Frequently Asked Questions (FAQ)
- Question: What is the maximum cable length for this probe?
Answer: Available in 1, 5, or 9 meters. This model has 1.0 meter.
- Question: Can I use this probe in wet environments?
Answer: Yes if connectors stay dry. Humidity up to 100% condensing is allowed.
- Question: What happens if I exceed 63.3 N•m torque?
Answer: You may strip the threads or damage the probe case.
- Question: Does the probe work with 3300 XL extension cables?
Answer: Yes. Use Bently Nevada approved extension cables only.
- Question: Why does the part number have so many segments?
Answer: Each segment specifies length, connector, and options for custom fit.
Experience-based Q&A (Field Notes)
- Question: My reading drifts slowly over time. What should I check?
Answer: Check probe tip for debris or oil. Also verify cable has no cuts.
- Question: The ClickLoc connector feels loose. Is that normal?
Answer: No. Tighten finger tight only. Overtightening breaks the connector.
- Question: Can I shorten the probe cable?
Answer: No. Shortening changes resistance and calibration. Order correct length.
- Question: We see noise at 60 Hz. How to fix?
Answer: Move probe away from power cables. Shield the cable properly.
Buying Guide – Choose the Right 3300 XL Probe
- Choose 330709-050-120-10-02-00 for M16 thread, 50mm unthreaded, 120mm case, 1m cable.
- Need longer cable? Pick 5m or 9m total length options (digits 13-14).
- For armored cable, select armor option at beginning of part number.
- Check your shaft diameter – minimum 152 mm (6 inches) recommended.
- Verify temperature range. This probe handles up to +177°C.
- Contact us for custom pressure testing before shipment.
