Bently Nevada 330101-00-75-20-02-05 3300 XL 8 mm Proximity Probe

Description

330101-00-75-20-02-05 specifies this unarmored 3300 XL 8 mm proximity probe configured with a 0.0 in unthreaded length (Option 00), 7.5 in overall case length (Option 75), 2.0 m total length (Option 20), miniature ClickLoc coaxial connector (Option 02), and CSA, ATEX, and IECEx hazardous area approvals (Option 05).

This specific configuration features standard unarmored 3/8-24 UNF threads with a 7.5-inch case length, allowing deep penetration into bearing housings or machinery casings. Operating on eddy-current principles, it pairs with a 3300 XL Proximitor sensor and extension cable to measure shaft vibration, dynamic motion, or axial position on critical rotating machinery like steam turbines, gas turbines, compressors, and high-speed pumps. The absence of a connector protector on Option 02 provides a compact ClickLoc connection footprint, while the Option 05 approvals satisfy hazardous area regulations.

Features

• Option 00 specifies a 0.0-inch unthreaded length, providing full-length 3/8-24 UNF threading on the probe casing.
• Option 75 provides a 7.5-inch overall case length for deep-reach installation in machinery housings.
• Option 20 provides a 2.0-meter total probe length using FEP-insulated coaxial standard cable.
• Option 02 designates a miniature coaxial ClickLoc connector without an integrated connector protector.
• Option 05 provides CSA, ATEX, and IECEx hazardous area safety approvals for industrial environments.
• Polyphenylene sulfide probe tip is molded for mechanical durability in harsh operating spaces.
• AISI 303 or 304 stainless steel case material offers corrosion resistance.

Applications

• Steam and gas turbine shaft vibration monitoring.
• Compressor and pump rotor axial position and displacement measurement.
• Critical rotating machinery protection in power plants, oil and gas, and petrochemical facilities.
• Speed and Keyphasor reference measurements.

Installation Guidelines

• Mount with appropriate probe gap per system calibration (typically 1.27 mm or 50 mils for 3300 XL 8 mm system).
• Route coaxial cable with proper shielding and grounding practices to prevent electromagnetic interference.
• Ensure minimum permissible cable bend radius of 25.4 mm (1.0 in) is maintained during routing.
• Do not exceed maximum rated torque values when mounting probe case or tightening ClickLoc connectors.
• Connection of standard ClickLoc connectors should be finger-tight.
