EPRO CON041+PR6423/009-031-CN Eddy Current Sensor System
Configured for non-contact shaft vibration and displacement measurement in machinery protection systems, the EPRO CON041+PR6423/009-031-CN (CON041 Eddy Current Sensor System) provides direct physical/electrical execution. The hardware assembly pairs an 8 mm probe head with an integrated signal conditioner, processing electromagnetic impedance transitions into linearized analog signals. This system directly links mechanical shaft dynamics to supervising monitoring networks without physical contact.

Eddy-Current Probe Scaling and Gap Voltage Validation
The dual-component hardware loop uses precise eddy-current probe scaling to guarantee an Incremental Scale Factor (ISF) of 8 V/mm across the physical 2 mm operating range. Technicians perform gap voltage validation during physical commissioning, adjusting the 8 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 handle cabling fault diagnostics?
A: The converter continuously evaluates circuit impedance, driving the 4-20 mA current output below 3.6 mA to signal a broken sensor wire or short-circuit condition immediately to the master system.
Q: Can the CON041 converter module be installed in the same high-temperature environment as the PR6423/009-031-CN probe?
A: No. The PR6423/009-031-CN 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 the system output compatible with simultaneous voltage and current logging?
A: Yes, the CON041 features separate output terminals allowing both the 4-20 mA DC loop and the +/-10 V DC signal to be wired in parallel to separate monitoring or PLC/DCS input modules.
Field Installation Guidelines
- Probe Gap Adjustment: Slowly screw the PR6423/009-031-CN 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.
