Eddy-Current Probe Scaling & Gap Voltage Validation

The probe utilizes high-frequency eddy-current technology to deliver precise linear voltage output proportional to target gap distance. Target calibration requires gap voltage validation targeting -10 VDC at the physical center of the linear range (typically corresponding to approximately 1.0 mm or 40 mils gap setting when referenced to an AISI 4140 steel target). The system exhibits strict eddy-current probe scaling to suppress channel-to-channel cross-talk and maintain flat frequency response characteristics across high-speed rotor dynamics monitoring loops.

Frequently Asked Questions

Q: What is the procedure for verifying the gap voltage during probe physical setup?

A: Connect the probe cable to the extension cable and Proximitor Sensor powered by -24 VDC. Measure the DC voltage between the Proximitor "Out" and "Com" terminals using a digital multimeter. Adjust probe thread engagement until the gap voltage reaches the nominal target of -10.0 VDC (corresponding to mid-span gap), then torque the mounting locknut.

Q: Can the 0.5 meter probe cable be spliced or shortened directly in the field?

A: No. Cutting or splicing the coaxial cable alters total system capacitance and inductance, causing total calibration failure and severe sensitivity deviations. Total system electrical length (0.5 meter probe paired with matching extension cable and Proximitor) must be strictly maintained.

Field Installation Guidelines

  1. Mechanical Mounting & Sealing: Thread the 3/8-24 UNF body into the tapped bracket or probe sleeve. Ensure minimum 5 full turns engagement. Verify that internal differential pressure seals are properly positioned when installing into pressurized machine casings.
  2. Connector Assembly: Crimp and lock the miniature coaxial ClickLoc connector. Ensure protective connector boots or silicone tape sealing are applied when installed in oil-mist or wet environments.
  3. Cable Routing & Shielding: Route cable clear of sharp machine edges and intense thermal sources exceeding +177 deg C. Maintain cable bend radius above 25.4 mm (1.0 in). Ensure the outer shield layer is bonded to safety earth ground at the machine casing entry point.
