❓ FAQ –Experience-based Q&A & Purchase Guide
- Q: Can I use this probe with an old 3300 rack?
- A: Yes. It mates with any 3300/3300 XL proximitor. Ensure extension cable type is 75Ω triaxial.
- Q: What is the maximum cable length between probe and proximitor?
- A: Total extension + probe cable up to 9 meters (system dependent). This probe has 1m cable; add 3300 series extension cables.
- Q: My environment exceeds 177°C. What do I do?
- A: This probe is rated 177°C max. For higher temps, consider high-temperature probes or consult factory.
- Q: Which thread type is used – is it compatible with existing holes?
- A: Standard 1/4-28 UNF. Industry common for 5mm Proximity Probes. Check thread engagement depth ≤0.375″.
- Q: Do I need a special tool to tighten the ClickLoc connector?
- A: No. Hand-tighten plus 1/16 turn. Use torque wrench only on probe case (max 7.3 N·m).
- Q: Purchase Guide– 330171 vs 330173, which one to pick?
- A: Choose 330171 (this model) for standard unarmored, 1m cable needs. 330173 series usually include armor or different connector. Compare below.
🔎 Compare with similar Bently Nevada 3300 5mm probes
- 330171-00-28-10-01-05 (this product) – 1/4-28 thread, unarmored, 1m cable, ClickLoc, multiple approvals.
- 330173-00-09-10-02-CN – armored version? Different options, 09 case length, 02 connector. Verify if armor needed for your application.
- 330173-00-02-10-02-CN – 1/4-28, 1m, but 02 case length, different connector; usually for Chinese market variant. Confirm connector compatibility.
- Purchase Guide: Choose 330171 if you need standard miniature ClickLoc (01) and multiple approvals (05). Choose 330173 series if your system specifies armor or specific agency option “CN”.
