Frequently Asked Questions

• Q: What length options are available for reverse mount probes?
  A: Standard lengths are 0.5m, 1.0m, 2.0m, 5.0m, and 9.0m. The 2.0m option (146055-20-02-00) offers moderate reach with good signal strength. Choose based on your proximitor mounting distance.
• Q: Can I add extension cable to this 2.0m probe?
  A: Yes. Total system length (probe cable + extension) must match proximitor calibration. Example: 2.0m probe + 3.0m extension = 5.0m system. Example 2: 2.0m probe + 7.0m extension = 9.0m system.
• Q: What is a reverse mount probe?
  A: Reverse mount probes install from inside the machine casing outward. Use for thrust position measurement, limited access areas, or when standard outside mounting is not possible due to space constraints.
• Q: Can I use this probe in hazardous locations?
  A: No. Option 00 means no hazardous location certifications. This probe is for safe area (non-classified) use only. For hazardous areas (Class I, Div 2 or Zone 2), choose option 05 (multiple approvals).
• Q: What is the resistance difference between cable lengths?
  A: 0.5m = 7.45 Ohms, 1.0m = 7.59 Ohms, 2.0m = 7.88 Ohms, 5.0m = 8.73 Ohms, 9.0m = 9.87 Ohms. Longer cables have higher resistance.
