Eddy-Current Probe Scaling and Rotor Dynamics Characteristics

The 330901-00-40-10-02-05 uses eddy-current measurement technology to convert shaft displacement into proportional electrical signals. The probe provides an average scale factor of 7.87 V/mm (200 mV/mil), allowing the connected 3300 XL NSv Proximitor Sensor to process dynamic vibration and position signals.

Furthermore, the probe design supports rotor dynamics monitoring by measuring radial vibration, radial position, axial thrust position, tachometer signals, zero speed conditions, and Keyphasor phase reference signals. The narrow side-view structure reduces installation limitations where standard 3300 and 3300 XL 5 mm or 8 mm transducer systems cannot fit.

The probe also supports gap voltage validation through the standard eddy-current transducer measurement method. Proper gap voltage adjustment enables accurate target detection and stable displacement measurement.

Frequently Asked Questions

Q: What type of target applications does the 330901-00-40-10-02-05 support?
A: The probe supports small target measurements, including radial vibration monitoring on shafts smaller than 51 mm (2 in) and axial position measurement on flat targets smaller than 15 mm (0.6 in).

Q: Can the 330901-00-40-10-02-05 replace older 3300 RAM or 3000-series systems?
A: The 3300 XL NSv Transducer System can replace 3300 RAM and 3000-series or 7000-series 190 Transducer Systems. However, system upgrades may require replacement of the probe, extension cable, and Proximitor Sensor depending on the existing configuration.

Q: What installation condition requires the NSv probe design?
A: The NSv probe design fits applications with counter bore, side-view, or rear-view restrictions that prevent installation of standard proximity transducer systems.

Field Installation Guidelines

Install the 330901-00-40-10-02-05 probe according to the mechanical clearance requirements of the monitored machine. Verify that the 1/4-28 UNF threaded mounting location provides correct probe alignment with the shaft or target surface.

Route the miniature coaxial cable away from high-current power wiring, ignition sources, and strong electromagnetic interference areas. Maintain proper cable support to prevent mechanical stress on the ClickLoc connector.

Before operation, adjust the probe gap according to the connected 3300 XL NSv Proximitor Sensor requirements. Confirm the gap voltage output and verify the target surface condition before collecting vibration or position data.

For TSI applications, verify probe orientation, target geometry, and signal polarity before commissioning rotor vibration, axial position, or Keyphasor measurement channels.
