EPRO CON041+PR6424/002-031 Eddy Current Sensor System
The EPRO CON041+PR6424/002-031 serves as the primary CON041 Signal Converter with PR6424/002-031 Eddy Current Probe utilized to execute non-contact shaft vibration and displacement measurement across machinery protection platforms. The dual-component hardware configuration processes raw high-frequency electromagnetic impedance variations at the 5 mm probe tip, translating physical mechanical gaps into linearized current or voltage outputs. This sensor-to-converter link provides direct physical/electrical signal conditioning to interface with host PLC or DCS monitoring backplanes.

Eddy-Current Probe Scaling and Gap Voltage Validation
The measurement loop relies on highly accurate eddy-current probe scaling to ensure a linear output of 8 V/mm across the physical 2 mm operating range. Technicians must conduct gap voltage validation during the physical alignment process, adjusting the 5 mm probe body relative to the target until the baseline output voltage of the CON041 converter stabilizes at its designated negative voltage target. This accurate calibration sequence counteracts dynamic rotor dynamics during startup and load cycles, while the internal shielding configuration guarantees high cross-talk suppression between adjacent probe lines.
Frequently Asked Questions
Q: How does the CON041 converter signal a field wiring fault or sensor open circuit?
A: The converter features built-in diagnostics that monitor the sensor loop health, driving the 4-20 mA output current below 3.6 mA to indicate a broken cable or disconnected sensor.
Q: Can the CON041 converter module be installed in the same high-temperature environment as the PR6424/002-031 probe?
A: No. The PR6424/002-031 probe tip is rated for up to +180 deg C, whereas the CON041 converter housing contains active processing circuitry and must be installed in a cooler area with ambient temperatures between -35 and +85 deg C.
Q: Is it possible to transmit both the voltage and current outputs of the converter simultaneously to different receiver cards?
A: Yes, the CON041 module provides independent physical terminals for the 4-20 mA DC loop and the +/-10 V DC output, allowing parallel signal routing to separate measurement devices.
Field Installation Guidelines
- Probe Gap Adjustment: Slowly screw the PR6424/002-031 probe into the threaded mount while monitoring the analog voltage output until the physical air gap matches the calibrated 0.5 mm baseline.
- Cable Protection: Encase the PTFE coaxial probe cable within flexible conduit to shield the run from mechanical crushing and fluid contamination.
- Grounding Protocol: Maintain single-point grounding by connecting the extension cable shield strictly at the CON041 converter terminal block and keeping the probe housing isolated from the machine frame.
- Avoid High-Voltage Paths: Route the signal cables away from high-current AC motor leads or switching frequency drives to prevent electromagnetic noise from distorting the analog outputs.
