Frequently Asked Questions

• Q: What approvals does the 05 option include?
  A: Option 05 includes CSA for North America, ATEX for Europe, and IECEx for international hazardous locations. This probe works globally without needing different models for each region.
• Q: What is the maximum wall thickness for this 0.8 inch probe?
  A: Safe maximum is 0.2 inches (5 millimeters). Calculation: 0.8 inch case minus 0.5 inch minimum thread engagement minus 0.06 inch gap minus 0.04 inch safety margin equals 0.2 inches maximum.
• Q: Can I use this probe in temperatures below -34 degrees Celsius?
  A: The probe operates to -52 degrees Celsius, but Bently Nevada warns that the Viton pressure seal may fail prematurely below -34 degrees Celsius. For sustained cold operation, contact Bently about special sealing materials.
• Q: What is the difference between approval option 00 and 05?
  A: Option 00 has no hazardous location certifications. Option 05 includes CSA, ATEX, and IECEx for use in explosive atmospheres. Use option 05 for refineries, chemical plants, and gas handling facilities.
• Q: Does the 0.5 meter cable limit my installation distance?
  A: You can add 3300 XL extension cables to reach longer distances. Total system length (probe cable plus extension) must match your proximitor calibration. Example: 0.5 meter probe plus 4.5 meter extension equals 5.0 meter system.
