System compatibility:Works with PR6422/PR6423/PR6424/PR6425/PR6426 eddy current probes,support MMS6000 TSI monitoring system,for steam turbine,compressor and generator shaft radial vibration,axial displacement measurement.

Function:Process weak signal from eddy current probe,linearize and amplify signal. Output composite voltage signal containing static gap DC value and dynamic vibration AC value,send signal to TSI monitoring module for calculation,alarm and protection interlock.

Installation:Din rail mounting in cabinet. Lemo port connect eddy current probe,terminal block for -24V power and signal output.

Interface:

‑Lemo coaxial connector for eddy current probe

‑Screw terminals for DC power and signal output

‑Din rail fixed mounting foot

Circuit feature:Built-in high stability signal conditioning circuit,with short circuit,open circuit and reverse polarity protection,strong anti-interference.

Feature:EPRO classic eddy current preamplifier,IP20 indoor cabinet use,Lemo plug connection. Must be matched with corresponding PR642X probe. Common faults:internal circuit aging,connector pin corrosion,signal drift. Confirm full sensor model before replacement.

Diagnostic:Preamplifier fault leads to abnormal gap voltage,loss vibration signal,TSI channel alarm.

Built‑in function

CON021 converts eddy current probe raw signal into standard measurable voltage,widely used for power plant rotating machinery TSI system spare replacement.

Product Brief

CON021 belongs to EPRO eddy current sensor spare parts family,compact din rail preamplifier for PR6426 series eddy current probe. Verify probe model and TSI card compatibility before ordering. Check gap voltage and signal output during commissioning. Widely applied for steam turbine,compressor and generator condition monitoring. ESD anti‑static protection shall be followed during installation.
