Product Introduction
The Epro PR6423/00R-111+CON041 8mm Eddy-Current Sensor is a high-precision proximity sensor designed for continuous, non-contact measurement of shaft vibration and displacement in rotating machinery. It operates on the eddy-current principle, ensuring accurate detection of metallic surface movements even under harsh industrial conditions. This sensor, when used with the CON041 converter, provides a reliable and linear voltage output proportional to the gap distance, making it suitable for critical condition monitoring in turbines, compressors, and motors.

FAQ
Q1: How does the PR6423/00R-111 sensor detect vibration or displacement?
A1: It operates on the eddy-current principle, generating a magnetic field that induces eddy currents in the metallic target surface. The amplitude of these currents changes with the distance, allowing precise non-contact displacement measurement.
Q2: What type of converter is required with this sensor?
A2: The PR6423/00R-111 is designed to work with the Epro CON041 converter, which linearizes and scales the sensor output for integration into monitoring systems.
Q3: Is the sensor output signal linear across the full range?
A3: Yes, the output is highly linear (±1% typical) across the specified measuring range when properly calibrated with the correct converter.
Q4: Can the sensor be used in high-temperature environments?
A4: Yes, the sensor operates reliably up to +180°C and can be used in thermally demanding applications with appropriate cabling.
Q5: How is electromagnetic interference minimized?
A5: The sensor and cable assembly are fully shielded, and differential signal transmission minimizes noise from external EMI sources.
Q6: Is the PR6423/00R-111 compatible with other monitoring systems?
A6: Yes, it provides an analog voltage output compatible with most industrial condition monitoring and protection systems that accept standard signal inputs.
Q7: What materials are suitable as targets for this sensor?
A7: It is optimized for ferromagnetic materials such as steel or iron but can also measure non-ferromagnetic conductive metals with minor calibration adjustments.
Q8: How is the probe calibrated with the CON041 converter?
A8: Calibration involves setting the nominal gap and verifying linear output across the working range using a reference metallic surface and adjustment tools provided by Epro.
Q9: What is the sensor’s response time to rapid shaft movement?
A9: The sensor features a fast response frequency up to 10 kHz (-3 dB), allowing accurate capture of dynamic shaft behavior.
Q10: Can multiple sensors be installed close to each other without interference?
A10: Yes, but they must be spaced according to Epro’s installation guidelines to prevent cross-coupling between their magnetic fields.
