Bently Nevada 330704-000-060-10-02-00 3300 XL 11 mm Proximity Probe

Description

330704-000-060-10-02-00 is an eddy-current non-contacting displacement probe used inside 3300 XL 11 mm proximity transducer systems. This specific configuration features an M14 x 1.5 metric thread with integrated stainless steel armor, a 0 mm unthreaded length (Option 000), and a 60 mm overall case length (Option 060). The probe has a total length of 1.0 meter (3.3 feet), terminated with a standard miniature coaxial ClickLoc male connector without agency approvals (Option 00).

Operating as a sensor within the 3300 XL 11 mm transducer line, this probe provides a nominal output of 3.94 V/mm (100 mV/mil) when paired with a matching Proximitor sensor and extension cable. The integrated flexible AISI 302 stainless steel armor protects the 75 ohm triaxial cable from physical wear, abrasion, and harsh machine environment conditions. This metric armor variant is used in installations requiring physical shielding and direct mechanical mounting on rotating machinery such as turbines, compressors, and pumps.

Features

• M14 x 1.5 threaded case made of corrosion-resistant AISI 304 stainless steel.
• Integrated flexible AISI 302 stainless steel armor with protective FEP outer jacket.
• Option 000 specifies a fully threaded case length with 0 mm of unthreaded probe body.
• Option 060 provides a 60 mm overall case length for specific insertion requirements.
• Option 10 total probe length of 1.0 meter (3.3 feet) for direct cable coupling.
• Option 02 ClickLoc miniature coaxial male connector for a locking, vibration-resistant connection.
• Polyphenylene sulfide (PPS) probe tip material for high environmental and chemical resistance.

Applications

This proximity probe is used for monitoring critical rotating machinery parameters, including:

• Radial shaft vibration and axial (thrust) position on fluid film bearing machines.
• Ramp differential expansion measurements on steam turbines.
• Rod position or rod drop measurements on reciprocating compressors.
• Tachometer, speed, and zero speed measurements.
• Phase reference (Keyphasor) signal generation.

Installation Guidelines

Observe the following installation criteria to avoid hardware damage and achieve proper signal response:

• Thread Engagement: The maximum allowable thread engagement length for M14 x 1.5 probe cases is 21 mm. Exceeding this length may cause mechanical binding during installation.
• Installation Torque: The recommended installation torque for M14 x 1.5 probe cases is 21.1 N-m (187 in-lb). Do not exceed the maximum rated limit of 63.3 N-m (560 in-lb).
• Connector Tightening: Ensure connections are clean and dry. Finger-tighten the miniature coaxial ClickLoc connectors, or use a connector torque wrench limited to 0.565 N-m (5 in-lb).
• Cable Protection: Maintain a minimum cable bend radius of 25.4 mm (1.0 in) for the armored probe cable during routing to avoid internal conductor fatigue.
