Installation Guide

1. Mounting: Snap onto 35 mm DIN rail (TH35-15 or TH35-7.5).
2. Power Supply: Connect -17.5 Vdc to -26 Vdc. Max current: 12 mA.
3. Probe & Cable: Connect 3300 XL 11 mm probe and extension cable. Total length must equal 5.0 meters.
4. Output Wiring: Connect shielded cables to monitoring system. Ground shield at one end.
5. Gap Calibration: Set probe gap per application requirements. The 11 mm system provides 4.0 mm linear range.

FAQ

Q: What is the difference between 3300 XL 8 mm and 11 mm systems?
A: The 11 mm system has a larger probe tip (11 mm vs. 8 mm) and extended linear range (4.0 mm vs. 2.0 mm). It is used for large-gap applications like axial position and differential expansion. The 8 mm system is standard for radial vibration.

Q: Can I mix 8 mm and 11 mm components?
A: No. The 3300 XL 11 mm system requires all 11 mm components (probe, cable, Proximitor). Do not mix with 8 mm components.

Q: What monitoring system is required for 11 mm systems?
A> If using a 3500 Monitoring System, an updated configuration software version listing the 3300 XL 11 mm system as compatible is required. Existing 3300 monitoring systems may need modification.

Selection Tips

• Choose 3300 XL 11 mm for axial position, differential expansion, and rod drop applications requiring >2.0 mm linear range.
• Choose 3300 XL 8 mm for standard radial vibration and position measurement.
• When upgrading from 7200-series 11 mm/14 mm, replace all components with 3300 XL 11 mm equivalents.
• Verify monitoring system compatibility before ordering 11 mm systems.
