Product Overview
Bently Nevada 24701-16-05-00-073-04-02 is a proximity probe housing assembly designed for secure installation of 3300 XL 8 mm proximity probes in rotating machinery monitoring applications. It is widely applied in turbines, compressors, pumps, and industrial drivetrains where stable probe positioning is required for accurate vibration and shaft displacement measurement.
This housing assembly provides a mechanically stable interface between the probe and machine casing. It ensures consistent probe penetration depth and alignment, which directly affects signal accuracy in eddy-current measurement systems. The configuration supports harsh industrial environments where vibration, thermal expansion, and mechanical stress are continuous operating conditions.
The 3/4-14 NPT mounting interface ensures compatibility with standard industrial threaded ports, making it suitable for both OEM installations and retrofit monitoring upgrades.

Engineering Interpretation Notes
This housing assembly ensures fixed mechanical positioning of proximity probes in applications where probe stability directly affects measurement accuracy. It is designed to eliminate installation drift caused by vibration or thermal expansion in machinery environments.
The defined penetration depth standardizes probe positioning relative to the target surface, which is critical for maintaining consistent gap voltage in eddy-current measurement systems.
NPT threaded interface allows direct installation into machine housings without custom adapters, simplifying field deployment and maintenance procedures.
Field Application Notes
Where is this housing used?
It is used in turbines, compressors, and industrial rotating equipment requiring stable proximity probe installation.
Why is penetration depth important?
It ensures correct probe-to-target distance 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 probes.
What is the benefit of NPT mounting?
It provides standardized mechanical integration into industrial equipment housings.
Installation & Commissioning Notes
Ensure correct torque application during NPT thread installation to avoid misalignment or mechanical stress on the housing body.
Verify probe penetration depth before commissioning to maintain correct gap calibration in the measurement system.
Maintain clean internal housing surfaces to avoid debris interference with probe alignment and signal accuracy.
Route probe cable away from high-voltage and VFD wiring to minimize electromagnetic interference.
Engineering & Operational Guidance
Avoid mechanical shock during installation, as it may affect probe alignment and penetration accuracy.
Use proper sealing practices on NPT threads to prevent oil or gas ingress in turbine environments.
Inspect housing periodically in high-vibration machinery to ensure mechanical stability over long operating cycles.
Ensure consistent grounding practices to reduce electrical noise in proximity measurement signals.
