EPRO PR6423/097-110 Eddy Current Proximity Sensors

Configured for shaft position, axial displacement, and dynamic relative vibration processing in industrial machinery protection platforms, the EPRO PR6423/097-110 (PR6423 Eddy current sensor) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

The PR6423 non-contact displacement sensor platform uses structured order suffixes to designate thread sizes, body configurations, and cable configurations:

• PR6423: Base 8 mm tip diameter eddy current transducer series designed for contactless gap and vibration monitoring.
• /097-110: Specific hardware options designating metric/imperial mounting threads, case construction features, armored or unarmored cable options, and cable length terminations for matching CON series signal conditioners.

Hardware Specifications

Eddy-Current Probe Scaling & Gap Voltage Validation

The EPRO PR6423/097-110 functions via high-frequency eddy-current probe scaling to measure non-contact static distance and high-speed dynamic shaft motion against ferromagnetic target surfaces. Electromagnetic energy radiated from the 8 mm tip induces eddy currents in the target material, yielding a linear output voltage proportional to physical gap changes.

During field configuration, gap voltage validation targets a nominal -10 VDC baseline at the center of the calibrated 2.0 mm linear range. Proper physical spacing and matching driver impedance provide critical cross-talk suppression between orthogonal x-y probe pairs mounted in turbo-machinery bearing housings, preventing mutual inductive coupling from affecting rotor dynamics monitoring accuracy.

Frequently Asked Questions

Q: How is the physical mounting gap set for the PR6423/097-110 sensor during installation?

A: The probe body is threaded toward the shaft until the static output voltage from the connected signal conditioner reaches the nominal center-scale value, typically -10 VDC.

Q: What precautions should be taken regarding the extension cable connections?

A: Interconnecting connectors between the PR6423 sensor cable and the extension cable must be insulated from metallic conduit and machine housing using insulating sleeves or heat-shrink tubing to prevent unwanted ground contacts.

Field Installation Guidelines

1. Mount the sensor tip perpendicular to the observed shaft target surface using threaded mounting ports or rigid brackets.
2. Monitor the driver output voltage while adjusting thread engagement to achieve the target gap voltage (nominally -10 VDC).
3. Secure the probe using jam nuts tightened to specified torque ratings to avoid mechanical drift under operational vibration.
4. Route extension cables in dedicated grounded flexible conduit, keeping signal paths clear of high-voltage supply lines.
