Application-Specific FAQ
Q: Is the 330910-10-22-10-01-CN compatible with the Bently Nevada 3500/42M Vibration Monitor?
A: Yes. The NSv probe is factory-calibrated for use with 3500-series drivers. Verify the driver gap voltage range (−10 V to −18 V) matches your installation gap.
Q: What is the difference between the -01-CN and -01-00 suffix?
A: The -CN suffix denotes a Chinese-market connector variant with a localized termination standard. Electrically and mechanically, the probe is identical to the -01-00 international variant.
Q: Can this probe be used on non-ferrous targets such as titanium or aluminum?
A: The standard NSv probe is calibrated for steel targets. Non-ferrous target use requires a target-material correction factor or a custom-calibrated probe. Contact us for details.
Q: What is the recommended installation gap for this probe?
A: The nominal installation gap is 50 mil (1.27 mm), corresponding to the midpoint of the linear range. Refer to Bently Nevada Installation Manual 141536-01 for torque specifications.
Q: Do you offer expedited shipping to mainland China?
A: Yes. We ship via DHL Express and SF International with typical transit times of 2–4 business days to major Chinese cities.
