System compatibility:Matches EPRO MMS6000 TSI monitoring system,works with CON010/CON021 preamplifier,used for steam turbine,compressor,generator shaft radial vibration and axial displacement monitoring.

Function:Non-contact real-time detection of rotating shaft vibration and axial displacement.Convert gap variation between probe and metal shaft into standard voltage signal,send signal to MMS series monitoring module for alarm and protection interlock.

Installation:Thread mounting installation on bearing housing,keep proper air gap(about 5.5mm) between probe tip and shaft surface,connect extension cable to preamplifier.

Interface:

‑Probe head with stainless steel thread

‑Integrated armored PTFE cable

‑Coaxial connector for connecting preamplifier

Circuit feature:High stability coil design,anti high temperature armored cable,strong anti-interference,suitable for harsh industrial site.

Feature:EPRO classic 8mm eddy current probe,140cm integrated cable,high measuring precision,wide temperature adaptability. Common faults:cable damage,coil aging,connector failure. Confirm full model and matched preamplifier before replacement.

Diagnostic:Sensor failure causes abnormal gap signal,TSI module alarm,losing shaft vibration/displacement monitoring.

Built‑in function

PR6426/010-140 eddy current probe collects shaft vibration and displacement data for rotating machinery protection,widely used in power plant TSI system spare replacement.

Product Brief

PR6426/010-140 belongs to EPRO eddy current sensor spare parts family,8mm probe with 140cm armored cable,needs to be used together with matching 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.
