Industry Applications
The Bently Nevada 330709-000-080-90-02-05 excels in demanding environments such as steam turbines, centrifugal compressors, and large pumps. Its 11 mm probe tip and 9-meter cable allow installation in tight locations while maintaining signal integrity. For example, in a refinery, replacing older 8 mm probes with this 3300 XL version reduces noise floors and improves early fault detection. The cross-talk limitation ensures reliable readings even when probes are mounted close together in dual-probe configurations.
Installation and Setup Guidance
When mounting the Bently Nevada 330709-000-080-90-02-05, ensure the M16x1.5 thread is engaged no more than 24 mm. Use the recommended probe case torque of 21.1 N·m to avoid case damage. The connector-to-connector torque should be finger tight (maximum 0.565 N·m). Route the cable with a minimum bend radius of 25.4 mm (1.0 inch) to prevent internal damage. For best performance, verify the target shaft diameter is at least 152 mm (6.0 in) to satisfy the cross-talk limitation.
Selection Guide
Before purchasing, confirm your system's cable length requirement. The 330709-000-080-90-02-05 comes with a 9.0-meter cable—ideal for most industrial installations. If you need a different length, contact UBEST Automation for assistance with the correct Bently Nevada part number. Always verify the probe's agency approval (Option 05) matches your area's certification needs. For a reliable upgrade or replacement, trust the genuine Bently Nevada 330709-000-080-90-02-05 only from authorized distributors.
