Frequently Asked Questions (FAQ)

• What is the total length of this probe?
  It is 5.0 meters (16.4 feet). This length works only with 5-meter Proximitor sensors.
• Can I use this probe with an extension cable?
  Yes. Use 330190-085-00-CN or 330190-085-00-05 for longer runs. Ensure the total cable length matches the Proximitor sensor requirements.
• Is this probe certified for Zone 0 hazardous areas?
  Yes. With proper intrinsic safety barriers, it meets Class I, Zone 0 ia IIC T5…T1 Ga requirements.
• What is the typical DC resistance I should measure?
  For a 5.0-meter probe, expect 8.73 ± 0.50 Ω between center and outer conductors.
• Does the probe need pressure testing before use?
  Not normally. Bently Nevada does not pressure test each probe. Contact our custom design department if your application demands it.
• How do I choose between the 330190-085-00-CN and 330190-085-00-05 extension cables?
  Both are compatible. The -CN version includes a connector option for specific systems. The -05 is the standard armored extension. Choose based on your existing cable assembly requirements.
• What is the best practice for storing spare probes?
  Store in original packaging. Keep in a dry, temperature-controlled area between -52°C and +177°C. Avoid contact with solvents.
• Can I use this probe with non-Bently Nevada monitoring systems?
  Yes, but verify the system’s input impedance and power supply. For best performance, pair with Bently Nevada Proximitor sensors and 3300 5mm Proximity Probes family.

Selection Guide – Quick Comparison

Use 330192-00-20-50-05 when you need a 5-meter, 8 mm probe with full hazardous area approvals. For shorter system reach, consider pairing with 330190-085-00-CN (with connector option) or 330190-085-00-05 (standard armored). The 5 mm proximity probe family from 3300 5mm Proximity Probes offers alternative tip sizes for different target materials.
