Frequently Asked Questions (FAQ)

• Is this probe compatible with my existing system? Yes. The 3300 NSv Probes are fully interchangeable with previous Bently Nevada 3300 RAM probes and extension cables.
• What is the main advantage of the NSv design? It provides increased chemical resistance, making it ideal for harsh environments like process compressors.
• Can I use this for axial measurements on a small shaft? For shafts under 13 mm, the scale factor may change. Reducing the probe gap can help minimize this effect.
