FAQ
-
What target material is recommended for accurate calibration?
The probe is factory-calibrated for AISI 4140 steel; other ferromagnetic materials may require system recalibration. -
What is the maximum permissible extension cable length?
The system supports extensions up to 9 meters when paired with a compatible Bently Nevada proximitor. -
Is the probe certified for hazardous area installation?
Yes, it complies with ATEX and CE standards for Zone 1 hazardous locations when used with approved accessories. -
How does operating temperature affect signal accuracy?
The probe is temperature-compensated to minimize measurement drift across the full operating range. -
What is the output sensitivity when paired with a standard proximitor?
The output is typically 200 mV per mil (7.87 V/mm) with ±5% tolerance. -
Can it measure both dynamic vibration and static shaft position?
Yes, the probe provides simultaneous vibration and position data. -
What is the recommended cable bend radius during installation?
A minimum bend radius / 25 mm is recommended to maintain cable integrity. -
Does the system require regular calibration checks?
Calibration is generally only required after component replacement or significant configuration changes. -
Is the probe shielded against electromagnetic interference (EMI)?
Yes, its coaxial cable design provides excellent EMI resistance. -
Can this probe operate with older Bently Nevada monitoring systems?
