👨‍🔬 Manager’s insight – 8 mm advantage

We have seen 5 mm Proximity Probes work in tight spots, but the 8 mm version offers unmatched ruggedness. The thicker PPS tip and 330 N pull strength reduce downtime in high‑vibration machines. For new installations, choose the 1 m one‑piece assembly – simpler and more reliable. If oil leaks are a concern, add FluidLoc. This 330191 build is our top pick for steam turbine radial vibration.

📎 5 mm vs 8 mm – selection tree

• ➤ 3300 5 mm Proximity Probes (compact) – for confined areas
• ➤ This 8 mm probe (330191-00-26-10-00) – maximum durability
• ➤ Alternative part numbers
  • 330191-40-75-50-CN – different case length/options
  • 330191-40-75-90-05 – with armor & extended temp cable
• Selection guide: For temperatures above 177 °C, order PFA cable. For high pressure, verify thread engagement ≤0.563 in.

❓ Field FAQ

• Q: Can I pair this 8 mm probe with an older 5 mm extension?A: No – always use 3300 XL 8 mm extension cables. The 1 m system avoids extension entirely.
• Q: What does total length option “10” actually mean for installation?A: “10” = 1.0 meter one‑piece probe + cable. No extra connector, better signal integrity.
• Q: FluidLoc – do I need it for dry gas seals?A: Only for oil‑lubricated machines. If you have oil mist or wet sumps, choose FluidLoc.
• Q: Is this probe compatible with 3300/20 monitor?A: Yes – all 3300 XL monitors support 8 mm probes. Verify power supply range.
• Q: How do I avoid damaging the tip during assembly?A: Use the wrench flats on case – never pull the cable. TipLoc already prevents internal looseness.
• Q: Which agency approval suffix for Zone 1?A: -00 is not certified. You need -05 (ATEX) or -CN with barriers. Consult factory.
