Bently Nevada 330903-00-03-10-02-05 3300 NSv Proximity Probe

The Bently Nevada 330903-00-03-10-02-05 3300 NSv Proximity Probe is a precision-engineered component of the 3300 NSv (Narrow Signal Velocity) series, designed for machinery condition monitoring and vibration measurement. It is primarily used in small and compact machines such as gearboxes, compressors, pumps, and turbines where standard proximity probes may not be suitable due to space constraints.

The probe delivers accurate, reliable measurements of shaft vibration and position by detecting relative motion between the probe tip and a conductive target. Its design ensures compatibility with tight spaces while maintaining high measurement sensitivity and stability in harsh industrial environments.

FAQ

Q1: What is the operating principle of the 330903-00-03-10-02-05 probe?

A1: It uses eddy-current technology to measure the distance between the probe tip and a conductive target, enabling detection of shaft vibration and displacement.

Q2: Can this probe be used interchangeably with standard 3300 XL probes?

A2: No, the 3300 NSv probes are optimized for small machines and have different calibration factors compared to XL probes.

Q3: What type of driver is required for this probe?

A3: It must be paired with the 3300 NSv Proximitor Sensor driver, as it is specifically tuned for NSv probes.

Q4: How does cable length affect measurement accuracy?

A4: The probe, extension cable, and driver are factory-matched. Using incorrect lengths or mismatched components can cause measurement errors.

Q5: What is the maximum target material thickness required?

A5: The conductive target should be at least 1 mm thick for accurate measurement, typically steel or similar alloys.

Q6: Is shielding required for the probe cable?

A6: Yes, the coaxial design includes shielding to minimize electromagnetic interference.

Q7: What frequency response range is supported by this probe?

A7: It supports a linear response up to 10 kHz, suitable for most machinery vibration monitoring.

Q8: Can this probe operate in hazardous areas?

A8: Certain configurations are available with hazardous area approvals (ATEX/CSA/IECEx). Ensure proper certification before use.

Q9: How is linearity maintained in this probe?

A9: It is factory-calibrated with a 200 mV/mil scale factor, ensuring linear response across the standard measurement gap.

Q10: Can this probe be field-calibrated?

A10: No, it should not be field-calibrated. Accuracy is ensured by using factory-matched probe, cable, and driver sets.
