330141-08-50-12-00 Bently Nevada 3300 XL 8 mm Probe, 5 m

Bently Nevada 330141-08-50-12-00: 3300 XL 8 mm Probe Overview

The Bently Nevada 330141-08-50-12-00 is a 3300 XL 8 mm probe with armor, engineered for precise eddy-current displacement measurement in rotating machinery. Its 5.0 m (16.4 ft) total length suits installations where the Proximitor sensor sits at a distance from the measurement point. The probe uses a miniature coaxial ClickLoc connector and FluidLoc cable, which prevents oil and other liquids from leaking through the cable interior. The 8 mm probe body provides thicker encapsulation of the probe coil in the molded PPS plastic tip, yielding a more rugged sensor. Bently Nevada recommends 8 mm probes for optimal robustness against physical abuse.

Performance and Reliability

The 330141-08-50-12-00 delivers an Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil) ±5% for standard 5-meter systems, measured over the 80 mil linear range from 0°C to +45°C. Deviation from best fit straight line (DSL) is less than ±0.025 mm (±1 mil) under the same conditions. The patented TipLoc molding method creates a robust bond between probe tip and body, while the CableLoc design provides 330 N (75 lbf) pull strength. The probe seals differential pressure between tip and case via a Viton O-ring. Relative humidity testing shows less than 3% change in Average Scale Factor at 93% humidity for up to 56 days. These engineering-grade specifications ensure precise, repeatable measurements in demanding industrial environments.

Installation and Compatibility

The 330141-08-50-12-00 is designed for use with a 5-meter Proximitor sensor only. The FluidLoc cable option prevents oil leakage through the cable interior, making it suitable for oil-lubricated machinery. The ClickLoc connector enables secure, tool-free connection. When integrating into existing 3300 XL systems, verify that the extension cable and Proximitor sensor match the 5-meter system length.
