Frequently Asked Questions

• Q: Why must 5m probe be used with 5m Proximitor only?
  A: The 5m probe has specific resistance (8.73 Ohms) calibrated for 5m Proximitor Sensor. Using with 9m proximitor or adding extension cables will cause measurement errors.
• Q: What does +20%, -0% length tolerance mean?
  A: The cable may be up to 20% longer than 5.0m but never shorter. Actual length could be 5.0m to 6.0m. This accommodates manufacturing variation.
• Q: What is a reverse mount probe?
  A: Reverse mount probes install from inside the machine casing outward. Use for thrust position measurement or when standard outside mounting is not possible.
• Q: What is the resistance at 5.0 meters?
  A: RPROBE is 8.73 ± 0.70 Ohms. Compare to 0.5m probe (7.45 Ohms) and 9.0m probe (9.87 Ohms).
• Q: Can I use this probe in hazardous locations?
  A: No. Option 00 means no hazardous location certifications. For hazardous areas, choose option 05 (multiple approvals) instead.
