Provides a protective housing for the probe connection and field conduit entry.
Technical Summary
24701-28-05-00-070-04-02 is a Bently Nevada 24701 proximity probe housing assembly configured for a 3300 XL 8 mm probe with approval option.
The ordering string defines a 20 in (0.5 m) probe cable, no standoff adapter, 7.0 in probe penetration, one 3/4-14 NPT plug and a 3/4-14 NPT mounting thread.
The complete suffix is part of the mechanical fit. Probe family, penetration, conduit entry and mounting thread must all match the installed housing record.

Features
Keeps the probe family, cable length, penetration and mounting thread in one traceable ordering number.
Uses a defined 7.0 in penetration rather than a field-estimated insertion depth.
Includes one 3/4-14 NPT plug for the stated conduit arrangement.
Compatibility
- Match the 3300 XL 8 mm probe option and the complete transducer-system electrical length.
- Verify that the machine mounting port is 3/4-14 NPT and that the 7.0 in penetration suits the target geometry.
- Confirm enclosure clearance, conduit orientation and access for probe adjustment before installation.
- Do not substitute a 21000 housing or another 24701 suffix without comparing every ordering-code position.
Replacement
- Record the old housing label, probe gap, penetration reference and conduit orientation before removal.
- Isolate the monitored machine and protection system in accordance with the approved maintenance procedure.
- Install the exact housing thread without transferring mechanical load to the probe cable.
- Set probe gap and verify the full vibration-monitoring channel before returning protection functions to service.
FAQ
What field evidence should accompany a 24701-28-05-00-070-04-02 enquiry?
Provide the complete housing label, mounting-port photograph, target geometry, installed probe and extension-cable identities, and conduit orientation.
Can a different penetration code be used if the mounting thread matches?
Only after an engineering check of target position, adjustment range and machine clearance; the 070 penetration is part of the ordered geometry.
When is sleeve support relevant to a 24701 housing installation?
Bently Nevada calls for sleeve support when combined probe penetration and standoff exceed 300 mm; calculate the complete installed geometry rather than the housing code alone.
Should the probe be regapped after replacing the housing?
Yes. Mechanical replacement changes the probe position, so gap voltage and the complete channel response must be checked.
What confirms 24701-28-05-00-070-04-02 is ready for service?
The housing must be secure, conduit sealed, probe gap stable and the monitor channel verified through the approved functional test.
