The Bently Nevada 330102-00-20-10-01-05 is a high-performance 3300 XL 8 mm proximity probe designed for use within the 3300 XL transducer system. This probe provides precise measurement of shaft vibration and position, essential for the monitoring and protection of critical rotating machinery.

Features

• System Compatibility: Fully compatible with 3300 XL Proximitor sensors and extension cables, supporting complete component interchangeability.
• Robust Design: Features a 3/8-24 UNF thread with integrated armor for enhanced protection in industrial environments.
• ClickLoc Connector: Equipped with a miniature coaxial ClickLoc connector, ensuring a secure, reliable connection that resists loosening due to vibration.
• Agency Approvals: Certified for use in hazardous areas including CSA, ATEX, and IECEx.

Applications

• Steam and Gas Turbines: Monitoring radial vibration and axial thrust to prevent blade-casing contact.
• Compressors: Shaft vibration and tachometer speed monitoring for centrifugal and axial units.
• Industrial Pumps and Motors: Protection for high-speed assets in oil, gas, and water processing.
• Generators and Gearboxes: Tracking displacement and thermal expansion for alignment monitoring.

Technical Specifications

Installation Guidelines

• Handling: Proximity probes are precision instruments. Avoid impacts to the probe tip, as damage to the ceramic or coil can affect linearity and accuracy.
• Mounting: Ensure the probe is mounted in a rigid bracket to prevent mechanical resonance. Use the provided lock nuts to secure the probe position after gapping.
• Wiring: Use 3-conductor shielded triad cable (16 to 24 AWG) between the Proximitor sensor and the monitoring system. Maximum recommended cable length is 305 meters (1,000 feet).
• Environmental Sealing: In environments with high moisture or oil exposure, utilize the included connector protectors or sealing tape to maintain signal integrity at the connection points.
• Safety: Always power down the monitoring system before disconnecting or replacing transducer components.

FAQ

What is the primary function of the 330102-00-20-10-01-05?

This probe measures both static (position) and dynamic (vibration) values by providing an output voltage proportional to the distance between the probe tip and a conductive surface.

Is this probe interchangeable with older Bently Nevada systems?

Yes, 3300 XL 8 mm components are designed to be electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components.

What is the typical gap voltage for this probe?

When the probe is correctly gapped and the shaft is centered, the normal gap voltage range is typically between -9 V and -11 V DC.
