Eddy-Current Probe Scaling and Gap Voltage Validation
The probe’s calibration constant is fixed at 7.87 mV/μm (200 mV/mil), ensuring stable linear range from 0.25 to 2.3 mm (10 to 90 mils) standoff. Gap voltage validation targets -10 VDC under static installation conditions. Cross-talk suppression is achieved by maintaining a minimum 50 mm separation between adjacent probes in multi-channel rotor dynamics monitoring arrays.
Frequently Asked Questions
Q: Can this probe be used with non-Bently Nevada driver modules?
A: Only when the driver matches the 3300 XL 8 mm system impedance and scaling characteristics; mismatched drivers will cause incorrect displacement readings.
Q: What is the effect of temperature on probe performance?
A: Temperature variation within -35 to +177 degC results in negligible scale factor drift due to factory thermal compensation.
Q: Is hot-swapping supported in live machinery protection systems?
A: Hot removal or insertion is not recommended; power down the associated monitor to prevent transient signal errors.
Field Installation Guidelines
Mount the probe using the 3/8-24 UNF thread, engaging at least five full threads into the mounting bracket. Maintain perpendicular alignment to the target surface within ±1 deg. Route the coaxial cable away from high-voltage AC conductors to minimize electromagnetic interference. Ground the shield at the driver module end only, leaving the probe end insulated. Verify gap voltage before final tightening to ensure it reads near -10 VDC.
