Description

The Bently Nevada 330101-00-20-20-02-CN is an 8 mm proximity probe belonging to the 3300 XL transducer system. Designed for high-precision measurement of static and dynamic shaft position and vibration in rotating machinery, this probe is a critical component for condition monitoring in industrial environments. It is fully compatible with the 3300 XL Proximitor sensor and extension cables, ensuring complete system interchangeability without the need for individual component bench calibration.

Features

• 8 mm probe diameter with 3/8-24 UNF thread
• Standard cable configuration with miniature coaxial ClickLoc connector
• Fully compliant with API 670 standards for linear range, accuracy, and temperature stability
• Backward compatible with non-XL 3300 series 5 mm and 8 mm transducer systems
• Hazardous area compliance including CSA, ATEX, and IECEx certifications

Applications

• Steam and gas turbines for power generation
• Centrifugal and axial compressors in oil, gas, and chemical processing
• Large industrial motors and generators
• Critical process pumps requiring high-precision shaft monitoring

Technical Specifications

Installation Guidelines

• Ensure the probe is mounted securely using the 3/8-24 UNF thread.
• Maintain proper gap voltage, typically between -9 V and -11 V DC, when the probe is centered within its linear range.
• Avoid exposing the probe to temperatures below -34 degC (-30 degF) to prevent damage to the internal pressure seal.
• Handle with care to avoid damage to the probe tip or coaxial cable connector.
• Always power down the monitoring system before connecting or disconnecting transducer components.

FAQ

What is the primary function of the 330101-00-20-20-02-CN?

This probe measures static and dynamic, axial and radial position and vibration in high-speed rotating machinery such as turbines, pumps, and compressors.

Is this probe compatible with older 3300 series systems?

Yes, each 3300 XL 8 mm transducer system component is backward compatible and interchangeable with other non-XL 3300 series 5 mm and 8 mm transducer system components.

What does the CN suffix indicate?

The CN suffix denotes that the product meets specific hazardous area standards, including ATEX, IECEx, and relevant certifications for the Chinese market.
