Application-Specific FAQ
Q: Is the 330101-00-28-10-12-CN compatible with the Bently Nevada 3500 rack?
A: Yes. It is fully compatible with the 3500/42M and 3500/40M Proximitor® Monitor cards when paired with the correct NSv Proximitor® driver.
Q: What is the difference between the -10-12-CN and -10-02-CN suffix?
A: The third numeric group (12) denotes the 12 mm linear measurement range. The -02 suffix indicates a 2 mm range, suited for tighter gap applications. The -CN suffix designates the China-market configuration.
Q: Can this probe be used on stainless steel shafts?
A: Standard calibration targets AISI 4140 steel. For 316 SS or other non-ferrous targets, a target-material correction factor or field recalibration is required. Contact our engineering team for guidance.
Q: What is the maximum shaft speed this transducer can monitor?
A: The 10 kHz frequency response supports shaft speeds up to approximately 600,000 RPM for single-event detection, well beyond the 3,600–25,000 RPM range of most industrial turbomachinery.
Q: Do you provide calibration certificates?
A: Yes. Factory calibration documentation is included with every unit. NIST-traceable recalibration services are available on request.
