Application-Specific FAQ
Q: Is the 330901-04-35-50-01-00 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. The 3300 XL NSv driver outputs a standard –24 VDC-based signal fully compatible with 3500/40M and 3500/42M Proximitor I/O modules.
Q: What is the difference between the NSv and standard 3300 XL variants?
A: NSv (Non-Standard voltage) models operate from a –24 VDC supply rather than the standard –18 VDC, providing extended linear range and improved noise immunity in high-interference environments.
Q: Can this transducer be used on non-ferrous shafts?
A: The standard calibration targets AISI 4140 steel. For stainless steel, titanium, or Inconel shafts, a material correction factor must be applied. Contact us for application-specific calibration data.
Q: What is the maximum shaft speed this system can monitor?
A: The 3300 XL NSv system has a frequency response of DC to 10,000 Hz, supporting shaft speeds up to 600,000 RPM in theory; practical limits are set by the monitoring system and application.
Q: Do you provide installation and commissioning support?
A: We provide technical documentation, wiring diagrams, and remote commissioning guidance. On-site support can be arranged through our partner network.
