Bently Nevada 330103-05-10-02-00 3300 XL Proximity Probe

Description

Option 05 (50 mm overall case length) and Option 10 (1.0 meter total length) specify this metric 3300 XL 8 mm proximity probe configuration — 330103-05-10-02-00. This non-contact eddy-current sensor is designed for mounting configurations requiring metric threads without mechanical armor. The probe tip features a molded polyphenylene sulfide (PPS) plastic face that seals against high pressure, while the threaded body utilizes metric M10 x 1 threading for direct installation into machine casings.

This 330103 configuration is typically parsed as a 4-segment variant code where the leading unthreaded length code is omitted (representing 0 mm of unthreaded length). This translates to a fully threaded 50 mm case. It features a standard 1.0 meter integral coaxial cable terminated with a miniature ClickLoc gold-plated coaxial connector. It connects to a 3300 XL extension cable and Proximitor sensor to form a complete machinery protection monitoring chain, serving roles in dynamic shaft vibration, axial position, and speed sensing on rotating machinery.

Features

• Standard metric M10 x 1 threaded body without stainless steel armor.
• Fully threaded 50 mm case length with 0 mm unthreaded portion.
• Integral 1.0 meter (3.3 feet) coaxial cable for compact, close-coupled installations.
• Miniature gold-plated coaxial ClickLoc connector for secure signal coupling.
• Standard cable insulation rated for high-temperature turbine oil environments.
• No agency approvals requested, configured for standard non-hazardous industrial areas.

Applications

• Shaft dynamic vibration measurements on gas and steam turbines.
• Thrust position and axial displacement monitoring in industrial compressors.
• Bearing oil film clearance and casing expansion tracking.
• Rotational speed and phase reference measurements (Keyphasor applications).
• Fluid-film bearing performance monitoring in high-pressure pumps and utility fans.

Installation Guidelines

• Exceeding 15 mm of thread engagement during installation into matching metric threaded casings may bind or damage the probe threads.
• Ensure that probe-to-extension-cable connections are kept clean and dry. Use of connector protectors is recommended when exposed to liquid spray or moisture.
• Verify that the combined length of the proximity probe and the extension cable exactly matches the total calibrated length specified on the Proximitor sensor (e.g., 5-meter or 9-meter system calibration).
• Maintain a side-view clearance of at least 1.5 times the probe tip diameter from any surrounding structural metal to prevent target distortion.

Compliance and Certifications

• RoHS Compliant
• CE Marked
• Approved for use in standard non-hazardous industrial installations.
