Frequently Asked Questions
- Q: What is the unthreaded length used for?A: The 0.5″ unthreaded section passes through thick mounting pads or insulation without engaging threads, allowing proper positioning.
- Q: Can I use this probe with 3300 XL extension cables?A: Yes – mate with Bently Nevada 3300 series extension cables that have ClickLoc connectors (female).
- Q: What does “CN” approval cover?A: Country specific approvals for China, including hazardous area certifications accepted by Chinese authorities.
- Q: How deep can this probe reach?A: 6.3″ case length + 0.5″ unthreaded = 6.8″ total from mounting surface to tip (adjust gap as needed).
- Q: Is the 6.3″ case rigid or flexible?A: Rigid stainless steel – maintains precise tip position in high vibration.
- Q: What’s the minimum gap I can measure?A: Typically 0.25mm to 2.25mm linear range. Set static gap around 1.27mm (50 mils).
- Q: Can this probe withstand steam turbine temperatures?A: Yes – rated to 177°C continuous. For higher, check T1 rating (232°C) in temperature schedule.
- Q: How does magnetic field affect readings?A: Very low – probe and cable contribute <0.005 mV pp/Gauss at typical gaps, safe for generators.
