Bently Nevada 330105-02-12-05-02-00 3300 XL 8mm Proximity Probe

The Bently Nevada 330105-02-12-05-02-00 is a 3300 XL 8mm proximity probe with an M10x1 metric thread and a 0.5-meter cable. It delivers precise non-contact vibration and position sensing for industrial machinery, featuring a rugged PPS tip and a +177°C temperature rating.

Technical Purpose and System Role

The Bently Nevada 330105-02-12-05-02-00 operates as a high-precision eddy current sensor within the 3300 XL 8mm Proximity Transducer System. This probe measures the microscopic distance between the sensor tip and a rotating shaft to track radial vibration and axial displacement. By providing continuous, non-contact data to the 3500 Monitoring System, this probe enables early detection of mechanical faults such as unbalance or bearing wear. Consequently, industrial facilities rely on this sensor to prevent catastrophic machinery failure and implement condition-based maintenance strategies.

Operational Benefits and Industrial Applications

Maintenance teams deploy the 330105-02-12-05-02-00 primarily on fluid-film bearing machines where precision is paramount. The probe tip features a polyphenylene sulfide (PPS) construction, which successfully resists chemical corrosion and moisture ingress in demanding environments. Furthermore, the 3300 XL system provides superior temperature stability and interchangeability compared to previous sensor generations. Because of its rugged metric design, this probe is a standard choice for:

Steam turbine radial vibration monitoring
Centrifugal compressor thrust position tracking
Gas turbine shaft alignment and eccentricity
High-speed pump bearing health assessment

Installation and System Integration

Technicians must pair this probe with a matching 3300 XL extension cable and Proximitor Sensor to ensure measurement accuracy. For this 0.5-meter lead probe, the user typically selects a 4.5-meter extension cable to achieve a 5.0-meter total system length. Additionally, the 02 connector option includes a factory-installed connector protector. This component seals the coaxial connection against lubricating oils and environmental contaminants, which effectively eliminates signal noise and grounding issues. This integrated protection ensures that the monitoring system receives a clean, stable signal for critical asset protection.
