Frequently asked questions (FAQ)

• What is the linear range of this probe?
  The linear range spans 0.25 mm to 1.75 mm (1.5 mm total). This covers standard vibration and displacement measurements.
• Can I use this 0.5m probe with a longer extension cable?
  Yes, the 3300 NSv system supports extension cables up to 305 meters. Total resistance includes probe plus extension, so verify compatibility.
• What does FluidLoc cable offer?
  FluidLoc resists oil and moisture ingress, protecting the coaxial conductor. It extends cable life in lubricated machinery environments.
• Is the probe tip field‑replaceable?
  No, the tip is permanently sealed. The PPS material offers excellent wear resistance. Replace the entire probe if damaged.
• What is the return policy?
  We accept returns within 30 days for unused items in original packaging. Return shipping is the buyer's responsibility.
• How does temperature affect scale factor?
  The scale factor tolerance (±12.5%/-20%) includes temperature effects over the -52°C to +177°C range. Calibration compensates for most applications.
• What is the minimum target size for accurate measurement?
  Bently Nevada recommends a target diameter of at least 13 mm. The absolute minimum is 8.9 mm for reduced linear range.
