Product Description
The 3300 XL 11 mm Proximity Probes from Bently Nevada measure shaft vibration and position. Model 330709-000-050-10-12-05 uses a M16 x 1.5 thread without armor. It has a 50 mm overall case length and a 1.0 metre total cable length. The probe includes a miniature coaxial ClickLoc connector with FluidLoc cable. This sensor resists moisture and works well in humid environments. Each unit ships new in original factory packing with a 12-month warranty.

Professional FAQ
- What is FluidLoc cable and when should I use it? FluidLoc cable resists moisture wicking inside the connector. Use it in high humidity or condensing environments like paper mills or offshore platforms.
- Why does this probe have multiple approvals (Option 05)? Option 05 means the probe meets safety standards for many countries. You can install it in Europe, North America, and Asia without extra certification.
- Can I use this M16 probe with an M14 mounting hole? No. The thread size is different. Use the correct adapter or order the M14 version (330703 or 330704).
- What happens if I exceed the minimum bend radius? The internal cable may break or change impedance. This causes noisy signals or complete failure. Keep bends larger than 25.4 mm.
- The pressure seal is not factory tested. Should I test it? Only if your application involves high differential pressure. Contact Bently Nevada custom design for pressure testing before installation.
Selection Guide (Buying Advice)
- Pick 330709 for M16 x 1.5 mounting holes without armor
- Choose unthreaded length 000 for standard flush mount
- Select overall case length 050 (50 mm) for most industrial machines
- Use total length 10 (1 meter) for short runs to junction boxes
- Pick connector option 12 with FluidLoc cable for wet or condensing areas
- Choose approval option 05 if your equipment ships to multiple countries
- Need 9 meter cable? Order total length option 90
- Need armor for crush protection? Order 330704 or 330706 instead
- Check your shaft diameter: Must be at least 152 mm for this probe
- Verify target flat diameter: At least 30.5 mm minimum
