Epro PR6424/010-040+CON021 16mm Eddy Current Sensor

The Epro PR6424/010-040 + CON021 is a non-contact eddy current displacement sensor system used primarily in vibration and axial position measurement of rotating machinery. Designed for demanding industrial applications, this sensor has a probe diameter of 16mm and is paired with the CON021 signal converter, offering reliable signal transmission to monitoring systems like the Epro MMS6000 or BN 9200 series.

The PR6424 series is renowned for its robust construction, high linearity, and compatibility with high-speed turbo machinery. The system operates on the principle of electromagnetic induction, detecting the distance between the sensor tip and a conductive target surface. It provides static and dynamic displacement data, critical for predictive maintenance and machinery protection systems.

This specific configuration, PR6424/010-040, offers a 40mm cable length and is optimized for environments where compact mounting, electrical insulation, and vibration resistance are crucial.

Frequently Asked Questions (FAQ)

1. Q: What does the “010-040” in the model number represent?

   A: It refers to the specific probe version (010) and a 4.0-meter cable length (040) between the probe and the converter.

2. Q: Can the sensor be used in high-temperature zones?

   A: Yes, the sensor head operates up to +180°C, making it ideal for high-temperature machinery like turbines and compressors.

3. Q: Is the PR6424/010-040 compatible with Bently Nevada systems?

   A: While it is optimized for Epro and BN 9200 systems, it can be adapted for use in certain Bently systems with signal conditioners.

4. Q: Can this sensor measure both static and dynamic displacement?

   A: Yes, it provides both static position (e.g., axial displacement) and dynamic vibration measurement.

5. Q: Does the CON021 converter require external power?

   A: No, it is typically powered by the monitoring system (e.g., MMS6000) and does not need a separate power supply.

6. Q: Is recalibration required after installation?

   A: Recalibration is generally not required unless the probe-target gap or target material changes.

7. Q: What material should the target surface be for accurate calibration?

   A: The system is calibrated for DIN 1.7225 (AISI 4140); using other materials may affect linearity unless recalibrated.

8. Q: How do I verify if the sensor is operating correctly?

   A: Check output signal using an oscilloscope or connect to a compatible vibration monitor with diagnostics.

9. Q: Can the cable be extended beyond 4 meters?

   A: Not recommended unless matched with a properly calibrated CON041/021 converter designed for longer distances.

10. Q: Is it safe to use in hazardous zones?

    A: Yes, explosion-proof (Ex) versions of the PR6424 series are available for ATEX Zone 1/2 applications.
