Frequently asked questions

• Q: Can I use this probe with a 9 m extension cable? Yes, the system works with 9 m cables, but ISF accuracy becomes ±6.5% and DSL < ±0.038 mm.
• Q: Does the probe withstand high pressure? The Viton O-ring seals differential pressure. Contact our custom department if you need tested pressure seals.
• Q: What is the maximum field wiring distance? You can run up to 305 m (1000 feet) between the Proximitor and monitor. Check frequency response graphs for signal roll-off at longer lengths.
• Q: Is the probe tip replaceable? No, the tip is permanently molded using TipLoc technology. The entire probe is a single assembly.
