The Bently Nevada 330103-00-05-05-02-CN is a high-precision 3300 XL 8 mm proximity probe engineered for non-contact vibration and position measurement in critical rotating machinery. As part of the 3300 XL transducer system, this probe provides reliable data for monitoring radial vibration, axial thrust, and shaft speed in industrial environments.

Features

• 8 mm probe tip diameter for high-resolution eddy current sensing.
• M10 x 1 thread configuration for secure mounting in machine housings.
• Standard cable design with a 0.5-meter length and miniature coaxial ClickLoc connector.
• Designed for full electrical and physical interchangeability with legacy 3300 5 mm and 8 mm components.
• Non-armored cable construction.

Applications

• Turbines: Monitoring radial vibration and axial thrust in steam and gas turbines.
• Compressors: Preventing shaft-to-bearing contact in centrifugal and axial compressors.
• Pumps & Fans: Health monitoring for large-scale industrial pumps and cooling fans.
• Generators & Motors: Ensuring stable operation for large rotating electric machinery.
• Gearboxes: Detecting bearing wear and shaft misalignment through vibration analysis.

Installation Guidelines

• Mounting: Thread the probe into the machine housing or mounting bracket. Use caution to avoid over-tightening, which can damage the probe case or threads.
• Gap Setting: Use a digital micrometer or feeler gauge to establish the initial gap. The standard recommended gap is approximately 1.27 mm (50 mils), which corresponds to -9.0 Vdc at the Proximitor output.
• System Compatibility: This probe is designed for use with the 3300 XL Proximitor sensor. Ensure the extension cable and sensor match the system requirements.
• Handling: As a sensitive electronic component, handle the probe tip with care to avoid scratches or impacts that could affect measurement accuracy.
• Environment: Ensure the cable routing avoids high-EMI sources and adheres to the minimum permissible bend radius.
