Bently Nevada 330104‑00‑06‑90‑12‑05 – Product Overview, Specifications, Applications, Advantages, and FAQs
Brand and Series
• Brand: Bently Nevada
• Series: 3300 XL Proximity Probe Series
The 3300 XL series is a high‑precision family of proximity probes widely used for monitoring shaft displacement and vibration on critical rotating machinery. The series is engineered for industrial environments where reliability, accuracy, and long-term durability are essential.
Product Description
The Bently Nevada 330104‑00‑06‑90‑12‑05 is an eddy current proximity probe designed for precise, continuous monitoring of shaft radial displacement and vibration. The probe converts shaft motion into a high-fidelity analog signal, which can be analyzed by monitoring and machinery protection systems.
This model combines a long cable length of 90 m with a connector type specified by the 12‑05 suffix, making it suitable for installations where monitoring electronics are located at a distance from the rotating machinery. Its construction ensures resistance to industrial contaminants, vibration, and thermal cycling, making it ideal for harsh plant conditions.
The 3300 XL series is recognized for its reliability, low signal drift, and compatibility with a wide range of monitoring modules, providing engineers with actionable data for predictive maintenance and machinery protection.
Applications
• Continuous shaft vibration monitoring on steam, gas, and hydro turbines in power plants.
• Condition monitoring of centrifugal compressors in petrochemical and refinery environments.
• High-speed pumps in chemical or water treatment facilities requiring accurate displacement measurements.
• Large electric motors and generators where bearing clearance and rotor alignment must be closely monitored.
• Gearboxes and industrial drives for early detection of misalignment, imbalance, or rubbing conditions.
• Rotating equipment across industrial production lines where predictive maintenance reduces unplanned downtime.
Advantages
- High Accuracy: Detects very small shaft displacements with linear, repeatable output.
- Rugged Construction: Designed for industrial environments with vibration, temperature variations, and fluid exposure.
- Extended Cable Length: The 90 m cable enables flexible installation across large plants without signal loss.
- System Compatibility: Integrates with 3300 XL monitoring electronics for predictive maintenance and protection.
- Low Maintenance: Minimal drift over time and long operational life reduce calibration and service needs.
- Versatility: Suitable for turbines, compressors, pumps, motors, and gearboxes in various industrial sectors.
