Description

PR6424/010-130 + CON011 EPRO 16mm Eddy‑Current Probe M18 Thread 8‑Meter Armored Cable, High‑Bandwidth Non‑Contact Shaft Displacement Sensor for Large‑Diameter Shaft Radial Vibration, Axial Thrust & Eccentricity Monitoring

 

Product Application

PR6424/010‑130 belongs to EPRO PR6424 series 16mm large tip eddy‑current probe, /010 means armored integrated cable, -130 represents total 8m armored cable with factory LEMO plug. Matched with CON011 wideband preamplifier to constitute complete measurement chain. Specially designed for large‑diameter rotating shafts (minimum target shaft ≥80mm). Widely deployed on steam turbines, hydro turbines, large centrifugal compressors, blowers and heavy‑duty pumps in petrochemical, oil & gas and thermal power plants. Typical measuring parameters: X/Y orthogonal radial vibration, axial thrust position, shaft eccentricity and rotor runout. Gap voltage signal from CON011 is sent to Emerson CSI6500 TSI monitoring modules for machinery alarm and trip protection; high‑frequency vibration waveform data uploaded to AMS predictive maintenance platform. The full set meets API 670 turbomachinery protection specification.

Product Features

✅ 16mm Large Ceramic Tip with M18×1.5 Thread Big sensing coil, uniform electromagnetic field, excellent signal stability for large‑diameter heavy rotating shafts; M18 thread fits dedicated heavy‑duty probe bracket.

✅ 4 V/mm High Sensitivity & ±2mm Linear Range Higher sensitivity than conventional 2 V/mm probes, small shaft displacement can get larger voltage output, improves measurement resolution.

✅ 8 Meter Pre‑assembled Armored Cable + LEMO Plug 8m long armored cable variant, suitable for long‑distance wiring from bearing housing to remote junction box, no intermediate extension cable required.

✅ Much wider frequency bandwidth than CON021, can capture high‑frequency vibration components of high‑speed turbomachinery.

✅ Each probe‑preamplifier pair is calibrated before delivery to guarantee 4 V/mm sensitivity accuracy.

✅ High Temperature & Oil Resistant Probe Assembly Probe head can continuously withstand 180℃; armored PTFE cable resists lubricating oil corrosion inside bearing housing.

✅ Hazardous Zone Certified Suitable for Zone 2 / Class I Div 2 explosive gas area installation in petrochemical plants.

 

Installation Guidelines

  1. Install rigid heavy‑duty probe bracket on bearing housing, confirm bracket thread matches M18×1.5 probe sleeve, avoid bracket resonance at unit operating speed.
  2. Screw PR6424/010‑130 probe into bracket, adjust static gap between probe tip and shaft target surface to around 2.7 mm, lock the lock nut.
  3. Route 8m armored cable, avoid sharp bending and heavy extrusion; fasten LEMO plug tightly to preamplifier.
  4. Mount preamplifier in junction box away from high‑temperature radiation.
  5. Connect signal output to front BNC port of CSI6500 TSI module with dedicated coaxial cable.
  6. Power on CSI6500 rack, read gap voltage value on AMS workstation and confirm probe works within linear interval.
  7. Perform dynamic test during turbine / compressor startup.
  8. Verify vibration value, displacement reading and alarm trip logic before putting machinery protection online.

 

Maintenance Instructions

Daily Maintenance Monitor real‑time gap voltage and measurement value in AMS software. Check bracket looseness, armored cable oil erosion and LEMO connector oil contamination.

Periodic Maintenance Every 6–12 months: Inspect probe tip scratch and oil sludge contamination. Calibrate the whole probe‑‑TSI measurement loop with dynamic calibrator. Back up CSI6500 project configuration.

Fault Maintenance

  • Gap voltage out of linear range: Check bracket loosening, shaft runout or probe collision.
  • No measurement signal: Inspect LEMO connector locking status, cable breakage and power supply.
  • Signal drift: Clean oil sludge on probe tip or replace probe assembly.
  • ESD protection required during replacement; do not disassemble probe head and housing.

Long‑Term Operation Tips Respect cable minimum bending radius. Prevent lubricating oil long‑term immersion on LEMO connector. Regularly check bracket resonance under working speed.
