Eddy-Current Probe Scaling and Rotor Dynamics

The 330101-00-50-10-02-00 operates as an eddy-current transducer requiring calibration to a scaling factor of 7.87 V/mm (200 mV/mil). During installation, the gap voltage must be validated against the -10 VDC target midpoint to ensure linear operation within the specified measurement range. Maintaining this precise gap is necessary for accurate observation of rotor dynamics, including shaft centerline positioning and orbital vibration. Proper physical spacing between adjacent probes is mandatory for effective cross-talk suppression and signal integrity within the machine monitoring network.

Frequently Asked Questions

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

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, which introduces non-linearity and significant measurement errors.

Q: How is the probe case protected against corrosion?

A: The probe body is constructed from AISI 303 or 304 stainless steel, providing high mechanical strength and corrosion resistance suitable for industrial machinery environments.

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 case is electrically conductive; verify the installation bracket is bonded to the machine housing to maintain electromagnetic immunity.
• Connector Integrity: Utilize the ClickLoc connector mechanism for all coupling points. Clean the mating faces with an approved electrical contact cleaner prior to assembly.
• Cable Routing: Route coaxial cables through dedicated metallic conduit, maintaining physical separation from high-voltage AC lines to prevent induced noise on the output signal.
