Bently Nevada 330105-02-12-05-02-05 is an 8mm Reverse Mount Probe from the 3300 XL series. It is designed to be used with the Proximity Transducer System, a highly effective solution for non-contact measurement of displacement, position, and vibration in industrial machinery, particularly fluid-film bearing machines. The 3300 XL series offers a wide range of applications, including Keyphasor reference and speed measurements. The 330105-02-12-05-02-05 probe is optimized for vibration and position measurements and delivers highly accurate data for condition monitoring and machine protection.

Functional Description:

The 3300 XL 8 mm Reverse Mount Probe operates within the Proximity Transducer System to provide an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface. This enables the system to measure both static (position) and dynamic (vibration) values. Its key features include:

• Static and Dynamic Measurement: The probe provides accurate data for both static position measurements (e.g., shaft alignment, rotor position) and dynamic measurements (e.g., vibration monitoring, unbalance detection).
• Eddy Current Technology: The probe uses eddy current principles to measure the proximity to conductive surfaces without physical contact. This non-contact measurement ensures minimal wear and tear on the system and reduces the likelihood of mechanical interference with the machinery.
• Primary Applications:
  • Vibration and Position Monitoring: Essential for monitoring the health of fluid-film bearing machines, often found in turbines, compressors, pumps, and motors.
  • Keyphasor Reference and Speed Measurements: Used to monitor rotational speed and track timing marks for phase analysis.
• API 670 Compliance: The 3300 XL 8 mm system fully complies with the API 670 Standard (4th Edition), ensuring the highest standards of mechanical configuration, linear range, accuracy, and temperature stability. This makes it suitable for high-performance industrial applications that require strict compliance with international standards.

Key Benefits:

1. Advanced Performance: The 3300 XL 8 mm system provides the most advanced performance available in the eddy current proximity transducer systems, offering high accuracy, stability, and versatility for industrial machinery monitoring.
2. Interchangeability: The components of the 3300 XL 8 mm system (probes, extension cables, and Proximitor sensors) are fully interchangeable with other non-XL 3300 series components, including the 5 mm probes. This feature eliminates the need for bench calibration or matching of individual components, offering backward compatibility and ease of maintenance.
3. Flexibility in Sizing: The 3300 5 mm probe is available for applications where the standard 8 mm probe would be too large to fit in the available mounting space, providing flexibility in system configuration.
4. Reliability: The system's robust design, especially in harsh industrial environments, makes it suitable for use in critical applications where failure could result in expensive downtime or equipment damage.
