330141-08-50-11-00 Bently Nevada 3300 XL 8 mm Probe, 5 m

Product Overview

The Bently Nevada 330141-08-50-11-00 is a 3300 XL 8 mm probe with armor, engineered for precise shaft displacement and vibration measurement in rotating machinery. As part of the 3300 XL series, it delivers engineering-grade precision through a patented TipLoc molding method and CableLoc design. This 5-meter probe is designed for use with the 5-meter Proximitor sensor only, ensuring exact system compatibility. The 8 mm probe tip provides thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged sensor. The larger probe body diameter offers a stronger, more robust case, making it ideal for applications where physical abuse is a concern. With a FluidLoc cable option, this probe prevents oil and other liquids from leaking through the cable interior, enhancing reliability in oil-rich environments.

Applications and Use Cases

This probe is commonly used in turbine, compressor, and motor monitoring systems where accurate vibration data is critical. Because of its rugged 8 mm design, it suits installations with high mechanical stress. The FluidLoc cable option makes it particularly effective in oil-lubricated machinery, preventing liquid ingress. Moreover, the 5-meter length provides flexibility for reaching Proximitor sensors in remote locations. When selecting a probe, consider the operating temperature range and pressure sealing requirements. The 330141-08-50-11-00 is not pressure tested prior to shipment, so users must verify suitability for their pressure conditions.

Installation and Compatibility

Install the probe according to Bently Nevada guidelines, ensuring the ClickLoc connector is properly mated. Use only with the 5-meter Proximitor sensor to maintain system accuracy. The probe's armor protects the cable from mechanical damage, but avoid excessive bending. For integration with existing 3300 XL systems, verify that the Proximitor sensor matches the probe length. If wiring into a plant network, an external gateway may be required; consult AutoDCSTech for precise matching.

Maintenance and Reliability

Periodically inspect the probe tip and cable for wear or damage. The Viton O-ring seals differential pressure, but exposure to temperatures below -34°C (-30°F) may cause premature seal failure. Therefore, ensure operating conditions stay within the specified range. The robust construction minimizes downtime, but regular checks help maintain engineering-grade precision.
