Epro PR6424/002-130 16mm Eddy Current Sensor

Product Introduction

The Epro PR6424/002-130 Eddy Current Sensor is a high-performance, non-contact measurement device designed for precision monitoring of shaft vibration, displacement, and position in rotating machinery. With a 16mm probe diameter, it is part of the widely trusted PR6424 series, which is known for its reliability in harsh industrial environments such as turbines, compressors, pumps, and gearboxes. This sensor integrates seamlessly into condition monitoring and machine protection systems, ensuring continuous operation and early detection of faults.

The sensor is typically used in combination with CON0xx series extension cables and drivers, forming a complete eddy current measurement system. Its rugged design, high linearity, and immunity to oil, dirt, and high temperatures make it a preferred solution for predictive maintenance strategies in critical industries.

• Proven reliability – part of the globally recognized PR6424 series used in critical industries.

FAQ

1. How does the PR6424/002-130 measure shaft vibration?
   It uses the principle of eddy currents, where changes in distance between the probe tip and the metallic shaft surface produce variations in impedance, which are then converted into displacement or vibration signals.

2. Can this sensor be connected directly to monitoring systems?
   No, it requires a driver module (e.g., CON021 or CON041) that conditions the signal before being sent to monitoring or control systems.

3. What is the maximum cable length that can be used with this sensor?
   Typically up to 9 meters when paired with the appropriate extension cable and driver, ensuring signal integrity.

4. Does shaft surface condition affect sensor accuracy?
   Yes, the shaft must have a smooth, conductive surface. Roughness, coatings, or non-metallic materials can reduce accuracy.

5. Can the sensor be used in high-pressure environments?
   Yes, the housing is pressure-resistant up to 10 bar, making it suitable for sealed machinery housings.

6. How is temperature compensation achieved in this sensor?
   The sensor and driver are designed to compensate for temperature variations, maintaining stable output across the specified range.

7. What type of signals does the driver output when paired with this sensor?
   The driver typically provides a voltage signal proportional to displacement, often in the range of 0–20 V.

8. Is shielding required for installation?
   The sensor uses a coaxial cable that provides inherent shielding, but proper grounding practices must be followed to avoid noise interference.

9. Can multiple sensors be installed on the same shaft?
   Yes, typically two sensors are installed orthogonally for X-Y vibration measurement, enabling orbit analysis.

10. What is the frequency response range of this sensor?
    Up to 10 kHz (–3 dB), suitable for monitoring high-speed machinery.
