Configured for high-frequency eddy-current displacement sensing in 3300 XL Transducer System platforms, the Bently Nevada 330104-00-05-20-02-CN (330104 Proximity Sensors) provides direct physical/electrical execution. It projects an alternating radio frequency magnetic field through its tip to measure continuous non-contact vibration and axial position of rotating shafts.

Eddy-Current Probe Scaling & Rotor Dynamics
The 330104-00-05-20-02-CN probe provides precise 7.87 V/mm (200 mV/mil) eddy-current probe scaling when connected into a complete 3300 XL transducer system matched for a 2.0-meter total system configuration. The 75 ohm coaxial transmission line maintains low phase shift and cross-talk suppression across dynamic frequency bands. Physical setting of the probe face yields accurate gap voltage validation targeting -10 VDC at nominal shaft center position, ensuring linear response across peak-to-peak vibration excursions in critical rotor dynamics monitoring.
Frequently Asked Questions
Q: How does the -CN suffix differ from standard agency approval options?
A: The -CN option indicates country-specific certification compliance for Chinese regulatory standards, requiring specialized field notification documentation and field installation reference guidelines.
Q: What function does the ClickLoc connector perform on option -02?
A: The ClickLoc miniature coaxial connector incorporates a tactile locking mechanism that prevents connector loosening under high machine vibration, maintaining coaxial contact resistance stability.
Q: Can this 2.0-meter probe cable option be connected directly to a 5.0-meter Proximitor sensor?
A: No, probe total length must match the Proximitor sensor calibration (or be combined with an extension cable to equal the total system design length, such as pairing a 2.0-meter probe with a 3.0-meter extension cable for a 5.0-meter Proximitor).
Field Installation Guidelines
- Clean the M10 x 1 threaded mounting port to clear debris and metal shavings prior to probe threading.
- Screw the 50 mm case probe into the mounting location by hand. Connect the output lead to a calibrated meter to perform gap setting.
- Position the probe tip relative to the target shaft until reaching the -10 VDC target gap voltage baseline at physical center.
- Secure the probe mounting body with a locknut, tightening to the standard thread torque spec without applying rotational stress to the cable boot exit.
- Push the ClickLoc coaxial connector securely onto the matching extension cable connector until fully locked. Slide a protective rubber connector sleeve over the mated junction to prevent earth ground loop paths.
