330141-08-50-02-00 Bently Nevada 3300 XL 8 mm Probe

What Is the 330141-08-50-02-00?

The 330141-08-50-02-00 is a Bently Nevada 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, this probe delivers engineering-grade precision for critical turbomachinery applications. The 8 mm probe diameter provides a thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged tip. Consequently, the larger probe body offers a stronger, more robust case against physical abuse. This specific model features a 5.0-meter total length, a miniature coaxial ClickLoc connector, and standard cable.

Key Specifications of the 330141-08-50-02-00

• Probe Type: 3300 XL 8 mm probe with armor
• Total Length: 5.0 meters (16.4 feet)
• Connector: Miniature coaxial ClickLoc, standard cable
• Nominal Probe DC Resistance: 8.73 ± 0.50 Ω
• Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ± 5%
• Probe Tip Material: Polyphenylene sulfide (PPS)
• Probe Case Material: AISI 303 or 304 stainless steel

Each specification is verified against the manufacturer's data. The 5-meter probes are designed for use with the 5-meter Proximitor sensor only.

Comparison with Similar Probe Configurations

• 330141-08-50-02-00 (this model): 5.0 m length, ClickLoc connector, standard cable, no agency approval.
• Other 3300 XL 8 mm probes: May offer different total lengths (e.g., 1 m or 9 m), alternative connector types, or FluidLoc cable options. However, these options are not interchangeable without verifying system compatibility.
• 3300 XL 5 mm probes: Smaller diameter, less robust encapsulation, typically used where space is limited but physical abuse risk is lower.

When selecting a replacement or upgrade, always match the probe length to the Proximitor sensor and extension cable for accurate scale factor.

Applications and Use Cases

This probe is ideal for continuous monitoring of radial vibration, axial position, and eccentricity on steam turbines, compressors, and large motors. Because of its armored cable, it suits installations where mechanical protection is necessary. Additionally, the 8 mm probe diameter provides optimal robustness against physical abuse, making it a reliable choice for harsh industrial environments. The 330141-08-50-02-00 integrates seamlessly with 3300 XL series Proximitor sensors and extension cables.

Installation and Maintenance Guidance

Install the probe according to Bently Nevada's documented procedures, ensuring the probe tip is positioned within the linear range. Use the specified ClickLoc connector to mate with the extension cable. Periodically inspect the probe tip and cable armor for wear or damage. Avoid exposing the probe to temperatures below -34°C (-30°F), as this may cause premature pressure seal failure. For detailed maintenance intervals, refer to the official datasheet.
