Frequently Asked Questions

• Q: What is the advantage of 11mm probe over 8mm?
  A: 11mm probes offer longer linear range (typically 3mm+ vs 2mm for 8mm). Better for large shaft movement, thrust position monitoring, and applications with wider gap variations.
• Q: What thread size does this probe use?
  A: M14 x 1.5 metric thread. This is larger than standard 8mm probes (3/8-24 UNF or M10x1). Ensure your mounting port matches this thread size.
• Q: What approvals does option 05 include?
  A: Multiple Approvals include CSA (North America), ATEX (Europe), and IECEx (international) for global hazardous location use.
• Q: What is the recommended installation torque?
  A: Recommended torque is 21.1 N·m (187 in·lb). Maximum rated torque is 63.3 N·m (560 in·lb). Do not exceed maximum to avoid thread damage.
• Q: Is armor available for this probe?
  A: This model (330703) is without armor. For armored versions, contact Bently Nevada for custom ordering options. Standard cable is suitable for conduit installation.
