Working Principle:
The CON041 amplifies and conditions raw analog signals from EPRO eddy current proximity sensors (PR6422-PR6426 series), converting them into standardized 4-20mA current or ±10V voltage outputs. The converter processes signals from radial vibration probes and axial position (thrust) probes, providing accurate measurements of shaft displacement, position, eccentricity, and speed/key signals.

Advantages and Highlights:

• High accuracy (±0.5% FSO) for precision turbomachinery monitoring

• Fast response time (<1 ms) enables real-time protection

• Wide operating temperature range supports demanding environments

• Hot-swap capability minimizes downtime during maintenance

• DIN rail mounting simplifies installation and replacement

• Built-in diagnostics provide early warning of sensor faults

• Universal compatibility with EPRO sensor family and most 8mm eddy current sensors

• EMI filtering ensures clean measurements near VFDs and high-power equipment

Applicable Industries:
Power generation (steam and gas turbines), oil and gas (compressors), chemical processing (pumps), heavy industry (motors and generators), and general rotating machinery (gearboxes).

Model Series:
EPRO CON Series Signal Converters / PR6423 Series Eddy Current Proximity Transducer Systems

Installation Requirements:

• DIN rail mounting with tool-free installation

• Spring-cage terminals for rapid wiring

• 24V DC ±10% power supply

• Maximum cable length: 100 meters with standard shielded cable

• Up to 1-2 MHz operating frequency compatibility

Usage Precautions:

• Verify correct sensor compatibility (optimized for EPRO sensors; compatible with most 8mm eddy current sensors at similar frequencies)

• Factory calibrated for standard EPRO sensors; fine-tuning may be needed for specific gap ranges or custom applications

• Use 4-20mA output for long cable runs to PLCs (superior noise immunity)

• Use ±10V output for direct connection to data acquisition systems requiring higher resolution

• Ensure operating temperature within -20°C to +70°C range

• Maintain proper shielding for cable runs to preserve signal integrity

• Regular calibration verification recommended
