System compatibility:Matches EPRO MMS6000 TSI monitoring system,works for steam turbine,compressor and 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,send standard composite voltage signal to MMS series monitoring module for alarm and protection interlock.

Installation:Probe threaded mounting on bearing housing,adjust air gap within 0~2mm 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

‑130cm armored PTFE integrated cable

‑Lemo coaxial connector

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

Circuit feature:High stability coil design,high temperature armored cable;CON021 built-in signal conditioning circuit,with open circuit,short circuit and reverse polarity protection,strong anti-interference.

Feature:EPRO PR6423 complete measuring chain,130cm armored cable version,0~2mm linear range,with CON021 preamplifier,high measuring precision. Common faults:cable breakage,coil aging,Lemo connector corrosion. Confirm full complete model before replacement.

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

Built‑in function

PR6423/010-130+CON021 eddy current probe assembly collects shaft vibration and displacement data for rotating machinery protection,widely used for power plant TSI spare replacement.

Product Brief

PR6423/010-130 belongs to EPRO eddy current sensor spare parts family,8mm probe with 130cm armored cable,paired with CON021 preamplifier. Verify TSI monitoring card compatibility before ordering. Check cable insulation,probe coil and preamplifier output function during commissioning. Widely applied for steam turbine,compressor and generator condition monitoring. ESD anti‑static protection shall be followed during installation.
