Emerson EPRO PR642300R-000 Eddy Current Probe

Product Brief Introduction PR642300R-000 is EPRO eddy current displacement probe, used for non-contact shaft vibration and shaft position measurement on rotating machinery.
Tag:

Technical Specifications Eddy current type; 8mm probe diameter; matched with CON series converter; measuring range 0~2mm; operating temperature -40~180°C.

Functional Features Non-contact displacement measurement. Measure shaft radial vibration and axial position. High temperature resistance for turbine and compressor.

Application Scenarios Steam turbine, gas turbine, centrifugal compressor, generator, rotating machinery vibration monitoring and protection system.

Performance Parameters High frequency response; Non-contact measurement, no wear; Linear displacement output.

Structural Characteristics Metal probe tip, stainless steel probe body, integrated coaxial cable, thread for mounting into probe bracket.

Working Principle High frequency alternating current creates eddy current on metal shaft surface. Impedance of probe coil changes with distance between probe and shaft, converted to voltage signal by the converter.

Installation Requirements Install probe into probe holder, adjust air gap to mid-range. Connect coaxial cable to EPRO converter. Calibrate gap voltage.

Usage Notes Protect probe cable from pulling and abrasion. Avoid metal debris near probe tip. Perform gap calibration before commissioning.
