different alloy, a calibration correction factor must be applied.
Q: Do you provide a certificate of conformance?
A: Yes, available upon request for all orders.
Q: What is the warranty on this product?
A: We offer a 90-day functional warranty on all verified units. OEM warranty terms apply to new, sealed stock.
