Bently Nevada 24701-28-10-XX-149-03-XX MOD: 323933-00-02 Modified Stainless-Steel Proximity Probe Housing Assembly
A modified 24701 housing assembly with a 3300 XL 8 mm approval-option probe, 1.0 m (39 in) cable and 14.9 in penetration.
Overview
Bently Nevada 24701-28-10-XX-149-03-XX MOD: 323933-00-02 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 10 identifies a 1.0 m (39 in) probe cable.
The submitted standoff and final mounting-thread positions remain XX and are intentionally unresolved. Penetration 149 defines 14.9 in (378.5 mm), fittings option 03 defines one 3/4-14 npt plug, one 3/4-14 to 1/2-14 npt reducer and one cable seal grip with three grommet ranges, and the modification record is retained as 323933-00-02.
Engineering Data
Functions
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).
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.
Lifecycle & 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.
FAQ
Is sleeve support optional for 24701-28-10-XX-149-03-XX MOD: 323933-00-02?
No. The 14.9 in penetration already exceeds 300 mm, so the manufacturer requires support near the probe to prevent sleeve resonance.
Why is the 1.0 m cable important on 24701-28-10-XX-149-03-XX MOD: 323933-00-02?
The 10 option identifies a 1.0 m probe cable and permits a larger documented C plus D envelope than the 0.5 m option. It must remain matched to the installed system.
What combined standoff-and-penetration limit applies to 24701-28-10-XX-149-03-XX MOD: 323933-00-02?
The published maximum C plus D dimension for the 24701 housing with a 1.0 m cable is 742 mm (29.2 in).
What long-sleeve installation evidence is needed for 24701-28-10-XX-149-03-XX MOD: 323933-00-02?
Provide the sleeve-support location, machine-case depth, available internal clearance, target position, conduit route and final probe-gap record.
Can a 0.5 m cable variant replace 24701-28-10-XX-149-03-XX MOD: 323933-00-02?
Not from the family number alone. Its cable length changes the permitted mechanical envelope and the complete transducer-system length must remain correct.
