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