Frequently Asked Questions
1. What does the 330104 model indicate?
It identifies a 3300 XL 8 mm proximity probe with M10 × 1 metric threads and armored cable.
2. What does the "50" option mean?
It specifies a 5.0-meter (16.4 ft) total transducer system length.
3. What connector does this probe use?
Option 02 provides a Miniature coaxial ClickLoc® connector with a standard cable.
4. What does the "RU" suffix represent?
It indicates a region-specific approval or certification option. The exact certification should be confirmed using the product nameplate or the Bently Nevada Approvals Quick Reference Guide.
5. Can this probe operate by itself?
