Bently Nevada 24701-28-05-XX-015-04-XX MOD: 323933-35-02 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 1.5 in penetration.
Overview
Bently Nevada 24701-28-05-XX-015-04-XX MOD: 323933-35-02 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 015 defines 1.5 in (38.1 mm), fittings option 04 defines one 3/4-14 npt plug only, and the modification record is retained as 323933-35-02.
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
Why must the XX positions remain in 24701-28-05-XX-015-04-XX MOD: 323933-35-02?
They represent configuration positions that are not resolved by the submitted identity. Replacing them with assumed standoff or thread values could change mechanical fit.
Does the 1.5 in penetration on 24701-28-05-XX-015-04-XX MOD: 323933-35-02 need a machine-case counterbore?
Bently Nevada notes that penetrations between 1.0 and 2.0 in may require a counterbore to reduce side-view or rear-view effects. Confirm the machine geometry for 24701-28-05-XX-015-04-XX MOD: 323933-35-02 before installation.
What distinguishes fittings option 04 on 24701-28-05-XX-015-04-XX MOD: 323933-35-02?
Option 04 supplies one 3/4-14 NPT plug only; it does not include the reducer and cable seal grip provided by option 03.
What evidence should accompany an enquiry for 24701-28-05-XX-015-04-XX MOD: 323933-35-02?
Provide the complete label, MOD 323933-35-02 record, machine mounting thread, measured standoff, target depth, conduit arrangement and approval requirements.
How should 24701-28-05-XX-015-04-XX MOD: 323933-35-02 be accepted after installation?
Confirm its short-reach mechanical clearance, electrical gap, stable static output, dynamic channel response and the approved alarm or protection check.
