Epro PR6424/006-030+CON021 16mm Eddy Current Sensor

Product Introduction

The Epro PR6424/006‑030 paired with the CON021 converter constitutes a highly accurate, non‑contact eddy current sensor system designed for shaft displacement and vibration measurement in rotational machinery. Featuring a 16 mm probe tip diameter, this model delivers excellent sensitivity and linearity, suitable for large‑shaft applications in turbines, compressors, pumps and fans.

The CON021 module amplifies and conditions the raw sensor signal into a standard analog voltage output compatible with monitoring platforms such as VM600, MMS6000, CSI 6500, and similar systems. Engineered to withstand harsh industrial environments, this sensor system is widely used within energy, petrochemical and heavy‑equipment industries for condition monitoring and machine protection.

Product Specifications

Product Applications

• Turbomachinery Monitoring
  Tracks radial and axial shaft movement in steam, gas and hydro turbines for early detection of imbalance or bearing wear.

• Compressor Diagnostics
  Measures shaft vibration and eccentricity in centrifugal and reciprocating compressors.

• Pump and Fan Monitoring
  Used for real‑time displacement tracking in high‑speed industrial pumps and fans.

• Generator Sets and Motor Monitoring
  Integrates into condition monitoring systems to prevent mechanical failures in rotating power equipment.

• Axial Thrust Measurement
  Detects axial displacement in thrust bearings of compressors and turbines.

• Machine Protection Systems
  Enables automatic alarm or shutdown activation in case of abnormal shaft movement.

Product Advantages

• High Sensitivity and Accuracy
  With sensitivity around 4 V/mm and linearity within ±1.5 %, it delivers reliable displacement measurements.

• Large Tip for Bigger Shafts
  The 16 mm probe tip suits large‑diameter shafts (≥80 mm), offering improved target coverage.

• Wide Operating Temperature Range
  Stable performance from −35 °C up to +180 °C supports use in extreme thermal conditions.

• Excellent Vibration and Shock Tolerance
  Engineered for critical rotating machinery with vibration and shock resilience up to 100 m/s² and 500 m/s².

• Non‑Contact Measurement
  Reduces mechanical wear, improves longevity and minimises maintenance needs.

• Robust Industrial Grade Design
  Stainless steel construction with IP65 protection resists corrosion and environmental stress.

• Flexible Integration
  Paired with CON021, offers easy integration into standard monitoring platforms via analog output.

• Configurable and Field‑Customisable
  Available with varied thread options, custom sensor lengths, and industry‑standard connectors.

FAQ

1. What is the nominal sensitivity and linearity of this sensor system?
   Approximately 4 V/mm with linearity within ±1.5 %.

2. What is the static measurement range supported?
   ±2.0 mm static range is supported; dynamic monitoring typically up to 1000 µm.

3. What frequency range does the sensor handle reliably?
   Up to approximately 8 kHz, sufficient for typical shaft vibration monitoring.

4. Which thread type is standard for mounting?
   M18×1.5 or ¾‑16 UNF depending on application and shaft size.

5. Is this sensor suitable for high‑speed rotational environments?
   Yes—designed for continuous vibration up to 100 m/s² and shock up to 500 m/s².

6. What output formats are supported via the CON021 converter?
   Common outputs include 0–10 V DC or 4–20 mA analog signals, depending on wiring and calibration.

7. How is the sensor calibrated to the target surface?
   Calibration must be carried out on a ferromagnetic steel target (e.g. DIN 1.7225) with specified gap and converter setup.

8. How is electromagnetic interference handled?
   The sensor and converter cable are shielded; proper grounding practice further ensures EMI resilience.

9. Can this probe measure both radial and axial displacement?
   Yes, orientation of mounting determines whether radial or axial movement is measured.

10. What is the recommended shaft diameter for safe operation?
    Minimum shaft diameter is approximately 80 mm to ensure adequate target sensing area.
