Frequently Asked Questions (FAQ)

1. What is the main function of the PR6423/13R-010 sensor?

   It measures shaft displacement and vibration using the eddy current principle in a non-contact manner.

2. Can it be used in high-temperature environments?

   Yes, the probe supports temperatures up to 180°C and the cable up to 125°C.

3. Is it compatible with the CON011 module?

   Yes, it is fully compatible with CON011 and also works with CON021 modules.

4. What is the thread type for mounting?

   Standard M10x1 threading is used. Custom threads are also available upon request.

5. Can I cut or shorten the 10-meter cable?

   No. The cable is factory-calibrated and permanently attached to ensure signal integrity.

6. What’s the typical output signal format?

   Analog voltage output, typically 7.87 mV/μm (depending on calibration).

7. Does it require calibration in the field?

   Factory-calibrated units are ready to use. Field calibration is typically not necessary unless environmental changes demand it.

8. Can this sensor detect both radial and axial displacement?

   Yes, depending on how you position the probe relative to the shaft.

9. Is the sensor explosion-proof?

   ATEX or other certifications are available upon request for use in hazardous areas.

10. What’s the lifespan of this sensor?

    It can last over 10 years in continuous operation if correctly installed and protected.
