Bently Nevada 24701-28-05-XX-025-04-XX MOD: 323933-30-02 Modified Stainless-Steel Proximity Probe Housing Assembly
A modified 24701 housing assembly with a 3300 XL 8 mm approval-option probe, 0.5 m (20 in) cable and 2.5 in penetration.
Product Profile
Bently Nevada 24701-28-05-XX-025-04-XX MOD: 323933-30-02 is a modified 24701 stainless-steel proximity probe housing assembly. Option 28 identifies a 3300 XL 8 mm probe with selectable hazardous-area approvals, while cable option 05 identifies a 0.5 m (20 in) probe cable.
The submitted standoff and final mounting-thread positions remain XX and are intentionally unresolved. Penetration 025 defines 2.5 in (63.5 mm), fittings option 04 defines one 3/4-14 npt plug only, and the modification record is retained as 323933-30-02.
Technical Data
System Role
The stainless-steel housing combines a threaded dome cover, conduit ports, probe sleeve, O-rings, thread seal and reverse-mount 3300 XL 8 mm probe.
The full ordering string controls cable length, optional standoff, penetration, fittings and mounting-thread selection as one mechanical identity.
The protected housing supports external probe mounting while preserving access for adjustment and service.
A sleeve support is required whenever the selected standoff plus probe-penetration dimension exceeds 300 mm (12 in).
Compatibility & Service
- Record the complete 24701 code, MOD reference, installed standoff, penetration and mounting thread before removal.
- Measure the available machine-case depth and calculate the actual standoff-plus-penetration dimension before ordering.
- Keep the probe lead longer than the sleeve and add approved sleeve support when the 300 mm threshold is exceeded.
- After installation, verify probe gap, cable routing, housing sealing, channel response and the approved alarm or trip test.
Applications
- Externally mounted radial-vibration or shaft-position measurement on rotating machinery.
- Protected probe access on bearing housings where conduit entry and sleeve geometry must be controlled.
- Like-for-like replacement of a documented modified 24701 housing execution.
- Hazardous-area installations only after the complete probe approval option and site drawing have been verified.
FAQ
Q01Why is 323933-30-02 part of the exact 24701-28-05-XX-025-04-XX MOD: 323933-30-02 identity?+
It differentiates this modified supply record from the 00, 35 and 40 executions in the same group and must remain attached to the order string.
Q02Does option 04 on 24701-28-05-XX-025-04-XX MOD: 323933-30-02 include a cable seal grip?+
No. Option 04 is one 3/4-14 NPT plug only, so any additional field fitting must be confirmed separately.
Q03Can the 2.5 in penetration of 24701-28-05-XX-025-04-XX MOD: 323933-30-02 be inferred from the MOD?+
No. It is explicitly defined by the 025 block; MOD 323933-30-02 is retained separately and is not used to decode penetration.
Q04What determines sleeve-support need for 24701-28-05-XX-025-04-XX MOD: 323933-30-02?+
The combined unresolved standoff and 2.5 in penetration must be calculated; support is required only if that total exceeds 12 in.
Q05Which mechanical checks prevent a wrong replacement of 24701-28-05-XX-025-04-XX MOD: 323933-30-02?+
Compare the standoff, mounting thread, penetration, conduit arrangement, target depth and available probe-adjustment range.
