Function:Non-contact real-time detection of rotating shaft vibration and axial displacement.Convert gap variation between probe and metal shaft into weak coil signal,send signal to CON021 preamplifier for signal conditioning,then transmit to MMS series monitoring module for alarm and protection interlock.

Installation:Thread mounting installation on bearing housing,adjust air gap within linear range.Connect Lemo coaxial connector to CON021 preamplifier.

Interface:

‑Stainless steel threaded probe head

‑3m armored PTFE integrated cable

‑Lemo coaxial connector for preamplifier connection

Circuit feature:High stability built-in measuring coil,high temperature resistant armored cable,strong anti-interference for industrial harsh environment.

Feature:EPRO PR6423 series 8mm probe,3m cable,CN calibrated version,±1mm linear range. High measuring precision. Common faults:cable breakage,coil aging,Lemo connector corrosion. Confirm full model and matched preamplifier before replacement.

Diagnostic:Sensor failure causes abnormal gap voltage,TSI channel alarm,losing shaft vibration and displacement monitoring.

Built‑in function

PR6423/003-030-CN eddy current probe collects shaft vibration and displacement data for rotating machinery protection,widely used in power plant TSI spare replacement.

Product Brief

PR6423/003-030-CN belongs to EPRO eddy current sensor spare parts family,8mm probe with 3m armored cable,CN domestic calibrated version,must be matched with CON021 preamplifier. Verify preamplifier and TSI card compatibility before ordering. Check cable insulation and probe coil function during commissioning. Widely applied for steam turbine,compressor and generator condition monitoring. ESD anti‑static protection shall be followed during installation.
