Quick Detail

Description

The 330703-000-050-10-11-05 3300 XL 11 mm Proximity Probe is a high-performance, large-diameter eddy current transducer from Bently Nevada, engineered for robust and precise machinery condition monitoring on critical heavy-duty rotating equipment. As a core component within the advanced 3300 XL monitoring ecosystem, this 11 mm proximity probe is designed to deliver reliable, non-contact measurement of shaft vibration, radial displacement, and axial position in turbines, compressors, generators, and large pumps. Its larger 11 mm sensing tip diameter provides enhanced performance and signal stability, making it particularly suitable for applications requiring a larger sensing area or monitoring on shafts with rougher surface finishes. This model serves as a direct, performance-enhanced successor to legacy 7200-series 11 mm and 14 mm transducer systems, offering a seamless upgrade path to modern monitoring capabilities.

This specific probe is built for simplified installation and exceptional durability. It features a compact overall case length of 50 mm and a minimum unthreaded length of 0 mm, allowing for versatile mounting in standard housings and tight spaces. The probe is supplied with a generous total cable length of 1.0 meter (3.3 feet), which is terminated with a secure miniature coaxial ClickLoc connector and protected by a connector protector. A key feature is the use of FluidLoc cable technology, which provides superior resistance to oils, coolants, and other industrial fluids that can degrade standard cable jackets. Carrying multiple international agency approvals, this 3300 XL probe is certified for use in a wide range of regulated industrial environments, ensuring global compliance and safety.

Applications

This 11 mm proximity probe is ideally suited for monitoring large-scale, critical rotating machinery such as industrial gas turbines, steam turbines, and hydroelectric generators. Its substantial 4.0 mm linear range and robust signal output are perfect for tracking both dynamic vibration and slow-moving axial position (thrust) on these high-value assets, providing essential data for predictive maintenance and avoiding catastrophic failures in power generation facilities.

Acting as a direct, drop-in upgrade for aging 7200-series 11/14 mm transducer systems, this probe is central to modernization projects. It allows plants to enhance their monitoring system's reliability and data quality without changing mounting hardware, leveraging the modern 3300 XL platform's diagnostics while protecting previous mechanical investments, thus minimizing retrofit complexity and downtime.

The integration of FluidLoc cable technology makes this probe exceptionally well-suited for environments where cables are exposed to lubricating oils, hydraulic fluids, or cooling sprays. This makes it an excellent choice for installation on paper mill machinery, metal rolling mill equipment, and large gearboxes where fluid ingress is a common cause of standard cable failure, ensuring long-term signal integrity and reduced maintenance.

Specifications

Competitive Advantage

1. Superior Fluid and Environmental Resistance with FluidLoc Cable

A defining advantage is the integration of FluidLoc cable technology. Unlike standard cables, this specialized design provides exceptional resistance to degradation from oils, coolants, and industrial chemicals. This dramatically extends the cable's service life in wet or fluid-exposed environments, reducing a common failure point and ensuring long-term signal reliability with lower maintenance costs.

2. Large-Diameter Design for Robust and Stable Signal Acquisition

The 11 mm probe diameter offers enhanced performance over smaller probes. It provides a larger sensing area, which can improve signal stability and signal-to-noise ratio when monitoring shafts with less-than-ideal surface conditions or in applications requiring a robust measurement. This makes it a more reliable choice for heavy-duty and critical machinery monitoring.

3. Direct Legacy System Upgrade Path with Modern Performance

Engineered as a direct replacement for obsolete 7200-series transducers, this probe offers a straightforward upgrade solution. It delivers the advanced performance, reliability, and compatibility of the modern 3300 XL platform while fitting into existing mechanical mountings, allowing users to modernize their protection systems without costly mechanical rework, thereby future-proofing their operations.

4. Certified Reliability for Global Industrial Deployment

Carrying multiple international agency approvals, this probe is pre-certified for use in a wide array of regulated markets and industrial sectors. This simplifies the specification and procurement process for global projects, ensures compliance with regional safety standards, and guarantees that the product meets stringent quality and performance benchmarks for worldwide deployment.
