Eddy-Current Probe Scaling & Gap Voltage Validation

The probe operates on eddy-current scaling principles where target material conductivity and permeability directly influence output slope. Calibration is fixed at factory-set sensitivity of 7.87 mV/μm (200 mV/mil). Gap voltage validation targets -10 VDC when installed against a standard steel target at nominal probe gap. Cross-talk suppression is achieved through precise shielding termination and separation from unrelated signal conductors.

Frequently Asked Questions

Q: Can the 330101-00-08-05-02-00 be used with non-steel targets?

A: Yes, but scaling factors will change; re-calibration is required to maintain accuracy.

Q: Is hot-swapping supported during machinery operation?

A: No. Always de-energize the transducer system before replacing probes to prevent transient signal errors.

Q: What is the minimum bending radius for the standard cable?

A: Maintain a bend radius of no less than 25 mm to avoid coaxial impedance changes.

Field Installation Guidelines

Install probe tip perpendicular to the conductive target surface with 0.0 in unthreaded length engaged fully into the mounting bracket. Torque to 3.4 N·m (30 in-lb) maximum. Ground the shield at the system driver end only. Route the probe cable separately from power conductors to prevent inductive interference. Verify gap voltage after installation using the driver monitor output.
