Rotating Machinery Vibration Monitoring Solution – Bently Nevada 24701-28-05-20-024-03-02 | 3300 XL Series
The Bently Nevada 24701-28-05-20-024-03-02 is a precision-engineered Proximity Probe Housing Assembly designed for continuous, real-time vibration and position monitoring of rotating machinery. As a core component of the industry-leading 3300 XL Series, this assembly enables engineers to detect shaft displacement, radial vibration, and axial position with exceptional accuracy — protecting critical assets from catastrophic failure.
Where This Product Is Used
This proximity probe housing assembly is specified across a wide range of heavy-industry and process-critical environments:
- Steam & Gas Turbines — Continuous shaft radial vibration monitoring per API 670 requirements; early detection of rotor imbalance, misalignment, and bearing wear.
- Centrifugal & Axial Compressors — Monitoring shaft position and vibration in high-speed compressor trains in LNG, petrochemical, and refinery applications.
- Pumps & Blowers — Installed on large process pumps and induced-draft fans where bearing health is critical to plant uptime.
- Gearboxes & Expanders — Radial shaft monitoring in power recovery expanders and high-ratio gearboxes.
- Hydro & Wind Turbines — Shaft displacement measurement in renewable energy generation equipment.
- Marine Propulsion Systems — Monitoring propeller shaft vibration and alignment in vessel drive trains.
Wherever rotating shafts demand protection, the 24701-28-05-20-024-03-02 housing assembly provides the mechanical interface that keeps the eddy-current probe precisely positioned and mechanically secured.

Application-Specific FAQ
Q: Is the 24701-28-05-20-024-03-02 compatible with the Bently Nevada 3500 monitoring system?
A: Yes. This housing assembly is designed for use with the 3300 XL transducer system, which interfaces directly with the 3500 series monitors via standard Proximitor® drivers.
Q: Can this probe housing be used in ATEX Zone 1 hazardous areas?
A: The 3300 XL series carries ATEX and IECEx certifications. Verify the specific zone rating on the product datasheet or contact us to confirm suitability for your installation.
Q: What is the measurement range of the 3300 XL 8 mm probe used with this housing?
A: The standard linear range is 0.25 mm to 2.25 mm (gap), with a scale factor of approximately 7.87 V/mm. Confirm with the matched Proximitor® driver datasheet.
Q: Do I need to recalibrate my monitoring system after replacing the housing assembly?
A: The housing assembly itself does not affect calibration. However, if the probe or extension cable is also replaced, a full system calibration per Bently Nevada procedures is recommended.
