Description
The Bently Nevada 330103-00-03-10-02-02 is a 3300 NSv (Non-Standard velocity/small value) proximity transducer assembly designed for machine condition monitoring in applications with limited physical space or specialized target materials, such as small-size turbomachinery, centrifugal compressors, and gearboxes. It measures static and dynamic distances between the probe tip and a conductive target, providing raw voltage signals for vibration and position analysis.

Integration and Field Notes
When installing the 330103-00-03-10-02-02 probe in field machinery, ensure that the target material matches standard AISI 4140 steel or verify the material calibration factor if utilizing non-standard metals (e.g., austenitic stainless steel). The NSv design is specifically engineered for targets smaller than standard 3300 XL probes require, preventing edge-effect errors on restricted surfaces.
Always pair this probe with a matching 3300 NSv Proximitor Sensor calibrated for the correct cable length (1.0 meter integral probe cable combined with the appropriate extension cable and sensor unit to total 5 or 9 meters system length). Verify system gap voltage settings during initial cold commissioning to ensure the operating point sits mid-linear range at approximately -10 V DC.
Frequently Asked Questions
What is the primary difference between a standard 3300 XL probe and the 3300 NSv probe?
The 3300 NSv probe features a smaller 5 mm tip and altered electromagnetic field geometry, allowing accurate linear measurements on smaller shaft diameters or restricted target areas where standard 8 mm probes suffer from edge-effect interference.
Can this probe be used with a standard 3300 XL Proximitor Sensor?
No, 3300 NSv probes require a dedicated 3300 NSv Proximitor Sensor unit. Mixing standard 3300 XL sensors with NSv probes results in severe calibration and linearity errors.
