Frequently Asked Questions
Is this probe really genuine Bently Nevada?
Yes, absolutely. We supply only authentic Bently Nevada products. Each probe comes in original factory sealed packaging.
Will this work with my older 3300 system?
Yes. The NSv probe directly replaces the older RAM version. No wiring changes or adapters needed.
What’s the most common installation mistake?
Over-tightening the probe. Use only finger tight force. Maximum torque is very low at 0.56 N•m.
Can I use this on a small motor shaft?
For shafts under 13 mm diameter, you may need special calibration. Reduce the gap slightly for better results.
How do I connect the ClickLoc connector?
Push until it clicks, then tighten the coupling nut. Use a torque wrench for 7.5 N•m connection.
Do you have longer cable versions?
Yes. Standard lengths include 0.5m (this model), 1m, 5m, and 7m. Contact us for other options.
Is pressure testing available?
Standard probes are not pressure tested. For certified pressure seals, contact Bently Nevada custom design.
My wiring run is very long. Any issues?
Keep field wiring under 305 meters. Use quality shielded cable. Signal may roll off at high frequencies over long distances.
Buying Guide & Selection Tips
- Match the part number exactly for replacement
- Verify thread size is M10x1 for your application
- Choose cable length based on machine layout
- Select NSv for better chemical resistance
- Order matching extension cables if needed
