Bently Nevada 330101-00-20-20-02-CN 3300 XL 8 mm Proximity Probe

Description

Engineered for high-reliability industrial machinery monitoring, the 330101-00-20-20-02-CN eddy current sensor is a core element of the Bently Nevada 3300 XL 8 mm Proximity Transducer System. This sensor provides continuous, non-contact measurement of static (gap) and dynamic (vibration) displacement in fluid-film bearing machines. The rugged design ensures stable electrical and mechanical performance in demanding industrial environments.

This specific model configuration features an unthreaded body design (0.0 inches unthreaded length) coupled with a 2.0-inch overall case length. The sensor comes integrated with a 2.0-meter (6.6-foot) standard coaxial cable terminated with a miniature ClickLoc connector, optimizing it for installation where intermediate cabling or specific enclosure paths are utilized. The "CN" designation signifies specific country-level agency compliance approvals.

Features

• ClickLoc Connector: Miniature coaxial ClickLoc connector ensures a secure, vibration-resistant connection to the extension cable.
• Interchangeability: Fully compatible and interchangeable with other Bently Nevada 3300 XL 8 mm series transducer components.
• Robust Environmental Resistance: Built to withstand aggressive lubricants, high humidity, and extreme temperature variations.
• Precision Measurement: Designed to offer a linear range of 2.0 mm (80 mils) when paired with a matching 3300 XL proximity proximitor sensor.

Applications

• Steam and gas turbine shaft vibration and position monitoring.
• Centrifugal and axial compressor diagnostics.
• High-speed industrial pump monitoring.
• Generator bearing air-gap and shaft displacement measurements.

Installation Guidelines

To ensure optimal sensor performance and prevent measurement errors, observe the following engineering recommendations:

• Verify that the target area on the rotating shaft is free of surface defects, mechanical runout, or magnetic hot spots.
• Ensure the minimum clearance around the probe tip is maintained to prevent side-viewing interference from adjacent metal components.
• Secure the coaxial cable in a dedicated protective conduit or tray to prevent physical wear, bending fatigue, or electrical noise interference.
• Verify calibration using a calibrated spindle micrometer prior to final commissioning.

Compliance and Certifications

• CN Approvals (Country-Specific Hazardous Area Certification options)
