Professional FAQ

• Is this probe different from a standard 11 mm probe? Yes. This is a reverse mount design. It installs from behind the target. Use it when front access is blocked.
• Can I pressure test this probe myself? Bently Nevada does not test it before shipping. Contact their custom design department if your job needs a test.
• What happens if I overtighten the connector? The max torque is 0.565 N•m (5 in•lb). Overtightening can break the connector.
• Experience: The cable is too short. Can I extend it? No. Use a 5m or 9m probe instead. Extending the cable changes resistance and causes errors.
• Selection guide: Which thread should I pick – M10 or M16? Pick M10 for small machines with tight mounting space. Pick M16 for larger industrial frames.
