Emerson EPRO PR6480/061-030+C0N021 Eddy Current Signal Converter

Product Description

The PR6480/061-030 + CON021 is a high-precision sensor signal converter designed for critical turbomachinery monitoring. This German-engineered device acts as the "driver" for eddy current probes, converting raw high-frequency signals into standardized voltage outputs. It is a vital component for measuring radial and axial shaft displacement, position, eccentricity, and speed/key in steam, gas, and hydro turbines, as well as high-speed compressors and pumps. The combination of the PR6480 series converter and the CON021 signal conditioner ensures high-speed data acquisition with a rise time of less than 15 μs.

Key Engineering Features

• High-Speed Dynamic Response: With a frequency range up to 20 kHz and a microsecond-level rise time, the converter is capable of capturing rapid shaft vibrations and high-speed "key" pulses for precise phase analysis.

• Flexible Output Scaling: Supports multiple negative voltage output ranges (e.g., -2V to -18V or -4V to -20V), allowing for seamless integration with various Rack Monitoring Systems (RMS) and Data Acquisition hardware.

• Precision Signal Conditioning: The integrated CON021 unit provides the necessary excitation for the eddy current probe and linearizes the return signal, ensuring high accuracy over the entire measurement range.

• Industrial Ruggedness: Designed to withstand mechanical stress, featuring shock and vibration resistance of 5g at 60 Hz, making it suitable for mounting in cabinets near heavy rotating machinery.

• Compact Lightweight Design: At only 120 grams and featuring a specialized aluminum alloy housing, the module is easy to install in high-density DIN-rail or rack configurations.
