Eddy-Current Probe Scaling & Gap Voltage Validation

The probe operates on eddy-current inductive scaling with a linear range defined by the target material’s electromagnetic properties. For optimal rotor dynamics measurement accuracy, maintain a gap voltage near -10 VDC at installation. Cross-talk suppression is achieved through precision shielding and controlled cable routing to minimize capacitive coupling between adjacent probes.

Frequently Asked Questions

Q: Can this probe be hot-swapped in an energized system?

A: No. Always de-energize the monitoring module before connecting or disconnecting the probe to prevent transient voltage damage.

Q: What is the effect of incorrect unthreaded length installation?

A: Improper positioning may shift the probe outside its calibrated linear range, reducing measurement accuracy and risking signal saturation.

Q: Does the miniature coaxial ClickLoc connector require torque specification during mating?

A: Yes. Finger-tighten only; over-torquing can deform the connector interface and degrade RF shielding performance.

Field Installation Guidelines

Mount the probe using the 3/8-24 UNF thread, ensuring full engagement without inducing mechanical stress on the case. Maintain proper standoff from the rotating surface within the specified gap range. Route the cable away from high-voltage conductors and secure it with non-metallic clamps to preserve signal integrity. Terminate the shield at the monitoring system ground point to control EMI ingress.
