Cable length:3m

Measurement principle:Non-contact eddy current

Static measuring range:±2mm

Sensitivity:4V/mm,accuracy ±1.5%FS

Frequency response:0~10kHz

Probe thread:M18×1.5

Probe operating temperature:-35~+180℃

Probe protection:IP65

Weight:0.2kg

Dimensions:Φ16mm ×65mm(probe head)

Certification:CE,API670 compliant

System compatibility:Matches EPRO MMS6000 TSI monitoring system,works with CON021 preamplifier.Suitable for large steam turbine,generator,compressor shaft radial vibration and axial displacement measurement,shaft diameter ≥80mm.

Function:Non-contact real-time detection of rotating shaft vibration and axial displacement.Convert air gap change between probe and metal shaft into weak coil signal,transmit to CON021 preamplifier for signal conditioning,deliver conditioned signal to MMS series monitoring module for alarm and protection interlock.

Installation:Thread mounting on bearing housing,adjust working air gap to nominal 2.7mm.Lemo coaxial connector connect probe to CON021 preamplifier.

Interface:

‑Stainless steel M18×1.5 threaded probe body

‑3m armored PTFE integrated cable

‑Lemo coaxial connector for preamplifier connection

Circuit feature:High stability coil design,high temperature armored cable,strong anti-interference,adapt to harsh oil and high temperature bearing housing environment.

Feature:EPRO classic 16mm large diameter eddy current probe,3m cable version,used for large rotating shaft measurement. Larger probe tip requires bigger metal target surface. Common faults:cable breakage,coil aging,Lemo connector pin corrosion. Confirm full model and matched preamplifier before replacement.

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

Built‑in function

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

Product Brief

PR6424/003-030 belongs to EPRO eddy current sensor spare parts family,16mm probe with 3m armored cable.It must be used with CON021 preamplifier. Verify preamplifier and TSI card compatibility before ordering. Check cable insulation and probe coil output function during commissioning.Widely applied for large steam turbine,compressor and generator condition monitoring.ESD anti‑static protection shall be followed during installation.
