Eddy-Current Probe Scaling and Gap Voltage Validation

Probe scale factor is factory-calibrated at 7.87 mV/μm (200 mV/mil) over the linear range. Gap voltage validation targets -10 VDC when installed against a standard steel target. System integration requires verification of probe standoff distance to ensure operation within the linear region. Cross-talk suppression between adjacent probes is achieved by maintaining minimum edge spacing per Bently Nevada installation guidelines.

Frequently Asked Questions

Q: Can the probe be replaced without recalibrating the system?

A: No. Replacement requires re-measuring the gap voltage and verifying scale factor alignment with the associated monitor module.

Q: Does this model support hot-swapping?

A: No. The probe is a passive sensor; however, system wiring must be de-energized before disconnecting to prevent transient signal errors.

Q: What is the maximum cable routing distance from probe tip to monitor input?

A: Total system extension should follow Bently Nevada limits for coaxial cable runs to avoid signal attenuation beyond specified tolerance.

Field Installation Guidelines

Mount the probe using proper thread engagement of at least five full turns into the machined housing. Maintain concentric alignment to the monitored shaft surface. Route the coaxial cable away from high-voltage conductors and secure shielding continuity to the DIN-rail or panel ground point. Verify connector mating by audible ClickLoc engagement before energizing the system.
