PR6423/010-040 | EPRO | 8mm Eddy Current Sensor

Configured for non-contact shaft displacement monitoring, the EPRO PR6423/010-040 (PR6423/010-040) 8mm Eddy Current Sensor with 10 Meters Extension Cable provides direct physical execution of proximity detection for rotating machinery.

Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The PR6423/010-040 utilizes eddy-current induction to measure the relative position of conductive shafts. Accurate rotor dynamics analysis depends on precise eddy-current probe scaling; the sensor must be calibrated to the specific magnetic properties of the target material to maintain a linear output. During commissioning, gap voltage validation—specifically targeting the nominal -10 VDC center point—is mandatory to ensure the probe remains within its linear operating range. To maintain signal integrity in multi-probe TSI configurations, maintain proper spacing between adjacent sensor tips to achieve cross-talk suppression and eliminate interference between high-frequency oscillator fields.

Frequently Asked Questions

Q: Can the 10-meter extension cable be modified or shortened on-site?

A: No. The extension cable is a factory-tuned component of the resonant oscillator circuit. Modifying the cable length changes the circuit impedance and capacitance, which directly impacts the measurement sensitivity and frequency response.

Q: Is the sensor compatible with existing non-EPRO signal converters?

A: Compatibility is dependent on matching the oscillation frequency and input impedance of the signal converter to the PR6423 probe specifications. Ensure the signal converter excitation frequency and impedance match the factory requirements to prevent measurement non-linearity.

Field Installation Guidelines

1. Secure the probe in a rigid mounting bracket to prevent mechanical resonance, which can introduce artificial vibration signals into the monitoring system.
2. Verify the initial air gap using a calibrated feeler gauge during static shaft positioning to achieve the target gap voltage.
3. Terminate the shield of the extension cable at the monitoring system terminal block; ensure the shield does not touch the machine housing to avoid ground loop current paths.
4. Route the cable through grounded metallic conduit, keeping it physically separated from high-power AC motor leads or VFD cables to minimize electromagnetic noise coupling.
5. Confirm that the probe tip is perpendicular to the shaft surface; any angular misalignment will distort the displacement signal and compromise measurement accuracy.
