Function:Non-contact eddy current probe,detect shaft relative vibration and axial displacement.Convert gap change into voltage signal,transmit signal to preamplifier and TSI monitor for displacement calculation,alarm and rotating machinery fault diagnosis.

Installation:Thread mounting on bearing housing.Keep proper gap between probe tip and shaft target.Connect probe cable to CON021 preamplifier.

Interface:

‑8mm stainless steel probe tip

‑10m stainless steel armored signal cable

‑M12 connector for preamplifier connection

Circuit feature:High stability coil design,wide frequency response,oil and high temperature resistant,anti-electromagnetic interference for turbomachinery harsh environment.

Feature:EPRO PR6423 series 8mm eddy current probe,/01=8mm standard probe,0=10m armored cable,-140=M12 connector.Must use matched CON021 preamplifier as full measuring set. Common faults:cable armor damage,coil aging,connector pin corrosion.Confirm matched preamplifier before replacement.

Diagnostic:Sensor fault causes abnormal gap voltage,loss of shaft vibration/displacement reading,trigger TSI machinery protection alarm.

Built‑in function

PR6423/010-140 measures shaft radial vibration and axial displacement for rotating machinery protection,widely used for power plant TSI spare replacement.

Product Brief

PR6423/010-140 belongs to EPRO eddy current probe family,8mm standard probe with 10m armored cable and M12 connector. Must be used with calibrated matching CON021 preamplifier. Verify probe and preamplifier matching before ordering. Check cable continuity and gap voltage during commissioning. Widely applied for steam turbine,compressor and generator condition monitoring. ESD anti‑static protection shall be followed during installation.
