STAINLESS STEEL SENSOR HOUSING
Compact external probe mounting for rotating machinery
This configured 24701 assembly combines a stainless steel external housing, adjustable sleeve and reverse-mount 3300 XL 8 mm probe. The order code specifies a 0.5 m probe lead, 2.5 in probe penetration, fitting option 04 and factory modification 323933-30-02.
ROBUST BODY
303 stainless steel housing with 304 stainless steel sleeve.
COMPACT PENETRATION
The 2.5 in penetration option supports shorter machine-case access paths.
CONTROLLED ASSEMBLY
The special XX tokens and MOD identifier must remain matched to the installation drawing.

Applications

APPLICATION CONTEXT
Functions and field value
Verified family capabilities and model-specific configuration
Turbine and compressor bearings
Provides a serviceable external mounting point for proximity measurements at fluid-film bearing machines.
Pumps and motors
Protects the probe connection and supports repeatable adjustment where the machine case remains accessible.
Short access geometry
The 2.5 in penetration option suits installations where the sensing surface is relatively close to the external housing.
Industrial environments
Stainless construction, seals and conduit provisions protect the probe assembly while retaining field access.

Installation

FIELD WORKFLOW
Installation sequence and checks
01
Verify the complete order code
Match the probe option, 0.5 m lead, special C and F tokens, 2.5 in penetration, fitting 04 and MOD 323933-30-02.
02
Confirm machine geometry
Compare the machine-case port, standoff requirement and sleeve path with the controlled installation drawing.
03
Set sleeve and probe position
Maintain correct probe tip reach and ensure the probe lead remains longer than the complete sleeve path.
04
Seal and verify the signal
Install the specified plug, route the cable safely, set the probe gap and confirm the 3300 XL system response.

FAQ

BUYER AND ENGINEER CHECKLIST
Six practical questions before purchase
24701-28-05-XX-025-04-XX MOD:323933-30-02
1. How is this exact housing identified?
Check that 24701-28-05-XX-025-04-XX MOD:323933-30-02 appears in full. Verify penetration 025 and fitting 04 rather than accepting a generic 24701 label.
2. How can buyers identify previous installation?
Request close photos of the sleeve, probe tip, cable entry, threads and cover. Tool marks, seal compression, contamination or cable wear may indicate prior service.
3. How should a supplier be screened?
Match the company identity, quotation, invoice and beneficiary; require current photos of the complete configured assembly and a written discrepancy process.
4. What must engineers measure before ordering?
Confirm the 2.5 in penetration, machine-case port, special standoff geometry, sleeve route, 0.5 m lead and the single 3/4-14 NPT plug arrangement.
5. What proof should be collected before payment?
Obtain dated whole-assembly photos, readable model and MOD identification, probe-tip and connector views, fitting contents and agreed packing or inspection evidence.
6. Can the 025 or 04 options be changed?
Only after engineering review. Penetration changes probe reach, while the fitting option changes the conduit interface and supplied hardware.
