EPRO CON041+PR6424/006-131 Eddy Current Sensor System
The EPRO CON041+PR6424/006-131, also cataloged as the CON041 Signal Converter with PR6424/006-131 Eddy Current Probe, operates as a dedicated hardware component for non-contact shaft vibration and displacement measurement within machinery protection platforms. The dual-component hardware loop senses physical gaps between the 5 mm probe tip and rotating shaft targets, translating mechanical movement into linearized proportional current and voltage outputs via the CON041 module.

Eddy-Current Probe Scaling and Gap Voltage Validation
The assembly relies on exact eddy-current probe scaling to guarantee an Incremental Scale Factor (ISF) of 8 V/mm when tracking ferromagnetic targets. During field setup, engineers perform gap voltage validation to position the 5 mm probe at the 0.5 mm initial air gap, targeting a precise negative DC voltage offset at the converter terminal block. This prevents signal saturation from dynamic rotor dynamics. In multi-probe arrangements, the design exhibits high cross-talk suppression, maintaining measurement integrity inside dense bearing housings.
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 be mounted directly on the machine housing alongside the probe?
A: No. The converter has a maximum operating limit of +85 deg C and must be mounted in a field junction box on a DIN rail or panel, whereas the PR6424/006-131 probe tip can withstand up to +180 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
- Target Area Inspection: Verify that the target area on the rotating shaft is free of scratches, tool marks, and localized magnetic runout to prevent measurement distortion.
- Gap Voltage Tuning: Thread the probe into the mounting bracket while measuring the converter output, locking the jam nuts only when the baseline gap voltage is stabilized.
- Coaxial Connection Protection: Protect the connection point between the probe cable and the extension cable with self-amalgamating tape to seal out oil, water, and contaminants.
- Shield Grounding: Ensure the coaxial cable shield is grounded only at the CON041 converter side to prevent ground loops from corrupting the raw high-frequency signals.
