Product Overview
The Bently Nevada 330709-000-080-90-11-00 is a precision 3300 XL 11 mm Proximity Probe engineered for non-contact vibration and position measurement in critical rotating machinery. This exact configuration features an M16x1.5 thread with no armor, an 80 mm case length, and a 9.0-meter total cable. It comes equipped with a miniature coaxial ClickLoc connector and FluidLoc cable, ensuring reliable signal transmission in demanding industrial environments. Manufactured in the USA, this probe serves as a direct replacement for older 3300 series probes, offering enhanced durability and consistent performance.
Key Applications
The Bently Nevada 330709-000-080-90-11-00 is specifically designed for monitoring shaft vibrations and axial position in steam turbines, centrifugal compressors, pumps, and large electric motors. Its robust construction provides accurate data for predictive maintenance, reducing unplanned downtime. The probe's 11 mm diameter and 9.0 m cable length make it suitable for installations where sensor placement is remote from the monitoring system. By integrating this probe into existing 3300 XL systems, operators gain precise real-time insights into machine health, supporting effective condition-based maintenance strategies.
Installation Guide
Proper installation of the Bently Nevada 330709-000-080-90-11-00 is critical for accurate readings. Begin by cleaning the mounting surface to remove debris. Use the M16x1.5 thread with a recommended torque per the probe case specification (finger tight for the connector and the specified torque for the case). Route the cable away from sharp edges and maintain a minimum bend radius to prevent damage. Secure the ClickLoc connector firmly so that the connector protector locks into place. After installation, verify the probe gap voltage according to system guidelines to ensure correct operation.
Maintenance Tips
Regular maintenance of the Bently Nevada 330709-000-080-90-11-00 extends its service life. Inspect the cable and connector for signs of wear, corrosion, or cuts. Clean the probe tip periodically with a soft cloth to remove contaminants that could affect performance. Check that the mounting torque remains within recommended limits; re-tighten if necessary. If system readings become erratic, measure the DC resistance of the probe circuit and compare it to factory specifications. Replace the probe if resistance deviates significantly. Proper storage in a dry, temperature-controlled environment when not in use prevents premature aging.
Selection Guide
When selecting a replacement probe, verify that the configuration matches your existing system. The Bently Nevada 330709-000-080-90-11-00 is intended for 3300 XL monitoring systems and can replace older 3300 series probes with the same thread and cable length. The part number breakdown (see Parameters) helps identify the exact specifications. For assistance with cross-referencing other part numbers or confirming compatibility, contact ubest101—a trusted supplier of industrial automation spares. Ensure that the thread type (M16x1.5), cable length (9.0 m), and connector type (ClickLoc) align with your installation requirements to avoid delays.
