Product Description
The 3300 XL 11 mm Proximity Probes from Bently Nevada deliver reliable shaft vibration and position monitoring. Model 330703-000-060-10-02-CN uses a M14 x 1.5 thread without armor. It has a 60 mm overall case length and a 1.0 metre total cable length. The probe includes a miniature coaxial ClickLoc connector for secure attachment. This sensor works in harsh industrial environments like turbines and compressors. Each unit ships new in original factory packing with a 12-month warranty.

Frequently Asked Questions (FAQ)
- What is the difference between 330703 and other 3300 XL probes? This version has M14x1.5 thread, 60 mm case, 1 m cable, no armor, and ClickLoc connector.
- Can I use this probe in a high moisture area? Yes. The FEP cable and PPS tip resist moisture well. Keep connector dry.
- How do I check if my existing extension cable works? Use only 75 ohm triaxial cable. Bently Nevada extensions are best.
- Why does resistance show 5.9 ohms for 1m probe? That is the center to outer conductor resistance. It confirms cable health.
- What happens if I over-torque the probe case? Over 63.3 N·m can strip threads or crack the case. Always stay below max.
- Can I cut the cable to a shorter length? No. Cutting changes impedance and calibration. Order exact length needed.
- Which gap should I set for best sensitivity? Set gap between 0.5 mm and 2.5 mm for linear response and low noise.
Selection Guide
- Choose unthreaded length 000 for standard mount
- Pick overall case length based on your mounting depth (060 = 60 mm)
- Select total cable length: 1, 5, or 9 meters only
- Use ClickLoc (02) for easy locking in tight spaces
- Need high temperature? Check T class against your max temp
- Avoid -34°C operation to protect pressure seal life
- For magnetic fields above 300 gauss, use 5m system or shield cable
