Eddy-Current Probe Scaling and Rotor Dynamics

The 330102-00-28-10-02-05 utilizes an eddy-current principle for non-contact measurement, calibrated to a scaling factor of 7.87 V/mm (200 mV/mil). During 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 orbit, radial position, and vibration magnitude. When installing multiple probes on a single bearing housing, maintain adequate separation to ensure cross-talk suppression and prevent signal interference between channels.

Frequently Asked Questions

Q: Can the 1.0 meter total system length be modified in the field?

A: No. The system is calibrated as a matched set (probe, extension cable, and Proximitor sensor). Field-modifying the cable length will alter the electrical impedance and introduce measurement inaccuracies.

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

A: Yes, provided the system length matches the calibration of the Proximitor. Ensure the extension cable and probe are compatible with the specific Proximitor sensor firmware and revision.

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 errors.
• Grounding: The probe case is electrically conductive; verify the installation bracket is bonded to the machine ground to ensure electromagnetic compatibility (EMC).
• Connector Integrity: Use the ClickLoc connector mechanism and ensure mating surfaces are free of debris to prevent signal attenuation or intermittent connections.
• Cable Routing: Route the coaxial cable through shielded conduit, maintaining separation from high-voltage AC lines to prevent induced electromagnetic noise.
