Eddy-Current Probe Scaling and Rotor Dynamics

The 330101-00-10-10-02-00 transducer utilizes the eddy-current principle, requiring a calibrated scale factor of 7.87 V/mm (200 mV/mil). During site commissioning, gap voltage validation against the -10 VDC target midpoint is mandatory to ensure linear operation. Precise gap setting is necessary for accurate analysis of rotor dynamics, including shaft centerline positioning and radial vibration magnitude. To maintain signal fidelity, physical separation between adjacent proximity sensors must be maintained to provide effective cross-talk suppression.

Frequently Asked Questions

Q: Is the 1.0 metre total system length field-adjustable?

A: No. The 330101 system is factory-calibrated as a matched assembly consisting of the probe, integral cable, and Proximitor sensor. Field-modifying the cable length alters the electrical impedance and resonant frequency, which will introduce measurement inaccuracies.

Q: Are these probes compatible with standard 3300 XL Proximitor sensors?

A: Yes, provided the system length (1.0 metre) matches the calibration of the Proximitor. Ensure that the Proximitor firmware and revision are compatible with the specific probe series.

Field Installation Guidelines

• Mounting: Secure the probe in a rigid, non-conductive bracket. Verify that the probe tip is perpendicular to the shaft surface to prevent measurement skew.
• Grounding: The probe housing is electrically conductive; verify the mounting bracket is bonded to the machine ground to maintain electromagnetic compatibility (EMC).
• Connector Integrity: Use the ClickLoc connector mechanism for all coupling points. Clean the mating faces with an approved electrical contact cleaner prior to assembly to prevent signal attenuation.
• Cable Routing: Route the coaxial cable through dedicated metallic conduit, maintaining physical separation from high-voltage AC lines to prevent induced noise on the output signal.
