System compatibility:Matches EPRO MMS6000 TSI monitoring system,used for steam turbine,compressor and generator large diameter shaft(≥80mm) radial vibration and axial displacement measurement.

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 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 ±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 M18×1.5 threaded probe head

‑3m armored PTFE integrated cable

‑Lemo coaxial connector

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

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

Feature:EPRO complete 16mm eddy current measuring chain,3m armored cable version,designed for large rotating metal shaft. Larger probe tip requires bigger metal target surface. 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

PR6424/003-030+CON021 eddy current sensor assembly collects shaft vibration and displacement data for heavy rotating machinery protection,widely used for power plant TSI spare replacement.

Product Brief

PR6424/003-030+CON021 belongs to EPRO eddy current sensor spare parts family,complete measuring chain including 16mm probe and CON021 preamplifier. Verify TSI monitoring card compatibility before ordering. Check cable insulation,probe coil and preamplifier output function during commissioning. Widely applied for large steam turbine,compressor and generator condition monitoring. ESD anti‑static protection shall be followed during installation.
