The Bently Nevada 330905-00-03-10-02-00, also cataloged as the 330905 Proximity Sensors, operates as a dedicated hardware component for non-contact shaft vibration and displacement monitoring within 3300 XL 8mm Proximity Sensor System platforms. The probe assembly features a metric thread profile with a 0 mm unthreaded length option, a 30 mm overall case length option, and a 1.0 m (39 in) standard coaxial cable terminated with a miniature coaxial ClickLoc connector.

The 330905-00-03-10-02-00 proximity probe utilizes eddy-current sensing principles to deliver high-resolution displacement data for rotor dynamics evaluation. Connected in series with a matching 3300 XL Proximitor Sensor and extension cable, eddy-current probe scaling produces a linear output voltage proportional to target shaft clearance. Proper mechanical positioning during installation requires gap voltage validation targeted at -10 VDC near the center of the dynamic linear range, which mitigates cross-talk suppression issues when probes are arranged in orthogonal XY pairs.
Q: What gap voltage reading indicates correct mechanical installation of the 330905-00-03-10-02-00 probe?
A: Mechanical insertion depth should be adjusted until the output from the connected 3300 XL Proximitor Sensor reads -10 VDC, placing the transducer at the midpoint of its calibrated linear range.
Q: Can the 1.0 m probe cable connect directly to an online TSI monitoring system card?
A: No. The integrated 1.0 m (39 in) probe cable must be connected through a matching 3300 XL extension cable to fulfill the total 5.0 m or 7.0 m system electrical length required by the Proximitor Sensor.
Q: What connector type is supplied with the 02 option code on this probe?
A: Option 02 designates a miniature coaxial ClickLoc connector mounted on a standard coaxial cable without an external connector protector.
