The Emerson PR6426/000-131 non-contact eddy current sensor operates in combination with the CON041/916-200 signal converter to form a proximity measurement system for heavy industrial turbomachinery. Engineered for deployment on steam, gas, and hydro turbines, as well as compressors, pumps, and fans, this assembly measures radial and axial shaft displacement, position, eccentricity, and motion. The PR6426/000-131 sensor monitors physical shaft proximity without direct contact, while the CON041/916-200 converter processes these variables into normalized electrical outputs suitable for continuous machinery protection networks.
