Vibration Monitoring Solution – Bently Nevada BA21504-00-08-10-02 | 3300 XL Series Standard Mount Proximity Probe
Where This Product Is Used
The Bently Nevada BA21504-00-08-10-02 is a standard mount eddy-current proximity probe engineered for continuous, non-contact measurement of shaft vibration, axial position, and differential expansion in rotating machinery. It is widely deployed in:
- Steam & Gas Turbines – radial shaft vibration and thrust position monitoring on high-speed rotors
- Centrifugal Compressors – real-time orbit and gap measurement to detect rotor instability
- Pumps & Fans – bearing journal monitoring in petrochemical and power-generation facilities
- Gearboxes – gear mesh frequency analysis and shaft eccentricity detection
- Marine Propulsion Systems – shaft alignment verification and vibration surveillance
- Paper & Steel Mills – roll position and vibration monitoring in continuous-process machinery
Wherever API 670 compliance is mandated, the BA21504-00-08-10-02 is the field-proven choice for OEM and retrofit installations alike.

Application-Specific FAQ
Q: Is the BA21504-00-08-10-02 compatible with the older 3300 series monitors?
A: The 3300 XL system is backward-compatible with most 3300 series monitors when used with the correct Proximitor® driver. Confirm your monitor model before ordering.
Q: What target material is this probe calibrated for?
A: Factory calibration is performed on AISI 4140 steel. For non-standard target materials (e.g., titanium, Inconel), a field recalibration or material correction factor is required.
Q: Can this probe be used in a hazardous (Ex) area?
A: The standard BA21504-00-08-10-02 is not ATEX-certified. For Zone 1/Zone 2 installations, specify the appropriate Bently Nevada Ex-rated variant and consult your safety engineer.
Q: What is the recommended replacement interval?
A: Bently Nevada proximity probes have no mechanical wear parts. Replacement is typically triggered by calibration drift, physical damage, or as part of a scheduled major overhaul (T&I).
Q: Do you supply the full 3300 XL system (probe + cable + driver)?
A: Yes. Contact us with your complete BOM and we will provide a consolidated quotation for the matched system.
