Frequently Asked Questions (FAQ)
- Can I use this housing with an older 7200 series probe?No, it is specifically designed for 3300 XL 8 mm reverse-mount probes. Using other probes may not seal or fit correctly.
- What does “probe penetration 3.1 in” mean for installation?It sets how far the probe tip extends from the housing face. This 031 option is preset; you cannot adjust it in the field.
- Is the probe cable replaceable if damaged?The probe and cable are integral. You must replace the entire assembly if the cable breaks. Order the 24701-proximity-probe with same suffix.
- Do I need to order the probe separately?No. Suffix “34” means the 3300 XL 8 mm probe is already included inside the housing.
- Which conduit fitting is supplied?Option 04 provides one 3/4-14 NPT plug. You can add your own conduit connector or use this plug to seal the port.
Selection Guide
- Need a different probe cable length? Suffix 05 = 0.5 m. For longer cables, choose a different option (e.g., 10 for 1.0 m).
- Require a standoff adapter? This unit is 00 = none. Contact us if you need one.
- For hazardous locations, suffix 34 includes a probe with selectable approvals – verify with your area classification.
- Always confirm mounting thread: 02 = 3/4-14 NPT. Other thread options available upon request.

Kevin Martinez –
We needed a new proximity probe housing assembly for a 3300 XL system. This unit arrived in perfect condition and was clearly unused. Fit and finish were excellent, and installation on-site was smooth. It’s currently supporting vibration monitoring on a critical compressor. PowerGearX shipped fast and answered all technical questions promptly. Very reliable source for genuine Bently Nevada components.
