EPRO Eddy Current Measurement Technology
The PR6426/010-140 probe operates by generating an electromagnetic field at the probe tip and detecting impedance changes caused by movement of a conductive target. The CON011/91 converter supplies the probe excitation signal, demodulates the returned high-frequency signal, and provides a conditioned output for machinery monitoring channels.
The measurement chain requires correct probe installation, target material compatibility, and cable routing control to maintain signal stability. The eddy current loop is normally applied for shaft relative displacement measurement, axial position monitoring, and rotor dynamic analysis.
Frequently Asked Questions
Q: What measurement principle is used by the PR6426/010-140 probe?
A: The PR6426/010-140 uses an eddy current measurement principle. The probe detects changes in electromagnetic field coupling caused by the distance variation between the sensor tip and the conductive target surface.
Q: What function does the CON011/91 converter perform in the measurement chain?
A: The CON011/91 provides signal conditioning for the eddy current probe. It processes the high-frequency carrier signal and converts the probe response into a proportional output suitable for machinery monitoring systems.
Q: What installation factors affect measurement accuracy?
A: Probe gap adjustment, target material characteristics, cable shielding, and electromagnetic interference control affect the stability and accuracy of the displacement measurement loop.
Field Installation Guidelines
Install the PR6426/010-140 probe with the sensing face aligned to the target surface according to the mechanical drawing requirements. Maintain proper probe gap adjustment to achieve the specified electrical operating range.
Use shielded coaxial connections between the probe and converter. The cable shield should follow the system grounding requirements to reduce electromagnetic interference.
Keep sensor wiring separated from high-voltage power cables, motor supply lines, and switching circuits. Verify signal polarity, connector condition, and converter channel configuration before commissioning.
Confirm the measurement output against the machinery monitoring system input range before placing the protection channel into operation.
