What Makes the 330191-00-08-50-00 Essential for Reliable Machine Monitoring?
How can engineers maintain precise vibration measurement in harsh industrial environments? The Bently Nevada 330191-00-08-50-00 delivers engineering-grade precision through its 3300 XL 8 mm ETR probe design. This proximity probe features a 3/8-24 UNF thread and a 5.0-meter total length, making it ideal for extended reach applications. Its robust construction ensures accurate displacement measurements, even under extreme conditions.
Key Specifications of the 330191-00-08-50-00

Applications and Use Cases
The 330191-00-08-50-00 excels in turbomachinery monitoring, such as steam turbines and compressors. Because of its 5-meter length, it suits installations where the Proximitor sensor is distant. Additionally, the ETR cable withstands high temperatures, ensuring reliability in extreme environments. This probe also integrates seamlessly with Bently Nevada extension cables and Proximitor sensors for complete system compatibility.
Installation and Setup
Install the probe using the 3/8-24 UNF thread, ensuring maximum engagement of 0.563 inches. Connect the probe to a compatible 5-meter Proximitor sensor only. Verify that the input voltage remains within -17.5 Vdc to -26 Vdc to avoid reduced linear range. For nonincendive circuits, follow installation drawing 140979.
Maintenance and Reliability
Inspect the probe periodically for physical damage or wear. The patented TipLoc and CableLoc designs enhance durability, providing 330 N pull strength. The Viton O-ring seals against differential pressure, though probes are not pressure tested. Avoid operation beyond the specified temperature schedule to prevent degradation.
