Frequently Asked Questions (FAQ)
-
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. -
Can it be used in high-temperature environments?
Yes, the probe supports temperatures up to 180°C and the cable up to 125°C. -
Is it compatible with the CON011 module?
Yes, it is fully compatible with CON011 and also works with CON021 modules. -
What is the thread type for mounting?
Standard M10x1 threading is used. Custom threads are also available upon request. -
Can I cut or shorten the 10-meter cable?
No. The cable is factory-calibrated and permanently attached to ensure signal integrity. -
What’s the typical output signal format?
Analog voltage output, typically 7.87 mV/μm (depending on calibration). -
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. -
Can this sensor detect both radial and axial displacement?
Yes, depending on how you position the probe relative to the shaft. -
Is the sensor explosion-proof?
