Frequently Asked Questions (FAQ)

• What is the standard cable length?
  • This model has 1.0 metre total length.
  • Also available in 5m and 9m by special order.
• Can I extend the probe cable?
  • Yes, use Bently Nevada triaxial extension cables.
  • Keep total system length under 305 meters.
• How do I check if my probe is broken?
  • Measure center to outer conductor resistance.
  • It should read 5.9 ± 0.5 ohms at 25°C.
  • If open or short, replace the probe.
• What happens if I exceed torque?
  • Case thread may strip or crack.
  • Always stay below 63.3 N•m maximum.
• Does this probe work in high humidity?
  • Yes, 100% condensing humidity tested.
  • But do not submerge connectors.
• Experience: probe reads noisy signal. Why?
  • Check grounding of the driver and monitor.
  • Verify cable bend radius is not too tight.
  • Look for nearby 60 Hz magnetic fields above 300 Gauss.
• 选购指导 (Selection guide)
  • Choose unthreaded length 000 for standard mounting.
  • Pick overall case length 050 (50mm) for most turbine bearings.
  • Select 1.0m total length (10) for short cable runs.
  • Use ClickLoc connector (02) for easy maintenance.
  • If you need ATEX/IECEx approval, choose option other than 00.
  • For large shafts >152mm, this probe works best.
  • For small shafts (<152mm), consider 8mm probe.
