Application-Specific FAQ
Q: Is the 330103-01-07-05-02-00 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. When paired with the correct 3300 XL Proximitor driver and 330130/330180 extension cable, the probe integrates directly with 3500/40M and 3500/42M monitor modules.
Q: What target material is required for accurate measurement?
A: The probe is calibrated for AISI 4140 steel. For other shaft materials (stainless, titanium, Inconel), a material correction factor must be applied — consult Bently Nevada application note 141-108.
Q: Can this probe be used in a hazardous area (Zone 1 / Division 1)?
A: Hazardous area suitability depends on the complete probe-driver assembly certification. Verify the ATEX/FM suffix codes on both the probe and Proximitor before installation in classified areas.
Q: What is the recommended gap voltage at installation?
A: Nominal gap voltage is –10.0 VDC (corresponding to approximately 1.0 mm gap) when powered by a –24 VDC Proximitor. Adjust per OEM commissioning procedure.
Q: Do you offer calibration or repair services?
A: We supply new and surplus units. For calibration or repair, contact your regional Bently Nevada / Baker Hughes service center. We can assist with sourcing replacement units during repair turnaround.
