Applications and Cost Benefits

The 330141-08-20-11-00 excels in critical turbomachinery monitoring, such as steam turbines, compressors, and pumps. Its armored design and FluidLoc cable prevent fluid leakage and mechanical damage, reducing environmental cleanup costs and production losses. Additionally, the high pull strength of the CableLoc design minimizes false alarms, cutting unnecessary maintenance dispatches. By delivering precise, repeatable measurements, this probe helps avoid catastrophic failures, which can cost millions in lost production.

Installation and Integration

Install the probe according to Bently Nevada guidelines, ensuring proper mounting and cable routing. The miniature coaxial ClickLoc connector with protector simplifies connection and protects against contamination. For integration with 3300 XL systems, verify compatibility with your monitor and extension cable. No specific wiring or configuration values are provided here; refer to official documentation.

Maintenance and Reliability

Periodic inspection of the probe tip and cable is recommended. Check for physical damage, fluid ingress, or loose connections. The armored construction and FluidLoc option reduce wear and fluid-related failures, extending maintenance intervals. Operating within specified temperature and humidity ranges ensures optimal performance and longevity. These factors contribute to lower lifecycle costs and improved plant availability.
