Bently Nevada 330104-05-10-50-02-00 3300 XL 8 mm Proximity Probe

Description

Option 05 (50 mm unthreaded length), Option 10 (100 mm overall case length), Option 50 (5.0 m total length with stainless steel armor), and Option 02 (ClickLoc connector without protector) specify this metric 3300 XL 8 mm proximity probe configuration — 330104-05-10-50-02-00. This eddy-current non-contact transducer is part of the 3300 XL 8 mm Proximity Transducer System, specifically featuring M10 x 1 metric threads and integrated flexible stainless steel armor with an outer FEP jacket to safeguard the coaxial cable against mechanical wear, cutting, and abrasion in harsh rotating machinery environments.

Unlike unarmored versions or shorter cables, the armored 5.0-meter integral cable on this configuration eliminates the requirement for an intermediate connector junction within the machinery casing, improving reliability in the presence of lubricating oil and moisture. This probe is designed for use exclusively with the 5-meter Proximitor sensor, ensuring full compliance with the API 670 standard for mechanical configuration, linear range, and temperature stability without needing manual calibration.

Features

• Option 05 specifies a 50 mm unthreaded section, ideal for recessed mount designs.
• Option 10 specifies a 100 mm overall M10 x 1 threaded case length for structural depth penetration.
• Option 50 provides a 5.0-meter integral coaxial cable, designed for direct connection to a 5-meter Proximitor sensor without extension cables.
• Option 02 includes a miniature ClickLoc coaxial connector for secure, reliable electrical connection.
• Option 00 designates standard configuration without hazardous area agency approvals.
• Flexible stainless steel armor with a protective FEP outer jacket shields the integral cable from mechanical cutting, abrasion, and fluid entry.
• Backward compatible and interchangeable with non-XL 3300 series 5 mm and 8 mm components.

Applications

• Radial vibration measurements on high-speed rotating shafts supported by fluid-film bearings.
• Axial position and thrust shaft displacement monitoring.
• Keyphasor reference and rotational speed measurements.
• Continuous machinery protection in turbines, compressors, gearboxes, pumps, and motors.

Installation Guidelines

• Verify that the unthreaded length (50 mm) is at least 20 mm less than the case length (100 mm) to avoid interference with the mounting structure.
• Maintain proper clearance of at least 15 mm around the probe tip to prevent cross-talk or target influence from surrounding metal surfaces.
• Recommended gap setting for radial vibration is -9 Vdc (approximately 1.27 mm or 50 mils) corresponding to the midpoint of the linear range.
• Do not exceed the maximum thread engagement length of 15 mm during installation to prevent binding or thread damage.
• Route the armored integral cable carefully, maintaining a minimum bend radius of 25.4 mm (1.0 in) to prevent damage to the FEP jacket and inner conductors.
• Hand-tighten the ClickLoc coaxial connector to finger tight; do not use pliers unless pairing with older non-XL connectors where a 1/8 turn is recommended.
