The Bently Nevada 330904-04-14-05-02-00, also cataloged as the 330904 Proximity Sensors, operates as a dedicated hardware component for non-contact shaft vibration and positional displacement monitoring within 3300 XL NSv Machinery Monitoring System platforms. The transducer assembly features a 40 mm unthreaded length, a 140 mm overall case length, and a 0.5 m (20 in) standard coaxial cable terminated with a miniature coaxial ClickLoc connector.

Designed specifically for installations with narrow side-view clearances or counterbored mounting holes, the 330904-04-14-05-02-00 probe executes precision rotor dynamics monitoring on small-diameter shafts. When paired with a matching 3300 XL NSv Proximitor Sensor, eddy-current probe scaling produces a linear output voltage directly proportional to target surface gap distance. Achieving proper gap voltage validation (targeted at -10 VDC during installation) ensures proper linear positioning, optimal dynamic measurement range, and effective cross-talk suppression between closely spaced probe channels.
Q: What gap voltage should be targeted when setting up the 330904-04-14-05-02-00 probe mechanically?
A: Adjust physical probe insertion depth until the output voltage from the connected Proximitor Sensor reads -10 VDC, which corresponds to the midpoint of the calibrated linear range.
Q: Can the 0.5 m probe cable be wired directly to the TSI rack monitoring terminal?
A: No. The 0.5 m (20 in) integrated probe cable requires a matching 3300 XL NSv extension cable to establish the complete 5 m or 7 m total system length required by the Proximitor Sensor.
Q: How does the NSv probe tip profile differ from standard 8 mm proximity probes?
A: The NSv tip profile is engineered with a smaller magnetic footprint, allowing accurate vibration readings in narrow counterbores and tight spatial locations where standard 8 mm probes suffer from side-wall interference.
