FAQ
-
What target material is recommended for best linearity?
The probe is factory-calibrated for AISI 4140 steel; other ferromagnetic materials may require recalibration. -
What is the maximum extension cable length supported?
Up to 9 meters when paired with an appropriate Bently Nevada proximitor and matching extension cables. -
Can the probe be installed in hazardous areas?
Yes, it meets ATEX and CE Zone 1 requirements when installed with certified accessories. -
How is accuracy affected by temperature variation?
Built-in temperature compensation minimizes measurement drift across the specified operating range. -
What is the standard output sensitivity with a proximitor?
Typically 200 mV per mil (7.87 V/mm) with ±5 % tolerance. -
Does the probe measure both vibration and static shaft position?
Yes, it provides dynamic vibration and static displacement signals simultaneously. -
What cable bend radius is recommended during installation?
A minimum bend radius / 25 mm is recommended to avoid cable damage. -
Is regular calibration required?
Calibration is generally only necessary after system reconfiguration or component replacement. -
Is the probe protected against electromagnetic interference (EMI)?
Yes, the coaxial cable and internal shielding provide strong EMI resistance. -
Can it interface with older Bently Nevada monitoring systems?
