Bently Nevada 21000-28-10-0-41-04-02 is a proximity probe housing assembly designed for secure installation of 3300 XL 8 mm proximity probes in industrial rotating machinery monitoring applications. It is widely applied in turbines, compressors, pumps, and heavy-duty process equipment where stable probe positioning is required for accurate vibration and shaft displacement measurement.
This housing system provides a rigid mechanical interface between the probe and machine casing, ensuring consistent probe penetration and alignment under continuous vibration and thermal stress. It supports reliable eddy-current signal generation in condition monitoring systems used for asset protection and predictive maintenance.
The 3/4-14 NPT mounting interface enables standardized integration into industrial machine housings, supporting both OEM installation and retrofit applications in power generation and process industries.

This housing assembly ensures fixed mechanical positioning of proximity probes to maintain measurement accuracy in high-vibration industrial environments. It eliminates installation variability caused by mechanical drift, thermal expansion, and housing deformation.
Probe penetration configuration defines the physical depth relationship between probe tip and target surface, which directly affects signal linearity in eddy-current measurement systems.
The standardized NPT interface simplifies integration into machine housings without requiring custom machining or adapter structures.
Where is this housing used?
It is used in turbines, compressors, pumps, and industrial rotating machinery requiring stable probe installation.
Why is probe penetration important?
It ensures correct gap positioning for accurate vibration signal generation.
Can it be used with non-3300 XL probes?
No. It is designed specifically for Bently Nevada 3300 XL 8 mm probe systems.
What is the benefit of NPT mounting?
It allows standardized and reliable mechanical integration into industrial equipment housings.
Ensure correct torque application during NPT thread installation to prevent misalignment or mechanical stress on housing structure.
Verify probe penetration depth before system commissioning to ensure correct calibration of gap voltage output.
Maintain clean mounting surfaces to avoid debris interference affecting probe alignment and measurement stability.
Route probe cables away from high-voltage conductors and VFD output lines to minimize electromagnetic interference.
Avoid mechanical impact during installation to preserve probe alignment accuracy and housing integrity.
Use appropriate sealing practices on NPT threads to prevent fluid ingress in turbine and compressor environments.
Inspect housing periodically in high-vibration machinery to ensure long-term mechanical stability.
Ensure consistent grounding practices to reduce electrical noise in proximity measurement signals.
