Description
Product Introduction
The 3300 XL 11 mm Proximity Probes measure vibration and position. This model 330709-000-080-50-12-00 comes from Bently Nevada. It works well for turbines, compressors, and pumps. The probe uses a rugged PPS tip and stainless steel case. You get stable data even in harsh conditions.

FAQ – Frequently Asked Questions
- Can I use this probe with a 9m Proximitor? No. Use only with a 5m Proximitor Sensor.
- What happens below -34°C? The pressure seal may fail early.
- Is this probe submersible in oil? No. FluidLoc cable resists oil but not full immersion.
- What is the linear measurement range? About 2 mm (80 mils) for 11 mm tip.
- Do I need a special tool for installation? Only standard torque wrench.
- Experience: The target shaft is smaller than 152 mm. Can I still use it? We do not recommend it. Cross-talk may cause errors.
- Selection guide: Which length should I choose – 5m or 9m? Pick 5m if your Proximitor is 5m. For longer runs, choose 9m probe with 9m Proximitor.
- Selection guide: What thread size fits most machines? M16 x 1.5 is common for large frames. Check your housing first.
- Selection guide: Do I need armor? Without armor (suffix 000) is fine for clean, fixed installations. Use armor if cable may rub or get damaged.
