The 330851-02-000-034-50-00-00 is a compact eddy current proximity probe designed for high-precision, non-contact measurement of shaft vibration, axial displacement, and rotor dynamics in rotating machinery systems.
This model belongs to the NSv short-range configuration within the 3300 XL proximity transducer family. The “034” configuration indicates a specific calibrated sensitivity range variant used in slightly extended short-gap measurement conditions compared to lower-range NSv variants.
It is widely used in industrial monitoring systems where stable signal output, compact installation, and reliable long-term performance are required.
The system operates using an eddy current principle, where a high-frequency electromagnetic field is generated at the probe tip, and variations in distance to a conductive target surface are converted into proportional voltage signals.
This series is designed for compact machinery environments requiring high accuracy, stable output, and resistance to harsh industrial conditions.
The 330851-02-000-034-50-00-00 is widely applied in:
