Frequently Asked Questions (FAQ)

• What is the maximum probe length? Available in 1, 5, or 9 meters.
• Can I use this probe without armor? Yes, this model has no armor.
• Does it work in high humidity? Yes, 100% condensing humidity, but connectors must be protected.
• Why is low temperature a concern? Below -34°C (-30°F) may damage the pressure seal.
• Is the pressure seal tested before shipping? No, contact custom design department if needed.
• What torque for the probe case? Recommended 21.1 N•m, maximum 63.3 N•m.
• Can I use it on a small shaft? Minimum recommended shaft diameter is 152 mm.

Experience-Based FAQ & Selection Guide

• Which total length should I choose? Use 1 meter for short reach, 5 or 9 meters for remote monitoring.
• When to order agency approval option? Only if your site requires formal certification. Most users select 00.
• What if my shaft is smaller than 152 mm? Expect higher cross-talk. Use flat target above 30.5 mm instead.
• How do I avoid premature seal failure? Keep temperature above -34°C during operation.
• Need pressure test before use? Request custom test from Bently Nevada before shipment.

Selection Guide

• Step 1: Confirm shaft or target diameter ≥ 152 mm.
• Step 2: Choose unthreaded length (010 = 10 mm).
• Step 3: Select case length (050 = 50 mm).
• Step 4: Pick total probe length (10 = 1.0 m).
• Step 5: Connector type 02 = ClickLoc standard.
• Step 6: Approval 00 unless required.
