FAQ
-
Which target material ensures optimal calibration accuracy?
Factory calibration is done for AISI 4140 steel; other ferromagnetic materials may require recalibration. -
What is the maximum extension supported beyond the 5-meter cable?
Extensions up to 9 meters are supported with a compatible proximitor and extension cables. -
Can this probe be used in hazardous environments?
Yes, it meets ATEX and CE Zone 1 requirements when installed with certified accessories. -
How does temperature variation affect measurement accuracy?
Integrated temperature compensation minimizes drift across the full operating range. -
What is the typical output sensitivity when connected to a proximitor?
Standard output is 200 mV per mil (7.87 V/mm) with ±5% tolerance. -
Does this probe measure both vibration and static shaft position?
Yes, it provides simultaneous dynamic and static measurement signals. -
What is the recommended minimum bend radius for installation?
A minimum bend radius / 25 mm is recommended to protect cable integrity. -
Is recalibration required under normal operation?
Recalibration is generally only necessary after system reconfiguration or replacement / components. -
Is the probe resistant to electromagnetic interference (EMI)?
Yes, the coaxial cable design and internal shielding provide excellent EMI resistance. -
Is it compatible with older Bently Nevada monitoring systems?
Yes, when used with the correct proximitor and following proper calibration procedures.
