The Bently Nevada 330104-00-20-15-12-05, also cataloged as the 330104 Proximity Sensors, operates as a dedicated hardware component for high-frequency non-contact shaft vibration and displacement detection within 3300 XL Transducer System platforms. It emits an alternating radio frequency magnetic field through its tip coil to detect relative physical distances against rotating shaft surfaces.

Eddy-Current Probe Scaling & Rotor Dynamics
The 330104-00-20-15-12-05 probe functions in conjunction with a matching extension cable and 3300 XL Proximitor sensor to maintain consistent eddy-current probe scaling at a linear sensitivity of 7.87 V/mm (200 mV/mil). During mechanical configuration, executing precise gap voltage validation targeting -10 VDC at the static shaft centerline positions the transducer in the middle of its linear operational range. This calibration prevents signal clipping during dynamic peak-to-peak excursions while preserving cross-talk suppression across adjacent channels monitoring complex rotor dynamics.
Frequently Asked Questions
Q: What engineering advantage does the FluidLoc cable configuration (-12 option) provide?
A: The FluidLoc cable structure incorporates internal sealing that prevents oil and process fluids from wicking through the inside of the cable assembly into clean junction boxes.
Q: How is physical alignment verified when setting up this probe model?
A: Mechanical alignment is verified by monitoring the DC gap voltage at the Proximitor sensor output until reaching the baseline -10 VDC target at nominal shaft rest position.
Q: Can a 1.5-meter probe lead (-15 option) connect directly to a standard 5.0-meter Proximitor sensor?
A: No, a 1.5-meter probe requires a matching 3.5-meter extension cable to achieve the required total 5.0-meter system length calibrated for the Proximitor sensor.
Field Installation Guidelines
- Inspect the M10 x 1 threaded mounting bore to ensure threads are clean and free of burrs or foreign particles.
- Thread the 200 mm stainless steel case into the mounting port by hand until the tip nears the target shaft surface.
- Apply power to the 3300 XL Proximitor sensor, monitor the DC gap output voltage, and adjust insertion depth to achieve the target -10 VDC setting.
- Tighten the locknut against the mounting bracket face to secure the physical position without imparting torsional stress on the cable exit boot.
- Secure the miniature coaxial ClickLoc connector to the extension cable and position a protective insulating boot over the junction to prevent ground potential loops.
