Bently Nevada 330101-32-57-05-01-05 3300 XL 8 mm Proximity Probe

The Bently Nevada 330101-32-57-05-01-05 is a high-performance 3300 XL 8 mm proximity probe designed for precise measurement of static and dynamic shaft position and vibration in rotating machinery. As part of the industry-standard 3300 XL series, this transducer system utilizes eddy-current technology to provide reliable, non-contact monitoring for critical industrial assets.

Features

• Designed for integration with 3300 XL Proximity Transducer Systems.
• Features a 3/8-24 UNF thread for secure mounting.
• Equipped with a miniature coaxial ClickLoc connector and connector protector.
• Standard cable configuration for reliable signal transmission.
• Fully compliant with API 670 standards for mechanical configuration, linear range, and accuracy.
• Backward compatible with non-XL 3300 series 5 mm and 8 mm components.

Applications

• Steam & Gas Turbines: Monitors radial vibration and axial thrust to prevent blade-to-casing contact.
• Centrifugal & Axial Compressors: Provides essential shaft vibration and tachometer speed monitoring.
• Large Industrial Pumps & Motors: Protects high-speed assets in demanding oil, gas, and water processing environments.
• Generators & Gearboxes: Tracks displacement and thermal expansion to ensure proper machine alignment.

Technical Specifications

Installation Guidelines

• Mounting: Ensure the probe is mounted in a rigid, vibration-resistant bracket to maintain a consistent gap between the probe tip and the target surface.
• Gap Setting: Standard installation typically requires a gap setting of 1.27 mm (50 mils), corresponding to the -10 Vdc center position.
• Target Material: Ensure the target shaft material is compatible with the probe calibration (typically AISI 4140 steel).
• Handling: Proximity probes are precision instruments; handle the probe tip with care to avoid mechanical damage or scratches.
• Environment: While the probe is robust, ensure the coaxial cable is routed away from high-EMI sources and protected from excessive heat or mechanical abrasion.

FAQ

What is the primary function of the 330101-32-57-05-01-05?

This probe is an eddy-current transducer used to measure dynamic and static vibration, such as radial vibration, shaft position, and axial thrust on industrial rotating machinery.

How does the measurement work?

The probe is energized by a high-frequency AC signal, creating an electromagnetic field. It measures the distance (gap) between the probe tip and a conductive target surface, converting this distance into a voltage signal.

Is this probe compatible with older systems?

Yes, 3300 XL 8 mm components are electrically and physically interchangeable with non-XL 3300 series 5 mm and 8 mm transducer components, allowing for seamless integration in legacy systems.
