Application-Specific FAQ
Q: Is the 330103-00-05-50-02-CN compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. The 3300 XL proximity system is fully compatible with 3500 series Proximitor I/O modules when used with the appropriate driver (330180 series). Verify the driver part number matches your rack slot configuration.
Q: What is the difference between the -02-CN and -00-CN suffix?
A: The -02 suffix denotes a 2 m extension cable included in the system kit; -CN indicates the China-market configuration. Sensing performance and scale factor are identical to the global variant.
Q: Can this probe measure axial position as well as radial vibration?
A: Yes. The 330103 series supports both radial vibration and thrust/axial position measurement. Ensure the monitoring channel is configured for the correct measurement mode in the 3500 rack software.
Q: What target material is assumed for factory calibration?
A: Factory calibration is performed against AISI 4140 steel. For non-standard target materials (e.g., titanium, Inconel, stainless steel), a field recalibration or material correction factor must be applied per API 670 Annex D.
Q: Is this unit available with ATEX certification for Zone 1 hazardous areas?
A: The 3300 XL series includes ATEX/IECEx-certified variants. Confirm the specific approval code on the probe label before installation in classified areas. Contact Konmask for certified stock availability.
