Eddy-Current Probe Scaling and Rotor Dynamics

The 330102-00-40-10-01-05 transducer operates on the eddy-current principle, requiring a calibrated scale 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 displacement range. Proper gap adjustment is mandatory for accurate analysis of rotor dynamics, including shaft centerline positioning and orbital vibration. Physical spacing between adjacent probes must be maintained to provide effective cross-talk suppression and ensure signal integrity in multi-channel monitoring systems.

Frequently Asked Questions

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

A: No. The 330102 system is factory-calibrated as a matched set including the probe, extension cable, and Proximitor sensor. Field-modifying the cable length alters the electrical impedance and will introduce significant measurement errors.

Q: Does the Viton O-ring provide a certified high-pressure seal?

A: The Viton O-ring is designed for differential pressure sealing at the probe tip; however, the unit is not pressure-tested as part of the standard manufacturing process. Contact the manufacturer for requirements involving high-pressure process fluid environments.

Field Installation Guidelines

• Mounting: Secure the probe in a rigid, non-conductive bracket. Ensure 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 compatibility (EMC).
• Connector Integrity: Use the ClickLoc connector mechanism for all coupling points. Ensure mating surfaces are clean and free of debris prior to assembly to prevent signal attenuation.
• Cable Routing: Route coaxial cables through dedicated metallic conduit, maintaining physical separation from high-voltage AC lines to prevent induced noise on the displacement signal.
