Bently Nevada 330905-00-09-05-05-02-05 3300 XL NSv Proximity Probe

Description

The 330905-00-09-05-05-02-05 is a 3300 XL NSv Proximity Probe specifically configured for precision vibration and axial position measurement in small-bore machinery. This non-contact, eddy-current transducer is designed for applications with limited target geometry or tight clearance requirements, such as aeroderivative turbines and high-speed equipment where standard probes may be too large or intrusive. The 330905 model features an M10x1 thread and is provided without stainless steel armor, facilitating installation in restricted spaces.

This transducer is a component of the 3300 XL NSv Proximity Transducer System, which includes the 330980 Proximitor Sensor and 330930 extension cable. The system maintains an accurate Average Scale Factor (ASF) even when monitoring shaft diameters smaller than 20 mm (0.8 in) or restricted counterbore areas. This specific configuration utilizes a 0.5 meter total system length and is fully compatible with Bently Nevada hazardous area installations, ensuring reliable, high-frequency response in demanding industrial environments.

Features

• Compatible with 3300 XL NSv Proximity Transducer System for small-bore shaft vibration and axial position monitoring.
• Non-contact eddy-current sensing technology eliminates mechanical wear and minimizes target area requirements.
• M10x1 probe thread configuration without armor for compact installation.
• Designed for high-speed machinery, aeroderivative turbines, and tight clearance mounting scenarios.
• ClickLoc miniature coaxial connectors with connector protectors (depending on configuration) to ensure environmental sealing.
• Meets rigorous hazardous area approval standards for Division 2 and Zone 2 installations.

Applications

• Small-bore machinery and high-speed equipment protection.
• Aeroderivative gas turbines.
• Radial vibration and axial position measurements in limited-clearance target areas.
• Critical machinery monitoring where target geometry restricts use of standard 3300 XL 8 mm probes.

Installation Guidelines

Ensure the transducer system is installed with the specified Proximitor Sensor (330980) and extension cable (330930). Proper installation includes isolating the Proximitor Sensor from the housing ground using a mounting pad to prevent ground loops. Cable routing should be performed to minimize interference with high-voltage lines. Connector protectors should be installed on all connections to ensure environmental sealing and prevent moisture ingress in industrial field conditions.
