Bently Nevada 330707-00-25-10-02-00 3300 XL 11 mm Proximity Probe

Description

330707-00-25-10-02-00: 3300 XL 11 mm proximity probe, 5/8-18 UNF thread without armor, Option 00 unthreaded length, Option 25 case length, Option 10 total length, Option 02 miniature coaxial ClickLoc connector with standard cable, and Option 00 agency approvals not required.

This proximity probe is used for non-contact vibration and displacement measurement in rotating machinery. It features a wider 4.0 mm (160 mils) linear range compared to standard 8 mm probes, which is suitable for thrust position, differential expansion, or reciprocating compressor rod position monitoring. The unarmored cable design allows direct connection to a compatible 3300 XL extension cable to achieve a total system length of 5.0 meters or 9.0 meters. Gold-plated ClickLoc connectors provide a secure, locked mating connection, preventing loosening in vibrating environments.

Features

• 5/8-18 UNF threaded case configuration without protective armor
• 0.0 in unthreaded length (Option 00) for fully threaded case versatility
• 2.5 in overall case length (Option 25) for standard machine housing penetrations
• 1.0 meter (3.3 feet) total cable length (Option 10)
• Miniature ClickLoc coaxial connector on a standard FEP triaxial cable (Option 02)
• Option 00 configuration for applications where hazardous area approvals are not required
• TipLoc molding process provides a secure bond between the polyphenylene sulfide (PPS) tip and the stainless steel case
• CableLoc design provides a 330 N (75 lb) pull strength from probe case to probe lead

Applications

• Axial (thrust) shaft position measurements on industrial steam turbines and turbomachinery
• Ramp differential expansion measurements on steam turbines
• Rod position or rod drop monitoring on reciprocating compressors
• Radial vibration and speed measurements on heavy rotating machinery
• Phase reference (Keyphasor) signal generation

Installation Guidelines

Ensure the 5/8-18 UNF-2A thread is handled carefully during installation to prevent damage. Apply a recommended mounting torque of 15.2 N-m (133 in-lb), and do not exceed the maximum rating of 45.2 N-m (400 in-lb). Maintain a minimum cable bend radius of 25.4 mm (1.0 in) along the entire run of the 1.0-meter standard triaxial cable.

To establish a clean, moisture-sealed connection with the extension cable, use connector protectors or wrap the connection in silicone self-fusing tape. Align the probe to a 2.5 mm (100 mils) nominal gap relative to the AISI 4140 steel target for standard linear range operation.
