EPRO PR6423 Sensor Extension Cable 

Technical Specifications

Model:PR6423 extension cable

Brand:EPRO(Emerson)

Cable type:Armored coaxial cable

Insulation material:PTFE

Outer protection:Stainless steel metal armor

Connector:Lemo 1S coaxial plug for probe / preamplifier

Available length:1m,3m,4m,5m,8m,10m optional

Min bending radius:35mm

Operating temperature:-20~+180℃

Cable outer diameter:6mm

Certification:CE

System compatibility:Special cable for EPRO PR6423 series eddy current probe,matched with CON021 preamplifier,used for steam turbine,compressor,generator shaft vibration and axial displacement monitoring.

Function:Transmit weak high-frequency eddy current signal between probe and CON021 preamplifier. Metal armored shielding prevents electromagnetic interference,keep signal linearity and measuring precision for long-distance wiring.

Installation:Connect Lemo plug between probe and extension cable,another end connect to CON021 preamplifier. Fix cable along bearing housing,avoid sharp bending and extrusion.

Interface:

‑Lemo male coaxial connector

‑Lemo female coaxial connector

‑Armored shielded coaxial inner wire

Circuit feature:Low loss high frequency coaxial core,high temperature resistant PTFE insulation,continuous metal armor shielding,anti vibration,anti oil and anti high temperature.

Feature:EPRO original armored extension cable for PR6423 eddy current probe. The total cable length(probe integrated cable + extension cable) must match calibrated measuring chain. Common faults:armor crack,inner coaxial wire breakage,connector pin corrosion. Confirm total cable length before replacement.

Diagnostic:Cable fault leads to gap signal drift,signal loss,TSI channel alarm,losing vibration and displacement monitoring.

Built‑in function

PR6423 extension cable extends wiring distance of eddy current probe,widely used for power plant TSI system spare replacement.

Product Brief

PR6423 extension cable belongs to EPRO eddy current sensor spare parts family,armored coaxial extension cable for PR6423 probe. The total cable length must be consistent with the original calibrated set,otherwise sensitivity will shift. Verify total length and matched CON021 preamplifier before ordering. Check insulation and coaxial continuity during commissioning. Widely applied for steam turbine,compressor and generator condition monitoring. ESD anti‑static protection shall be followed during installation.
