Application-Specific FAQ
Q: Is the 330905-08-13-10-12-CN compatible with the 3500 monitoring rack?
A: Yes. When paired with the correct 3300 XL Proximitor driver and matched extension cable, this probe integrates directly with the Bently Nevada 3500 series rack.
Q: What is the difference between the CN and standard (non-CN) variants?
A: The CN suffix denotes a connector configuration optimized for Chinese domestic installation standards. Electrically and mechanically, performance specifications are identical to the international variant.
Q: Can this probe measure axial position as well as radial vibration?
A: Yes. With appropriate mounting orientation and a compatible thrust monitor module (e.g. 3500/46M), the same probe type can measure axial shaft position.
Q: What target material is required for accurate readings?
A: AISI 4140 steel is the standard reference target. Other ferromagnetic materials require a target material correction factor — consult the Bently Nevada calibration guide.
Q: Do you provide calibration certificates?
A: Yes. Calibration documentation is available upon request for all units shipped from Konmask.com.
Q: What is the lead time for this part?
A: Typical lead time is 3–7 business days for in-stock units. Contact us for current availability.
