The Emerson PR6426/010-000 non-contact sensor combined with the CON021/916-160 signal converter forms an industrial eddy current measurement system optimized for critical turbomachinery applications, including steam, gas, and hydro turbines, compressors, pumps, and fans. The PR6426 eddy current sensor detects radial and axial shaft displacement, position, eccentricity, and motion under harsh operating conditions. The matched CON021/916-160 converter accurately processes these proximity metrics into reliable electrical signals required by machinery protection and TSI monitoring platforms.
