The Bently Nevada 330103-00-04-10-01-00, also cataloged as the 330103 Proximity Sensors, operates as a dedicated hardware component for non-contact shaft vibration and displacement measurement within 3300 XL Transducer System platforms. It projects an alternating radio frequency field through its polyphenylene sulfide tip to track relative target distance against rotating machinery shafts.

The 330103-00-04-10-01-00 probe works in conjunction with a matching extension cable and Proximitor sensor to provide standardized eddy-current probe scaling at a linear sensitivity of 7.87 V/mm (200 mV/mil). During dynamic system setup, gap voltage validation targeting -10 VDC at the physical shaft centerline ensures maximum dynamic range for peak-to-peak vibration excursions. Correct physical alignment prevents saturation under high shaft displacement and maintains cross-talk suppression between orthogonal probe pairs installed for rotor dynamics tracking.
Q: What function does the factory-installed connector protector serve on option -01?
A: The connector protector seals the ClickLoc miniature coaxial interface against environmental contaminants such as oil and moisture while insulating the coaxial shield from unintentional grounding against the machine housing.
Q: Can this 1.0-meter probe cable connect directly to a 5.0-meter Proximitor sensor?
A: No, a 1.0-meter probe requires a matching 4.0-meter extension cable to complete the total 5.0-meter system length required for accurate electrical calibration of the Proximitor sensor.
Q: What is the mechanical thread specification for the 330103 base model?
A: The 330103 series probe casing features a standard 3/8-24 UNF external thread along its stainless steel body.
