System compatibility:Matches EPRO MMS6000 TSI monitoring system,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 weak coil signal,send signal to CON021 preamplifier for demodulation and amplification,output composite voltage signal for TSI monitoring module to execute alarm and protection interlock.

Installation:Probe threaded mounting on bearing housing,adjust air gap within linear range. Lemo coaxial connector links probe and CON021;CON021 DIN rail mounted in cabinet,wiring for -24V power and signal output.

Interface:

‑Stainless steel threaded probe head

‑1m armored PTFE integrated cable

‑Lemo coaxial connector

‑CON021 screw terminals for -24VDC power and signal output

Circuit feature:Built-in stable measuring coil,high temperature armored cable;CON021 signal conditioning circuit with open/short circuit and reverse polarity protection,strong anti-interference.

Feature:EPRO PR6423 series complete measuring chain,100cm cable,CN domestic calibrated version,matching CON021 preamplifier. High measuring precision,stable signal output. Common faults:cable damage,coil aging,Lemo connector corrosion. Use full complete model including CN suffix for compatibility confirmation before replacement.

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

Built‑in function

PR6423/010-000-CN+CON021 eddy current sensor assembly collects shaft vibration and displacement data for rotating machinery protection,widely used for power plant TSI spare replacement.

Product Brief
