Frequently asked questions (FAQ)

• What extension cable works with the 330172? Use Bently Nevada 3300 series extension cables with ClickLoc mates. The 9 m probe integrates directly with 3300 XL proximitors.
• Can I use this probe in high‑temperature areas? Yes, the probe alone tolerates –35 °C to +177 °C. Observe temperature class schedules for hazardous areas.
• Is the tip replaceable? No, the PPS tip is factory‑bonded. The 330172-00-20-90-02-00 is a one‑piece assembly.
• What is the linear range for this 5mm probe? Typically 2 mm (80 mils) when used with a –24 Vdc supply and AISI 4140 target.
• Does Ubest Automation provide calibration data? This genuine Bently Nevada probe meets factory specs; calibration certificates available on request.
