Application-Specific FAQ
Q: Is the 330104-04-18-50-02-00 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. This probe is part of the 3300 XL system and is fully compatible with the 3500 Series rack when used with the appropriate 3300 XL Proximitor driver module.
Q: What is the difference between the 330104 and 330105 series?
A: The 330104 uses an 8mm probe tip and is the standard API 670 configuration. The 330105 is a 5mm probe variant for tighter installation geometries. Verify your existing probe holder bore before substituting.
Q: Can this transducer be used on non-ferromagnetic shafts (e.g., titanium or Inconel)?
A: No. The 3300 XL eddy-current system requires a ferromagnetic target material (AISI 4140 or equivalent). For non-ferromagnetic targets, a different transducer technology is required — contact us for guidance.
Q: Do you supply calibration certificates?
A: Yes, calibration verification reports are available on request. Please specify this requirement at the time of order.
Q: What is the lead time for urgent plant shutdowns?
A: We maintain stock of common Bently Nevada proximity transducer assemblies. Contact us directly for expedited quotation and same-day shipping options.
