BENTLY 330104-11-25-10-02-00
Product Introduction
The Bently Nevada 330104-11-25-10-02-00 is a premium 11mm proximity probe assembly designed for critical machinery monitoring in demanding industrial applications. As part of Bently Nevada’s 3300 XL series, this complete transducer system provides precise measurement of shaft vibration, position, and eccentricity in turbines, compressors, and other high-speed rotating equipment.
Engineered for reliability, the assembly includes a high-temperature rated probe, 10-meter integral cable, and military-style connector for secure signal transmission. The Inconel 600 tip material provides exceptional wear resistance in abrasive environments, while the 316 stainless steel housing ensures long-term performance in corrosive conditions.
Core Advantages and Technical Highlights
Extended range measurement:
The Bently Nevada 330104-11-25-10-02-00 offers an expanded 2.3mm measurement range compared to standard probes, making it ideal for applications with large shaft movements. The 7.87 V/mm sensitivity maintains precision across the full range, with ±1% linearity for trustworthy data.
High-temperature capability:
With a -40°C to +177°C operating range, this probe assembly performs reliably in extreme environments like gas turbine exhaust sections or high-temperature steam applications. The Inconel 600 tip resists oxidation and maintains calibration stability at elevated temperatures.
Robust mechanical design:
The 11mm diameter probe body provides enhanced durability in high-vibration applications. The 316 stainless steel construction resists corrosion in offshore and chemical plant environments. The 10-meter integral cable reduces connection points that could compromise signal integrity.
Comprehensive system integration:
The assembly includes a pre-calibrated extension cable and military-style connector for direct compatibility with Bently Nevada 3300 XL monitoring systems. The API 670 compliance ensures suitability for critical refinery and petrochemical applications.
Typical Application Scenarios
Gas turbine monitoring:
The Bently Nevada 330104-11-25-10-02-00 is ideal for measuring turbine shaft eccentricity during startup, where large thermal growth occurs. Its high-temperature rating allows installation near hot gas paths.
Hydrogen compressors:
In refinery service, the probe’s Inconel tip resists hydrogen embrittlement while monitoring shaft position in high-pressure compressors. The 10m cable accommodates large machine layouts.
Paper mill machinery:
The 316 stainless construction withstands corrosive pulp chemicals while monitoring roll grinding equipment. The extended measurement range accommodates large roll movements.
Offshore platform pumps:
The ATEX-certified assembly provides vibration monitoring in hazardous areas. The integral cable survives constant platform vibrations and salt spray exposure.
