Frequently Asked Questions

• Q: What does the -05 unthreaded length option mean?
• A: This 330904-05-14-05-02-00 includes 50 mm of smooth shaft before threads begin.
• Q: Can I use this probe with my existing Bently Nevada monitor?
• A: Yes. This 3300 NSv probe is compatible with all 3300 XL NSv Proximitor Sensors.
• Q: What is the correct gap setting for this probe?
• A: Bently Nevada recommends a 1.0 mm (40 mils) initial gap.
• Q: Does this probe require an extension cable?
• A: No. The 0.5m integrated cable connects directly to the Proximitor.
• Q: What is the benefit of the 50 mm unthreaded section?
• A: It provides greater flexibility for probe mounting in tight spaces.
