Emerson Epro PR6426/010-110 Eddy Current Displacement Sensor

The Emerson Epro PR6426/010-110, also cataloged as the PR6426 Eddy Current Displacement Sensor, operates as a dedicated hardware component for non-contact shaft vibration, axial displacement, and position measurement within machinery protection systems.

Hardware Specifications

Rotor Dynamics & Gap Voltage Validation

Proper operation requires precise physical positioning and gap voltage validation relative to the target shaft. When coupled with CON021 or CON041 signal converters, setting the recommended DC gap offset ensures linear response up to 10 kHz and effective cross-talk suppression during dynamic rotor shaft motion.

Frequently Asked Questions

Q: Which signal converter modules are compatible with the PR6426/010-110?

A: The probe integrates directly with CON021 or CON041 signal converters to generate standardized analog output signals.

Q: Can the 10-meter integrated cable be shortened or spliced during field wiring?

A: No, trimming or splicing the integrated 10-meter cable alters system inductance and capacitance, which invalidates the factory-calibrated sensitivity.

Field Installation Guidelines

• Ensure a minimum of 5 full threads of engagement when securing the threaded body into the machine housing port.
• Route the integrated 10-meter sensor cable through grounded metal conduit away from high-voltage motor lines and variable frequency drive (VFD) circuits to prevent signal degradation.
• Verify that signal cable shielding is grounded at a single termination point (typically at the converter module housing) to eliminate electrical ground loops.
• Use a feeler gauge or monitor DC gap voltage with a digital multimeter prior to final locknut tightening to establish proper mid-range mechanical clearance.
