The Bently Nevada 330905-06-14-10-02-00, also cataloged as the 330905 Proximity Sensors, operates as a dedicated hardware component for non-contact shaft displacement and dynamic vibration measurement within 3300 XL NSv machinery monitoring platforms. Built for installation in restricted counterbores and small shaft geometries, this probe incorporates an unarmored M10 x 1 threaded stainless steel case with a 60 mm unthreaded section, 140 mm overall case length, and a 1.0 m (39 in) FEP coaxial cable terminated with a ClickLoc connector.

The 330905-06-14-10-02-00 transducer uses calibrated eddy-current probe scaling to measure real-time rotor dynamics on tight shaft targets and narrow side-clearance installations. The RF signal generated by the matching 3300 XL NSv Proximitor Sensor produces a linear output voltage relative to the distance between the PPS probe tip and the conductive shaft surface. Performing gap voltage validation to achieve a target setting of -10 VDC positions the transducer at the midpoint of its calibrated linear range, providing cross-talk suppression and signal integrity across closely spaced monitoring channels.
Q: What target gap voltage reading indicates correct physical setup for the 330905 probe?
A: Mechanical thread insertion depth must be set until the output voltage measured at the connected 3300 XL NSv Proximitor Sensor reads -10 VDC, centering the probe in its linear operating span.
Q: Can the 1.0 m probe cable be routed directly to monitor terminal strips without an extension cable?
A: No. The integrated 1.0 m (39 in) FEP coaxial cable must couple via its miniature ClickLoc connector to a matching 3300 NSv extension cable to complete the 5.0 m or 7.0 m tuned system loop length.
Q: What function does the 60 mm unthreaded length (-06 option) serve during installation?
A: The 60 mm unthreaded neck allows the probe body to pass through unthreaded mounting sleeve clearances or thick housing walls without thread galling before engaging the interior M10 x 1 mounting threads.
