FAQ
-
What is the recommended target material for optimal linearity?
The probe is factory-calibrated for AISI 4140 steel; other ferromagnetic materials may require calibration adjustments. -
What is the maximum cable length extension supported?
The standard system supports up to 9 meters when used with matching extension cables and a compatible proximitor. -
Can the probe operate in hazardous areas?
Yes, it meets ATEX and CE requirements for Zone 1 hazardous environments when installed with approved accessories. -
How does temperature variation affect measurement accuracy?
The probe is temperature-compensated to minimize drift across its specified operating range. -
What is the typical output from the proximitor for this probe?
The standard output is 200 mV per mil (7.87 V/mm) with ±5 % tolerance. -
Can the probe detect both vibration and shaft position?
Yes, it provides both dynamic vibration and static shaft position signals. -
What is the minimum bend radius for the cable during installation?
The recommended minimum bend radius is 25 mm to prevent cable damage. -
Does the probe require regular recalibration?
Recalibration is generally only necessary after component replacement or major system changes. -
