Frequently Asked Questions (FAQ)

• Is the 3300 NSv probe fully compatible with older 3300 RAM systems? Yes – it is mechanically and electrically interchangeable with the previous 3300 RAM probe and extension cable.
• What is the recommended gap setting for this probe? Bently Nevada recommends a gap of 1.0 mm (40 mils) for optimal linear performance.
• Can I use this probe on shafts smaller than 13 mm? Yes, but the scale factor may change. Reducing the gap can help minimize this effect (see Figure 12 in the manual).
• What is the maximum field wiring length? You can run up to 305 meters (1000 feet) of shielded triad cable between the Proximitor Sensor and the monitor.
• Is the probe pressure‑tested before delivery? No, probes are not pressure‑tested. Contact our custom design department if you require a specific pressure seal test.
• What is the operating temperature limit? The probe works from ‑52 °C to +177 °C (‑62 °F to +351 °F), both in operation and storage.
