Application-Specific FAQ
Q: Is the 330171-00-12-10-02-CN compatible with the 3500 Series monitor rack?
A: Yes. The 3300 XL Proximitor output is electrically compatible with 3500 Series monitor inputs. Verify gap voltage and scale factor settings in the monitor configuration.
Q: What shaft material is required for accurate readings?
A: The standard calibration targets AISI 4140 steel. For stainless steel, Inconel, or other alloys, a material correction factor must be applied — contact Bently Nevada or Konmask for a recalibration certificate.
Q: Can this transducer be used in a SIL 2 safety loop?
A: The 3300 XL system is SIL-capable when integrated with a certified safety monitor module (e.g., 3500/42). A full SIL assessment including PFD calculations should be performed by a qualified functional safety engineer.
Q: What does the “CN” suffix mean?
A: CN denotes the China-market configuration, which includes Chinese-language documentation, compliance paperwork aligned with GB standards, and may include specific connector or cable variants suited to local installation practices.
Q: What is the typical lead time?
A: Ex-stock units ship within 3–5 business days. For new-manufacture orders, lead time is typically 8–14 weeks. Contact us to check current availability.
