Bently Nevada 330102-00-30-10-02-00 3300 XL 8 mm Proximity Probe

Description

Fully threaded 3/8-24 UNF steel probe body (Option 00) with 3.0 in case (Option 30) and 1.0 m lead (Option 10) — 330102-00-30-10-02-00. This configuration of the 3300 XL 8 mm proximity probe is equipped with integral stainless steel armor for mechanical protection in severe environments, distinguishing it from unarmored variants such as the 330101 series. It features a miniature coaxial ClickLoc connector without a connector protector (Option 02) and does not require hazardous area approvals (Option 00).

This eddy-current proximity probe belongs to the 3300 XL 8 mm Transducer System, operating with a nominal scale factor of 7.87 V/mm (200 mV/mil). It pairs with a 3300 XL Proximitor sensor and a 3300 XL standard extension cable to form a complete machinery monitoring loop. The system measures static (position) and dynamic (vibration) parameters, typical for fluid-film bearing machines such as steam turbines, gas turbines, compressors, and pumps.

Features

• Fully threaded steel body (Option 00) with 3.0 in overall case length (Option 30) for deep mounting.
• Flexible stainless steel armor sleeve to protect the coaxial lead from physical wear, abrasion, and oil exposure.
• Integrated 1.0 m total cable length (Option 10) matching standard 3300 XL transducer configurations.
• Miniature coaxial ClickLoc male connector (Option 02) for connection to standard extension cables.
• Polyphenylene sulfide (PPS) molded probe tip providing environmental sealing and insulation.
• Unapproved configuration (Option 00) for general-purpose applications where hazardous area certificates are not required.

Applications

• Radial shaft vibration measurement on fluid-film bearing machines.
• Axial rotor position monitoring.
• Keyphasor reference and speed sensing.
• Machinery protection on industrial steam turbines, turbo-compressors, pumps, and fans.

Installation Guidelines

Ensure correct mechanical gapping during installation. The nominal gap is 1.27 mm (50 mils), which corresponds to -10 Vdc output from the associated Proximitor sensor. Use locknuts to secure the probe body in place. Avoid exceeding 1.5 times the nominal thread diameter for thread engagement (maximum 0.563 inches for 3/8-24 threads). Run the armored cable with a minimum bend radius of 25.4 mm (1.0 inch). Ground the extension cable shield at the Proximitor end only to avoid ground loops.
