EPRO CON021/916-200 Eddy Current Signal Converter

The EPRO CON021/916-200, also cataloged as the CON021/916-200 Eddy Current Signal Converter, operates as a dedicated hardware component for radial and axial shaft displacement, position, eccentricity, and speed signal conditioning within turbo machinery monitoring systems.

Hardware Specifications

Eddy-Current Probe Scaling & Gap Voltage Validation

The CON021/916-200 processes high-frequency signals generated by the paired PR6426 probe tip to measure displacement across an extended 20.0 mm dynamic range. Onboard signal processing scales eddy-current probe impedance variations into a linear -4 V to -20 V DC voltage output across a 0 to 20000 Hz frequency response spectrum. During mechanical setup, accurate gap voltage validation must be conducted to establish the baseline DC bias voltage, ensuring linear signal representation of dynamic rotor dynamics while maintaining cross-talk suppression relative to adjacent structural elements.

Frequently Asked Questions

Q: What power input range is required to energize the CON021/916-200 converter?

A: The module requires a nominal negative DC power supply ranging from -23 V DC to -32 V DC.

Q: What wire gauge capacity do the connection terminals support?

A: The screw terminal blocks accept conductors up to a maximum cross-section of 1.5 mm2 fitted with wire-end sleeves.

Field Installation Guidelines

• Mount the unit using four M5x20 screws in a protective cabinet enclosure to satisfy IP20 environmental constraints.
• Ensure power supply conductors and probe signal leads are terminated with wire-end sleeves before clamping into the screw terminals.
• Route sensor input cables separately from high-voltage AC lines to prevent signal distortion across the 0 to 20000 Hz frequency spectrum.
• Verify proper earth grounding of the signal conditioner frame to avoid ground loop noise during high-speed shaft measurement.
