The Bently Nevada 330105-02-12-05-02-05 is a high-precision 3300 XL 8 mm reverse mount proximity probe designed for use within industrial proximity transducer systems. This sensor provides accurate, non-contact measurements of static position and dynamic vibration, serving as a critical component for machine protection and condition monitoring in rotating equipment.

Features

• Designed for 3/8-24 UNF thread mounting configurations.
• Features a Miniature ClickLoc coaxial connector for secure, reliable signal transmission.
• Fully compatible with Bently Nevada 3300 XL series Proximitor sensors and extension cables.
• Supports complete interchangeability of components, eliminating the need for individual bench calibration.
• Compliant with API 670 standards for mechanical configuration, linear range, and temperature stability.

Applications

• Power Generation: Monitoring shaft vibration and displacement in steam and gas turbines, as well as large feedwater pumps.
• Oil & Gas: Providing mechanical protection for centrifugal and axial flow compressors and expanders.
• Manufacturing: Monitoring bearing conditions in heavy-duty fans, blowers, and industrial gearboxes.
• Petrochemical: Non-contact position measurement for high-speed rotating pump sets to prevent mechanical interference.

Technical Specifications

Installation Guidelines

• Ensure the probe is mounted in a stable, vibration-resistant location using the specified 3/8-24 UNF threads.
• Handle the probe tip with care; avoid physical impact or contamination to maintain measurement accuracy.
• Use only compatible Bently Nevada 3300 XL extension cables and Proximitor sensors to ensure system integrity.
• Verify that all coaxial connections are properly seated and tightened to prevent signal noise or intermittent data.
• Always power down the associated monitoring system before connecting or disconnecting the probe to prevent electrical damage.
• Maintain proper cable routing away from high-voltage power lines to minimize electromagnetic interference (EMI).

FAQs

What is the primary function of this probe?

This probe measures non-contact displacement and vibration in rotating machinery, providing real-time data for condition monitoring and machine protection systems.

Is this model compatible with older Bently Nevada systems?

Yes, the 3300 XL series is designed for backward compatibility with non-XL 3300 series 5 mm and 8 mm transducer elements.

What does the 05 agency approval code signify?

The 05 code indicates that the unit carries CSA, ATEX, and IECEx certifications, making it suitable for use in hazardous environments where these standards are required.
