Epro PR6424/012-000 16mm Eddy Current Sensor

The Epro PR6424/012-000 is a robust, non-contact eddy current proximity sensor designed to measure shaft displacement, vibration, and axial position in industrial rotating machinery. Developed by EPRO (now under Emerson), this model features a 16 mm diameter probe and is intended for use in conjunction with the CON011 converter, making it a core component of Epro’s machinery condition monitoring and protection systems.

Engineered to perform under extreme conditions, the PR6424/012-000 offers exceptional stability, linear output, and resistance to temperature fluctuations, oil ingress, and electrical noise. The sensor plays a vital role in machinery protection systems compliant with API 670, especially in turbomachinery and heavy-duty rotating equipment. This particular model is factory-calibrated and optimized for applications requiring longer sensing distances and high measurement precision.

FAQ

1. Q: What is the difference between PR6424/012-000 and PR6424/011-100?

   A: Both have 16 mm probes, but differ in cable configuration and factory calibration for cable length.

2. Q: Does this sensor include a cable?

   A: No, PR6424/012-000 is supplied without an integral cable; a separate cable is connected to the CON011 converter.

3. Q: Can I use this sensor with a third-party monitoring system?

   A: It is optimized for use with EPRO CON011 and MMS systems. Integration with third-party systems may require signal adaptation.

4. Q: What is the maximum temperature it can handle?

   A: Up to 180°C, depending on accessories such as high-temperature cables and mounting configurations.

5. Q: Is this sensor compliant with API 670?

   A: Yes, it fully meets API 670 requirements for critical rotating machinery monitoring.

6. Q: What types of materials can this sensor measure?

   A: It is designed to measure displacement from ferromagnetic materials like steel (e.g., AISI 4140).

7. Q: Is the sensor tip oil-resistant?

   A: Yes, the sensor is sealed and rated IP65 at the tip, making it resistant to oil and moisture when properly installed.

8. Q: What happens if I exceed the sensing range?

   A: Exceeding the range can lead to inaccurate readings or signal clipping. Always install within the specified gap.

9. Q: Can the sensor be used in underwater applications?

   A: No, it is not rated for continuous submersion. Use with sealed housings or enclosures for such environments.

10. Q: Is recalibration needed after installation?

    A: No, the sensor is factory-calibrated. However, system calibration is recommended if components are replaced or relocated.
