System compatibility:Matching with EPRO MMS6000 TSI monitoring system,used for steam turbine,compressor and generator shaft radial vibration and axial displacement measurement.

Function:Non-contact eddy current probe detects the gap between probe and rotating metal shaft. The weak coil signal is sent to CON021 preamplifier for demodulation and amplification,output composite voltage signal containing static gap DC value and dynamic vibration AC value,send signal to TSI monitoring module for alarm and protection interlock.

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

Interface:

‑Stainless steel threaded probe head

‑Lemo coaxial connector between probe and preamplifier

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

Circuit feature:Probe built-in stable coil;CON021 integrated signal conditioning circuit,with open circuit,short circuit and reverse polarity protection,strong anti-interference.

Feature:Complete calibrated EPRO eddy current measuring chain,PR6423/001-000 probe paired with CON021 preamplifier,high measuring precision and high temperature resistance. Common faults:armored cable damage,coil aging,Lemo connector corrosion. Use full complete set model for compatibility confirmation before replacement.

Diagnostic:Measuring chain fault leads to abnormal gap voltage,TSI channel alarm,losing shaft vibration and displacement monitoring.

Built‑in function

PR6423/001-000+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

PR6423/001-000+CON021 belongs to EPRO eddy current sensor spare parts family,complete calibrated measuring chain including PR6423 probe and CON021 preamplifier. Verify compatibility with MMS6000 TSI monitor 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.
