Eddy-Current Probe Scaling & Gap Voltage Validation

This transducer operates via eddy-current physics, generating a dynamic electromagnetic field at the 5.0 mm probe tip to monitor target proximity. To establish matched electrical impedance, this 1.0-meter probe must connect to its paired Proximitor sensor using a compatible extension cable to achieve a completed 5.0-meter or 9.0-meter loop configuration. Correct mechanical alignment of the M8 thread is necessary to execute gap voltage validation, targeting a nominal -10 VDC baseline at the midpoint of the linear range. Maintaining these precise electrical parameters limits signal attenuation and ensures high cross-talk suppression during high-frequency shaft displacement and rotor dynamics monitoring.

Frequently Asked Questions

Q: What is the main difference between the 5mm probe (330173) and the standard 8mm probe (330171)?

A: The 5mm probe has a physically smaller tip diameter and an M8 x 1 thread, allowing it to be installed in tighter spaces or smaller threaded ports where standard 3/8-24 or larger probes cannot fit. However, it has a smaller linear range than standard 8mm probes.

Q: Can this unarmored standard cable be run directly through open cable trays in high-temperature environments?

A: Yes, the fluoropolymer-insulated coaxial cable is rated for up to +177 deg C. However, because it lacks a flexible stainless steel armor conduit, it should be protected from sharp physical edges, pinch hazards, and direct mechanical strain inside the routing pathways.

Field Installation Guidelines

  • Thread Mounting and Torque: Mount the probe using standard metric brackets. Do not exceed 4.5 N-m (40 in-lb) of torque when tightening the mounting locknuts on the M8 x 1 threads to avoid case deformation.
  • Gap Voltage Adjusting: Thread the probe toward the target surface while monitoring the Proximitor output with a digital multimeter until the gap voltage reads -10.0 VDC (the nominal electrical center of the linear calibration curve).
  • Connector Integrity: Connect the miniature coaxial ClickLoc terminals finger-tight to preserve core isolation. Ensure no moisture, oil, or conductive contaminants enter the connection housing prior to assembly.
