Bently Nevada 330103-03-06-05-02-00 3300 XL 8 mm Proximity Probe

Description

330103-03-06-05-02-00 is a metric-threaded 3300 XL 8 mm proximity probe configuration engineered without external coaxial armor. This specific model features an M10 x 1 case thread, a 30 mm unthreaded length (Option 03), a 60 mm overall case length (Option 06), and a 0.5-meter (1.6-foot) total length (Option 05). Designed with a standard cable and a miniature coaxial ClickLoc connector (Option 02), this unit is configured without hazardous area approvals (Option 00), making it ideal for standard, non-certified industrial environments.

This probe serves as an eddy-current displacement sensor within the Bently Nevada 3300 XL machinery protection system. It measures static and dynamic distance between the probe tip and a conductive target, such as a fluid-film bearing shaft. By operating in conjunction with a 3300 XL Proximitor sensor and a corresponding extension cable, this 0.5-meter probe is calibrated to measure shaft vibration, axial position, and Keyphasor speed references.

Unlike variants configured with stainless steel armor (such as the 330104 series) or those with integrated connector protectors (Option 01), this unarmored configuration utilizes a standard FEP insulated cable and a bare ClickLoc connector for direct routing in protected conduits. Additionally, its short 0.5-meter total length is ideal for space-constrained installations where the connection to the extension cable occurs near the machine housing.

Features

• Metric case thread: M10 x 1 thread size with a hex size of M10.
• Case dimensions: 60 mm overall case length with a 30 mm unthreaded section, complying with the minimum 20 mm differential rule.
• 0.5-meter total length: Compact cable run optimized for close-coupled connection to standard extension cables.
• ClickLoc coaxial connector: Gold-plated miniature male coaxial connector without a connector protector (Option 02).
• Unarmored cable: Standard 75 Ohm triaxial FEP insulated probe cable for standard routing.
• Target compatibility: Calibrated for AISI 4140 steel targets.
• Temperature rating: Standard operating temperature range of -52 degC to +177 degC.

Applications

• Rotating machinery monitoring in fluid-film bearing environments.
• Radial shaft vibration measurement in industrial motors, pumps, and fans.
• Axial shaft position tracking on industrial turbines and centrifugal compressors.
• Speed and Keyphasor reference measurements on high-speed rotating elements.
• Retrofitting existing non-XL metric installations using M10 x 1 threads.

Installation Guidelines

• Cable Routing: Ensure minimum cable bend radius of 25.4 mm is observed to prevent signal attenuation or mechanical damage to the coaxial layers.
• Torque Limits: Thread engagement into the machine housing must not exceed 15 mm. Tighten probe case to a maximum recommended torque of 22.6 N-m (200 in-lbf).
• Connector Maintenance: Ensure coaxial ClickLoc connectors are kept clean, dry, and free of turbine oil or moisture. Align and press together until the mechanical "click" is felt. Do not over-torque past 0.565 N-m (5 in-lbf) if connection tools are used.
• Grounding: Ensure the sensor shielding is properly terminated to prevent electrostatic or electromagnetic interference in the final signal path.

Compliance and Certifications

This specific configuration (Option 00) does not require hazardous area certifications and is designed for use in standard, general-purpose industrial environments. General compliance includes CE Mark and RoHS guidelines where applicable.
