Description
Product Overview
The Bently Nevada 330103-00-14-10-01-00 is a 3300 XL 8 mm Proximity Probe. This device measures radial vibration and position in rotating machinery. Specifically, this model uses a M10 x 1 thread without armor. Its total length reaches 1.0 meter (3.3 feet), and it includes a miniature coaxial ClickLoc connector. Meanwhile, the probe tip employs Polyphenylene sulfide (PPS), while the case uses AISI 303 or 304 stainless steel. Consequently, it works reliably even in harsh industrial environments.

FAQ – Frequently Asked Questions
1. Can I use this probe in a high-humidity area?
Yes. It passes 93% humidity test for 56 days with less than 3% scale factor change.
2. What happens if I tighten past the max torque?
You may strip threads or damage the probe case. Always stay within 33.9 N•m max.
3. How do I check if my probe is working?
Measure DC resistance across center to outer conductor. Expected value: 7.59 ± 0.50 Ω.
4. Does this probe work with non-Bently monitors?
Only if the monitor accepts –1 to –17 Vdc output and matches 3300 XL scale factors.
5. What is the most common mistake when installing?
Using too much torque on the first three threads. Use only 7.5 N•m (66 in•lbf) there.
6. Which probe should I buy for high temperature above +177°C?
Choose the extended temperature range version (up to +218°C tip). This standard version works to +177°C.
7. My site is Zone 2 gas. Is this probe approved?
Yes, with non-incendive connection per drawing 140979 (nA/ec marking).
Selection Guide – Which 3300 XL Probe Do You Need?
Need standard 8mm for most turbines? Choose 330103-00-14-10-01-00 (1m cable, ClickLoc)
Need longer cable? Change Total Length Option (e.g., 20 = 2.0m)
Need armor against physical damage? Select an armored version (not this model)
Need high temperature >177°C? Choose extended temp option (contact sales)
Need agency approval for Europe? Add agency option (not “00”)
Need 11 mm probe for larger gap range? See the 3300 XL 11 mm series
Pro tip from field engineers: Always order one spare probe per machine train. Store at room temperature. Check O-ring before first installation.
