1900/65A Bently Nevada Vibration Monitoring System Multi Channel Stainless High

Product Specification

​1. Product Overview: Bently Nevada 1900/65A Proximity Transducer System

​
The Bently Nevada 1900/65A is a high-precision proximity transducer system designed for continuous monitoring of radial vibration, axial displacement, and shaft speed in rotating machinery. This system comprises an eddy current probe, extension cable, and preamplifier, engineered to deliver reliable performance in extreme industrial environments. The probe, constructed with corrosion-resistant stainless steel, operates in temperatures ranging from -40°C to +150°C and is rated IP67 for protection against dust and moisture. Utilizing non-contact eddy current technology, it detects minute changes in shaft position and vibration, providing critical data to prevent equipment failures in turbines, compressors, pumps, and motors. Ideal for oil and gas, power generation, and heavy manufacturing, the 1900/65A ensures operational safety and efficiency through real-time diagnostics.

​3. Industrial Applications and Use Cases

​
The 1900/65A is critical for monitoring shaft dynamics in gas turbines, steam turbines, and centrifugal compressors, where it detects misalignment, bearing wear, or rotor imbalance. In offshore oil platforms, it ensures safe operation of subsea pumps exposed to corrosive saltwater and high humidity. Power plants deploy this system to safeguard boiler feed pumps and generator shafts, while wind turbine operators rely on it for gearbox health monitoring. Its ATEX/IECEx certification allows deployment in explosive atmospheres, such as petrochemical refineries and LNG processing units. Additionally, it supports hydrodynamic bearing monitoring in hydroelectric turbines, enhancing operational reliability in renewable energy systems.

​4. Competitive Advantages and Unique Features​

• ​Non-Contact Sensing: Eddy current technology eliminates mechanical wear, ensuring long-term accuracy and minimal maintenance.
• ​Hazardous Area Compliance: ATEX/IECEx Zone 1/21 certification for explosive gas and dust environments.
• ​High-Temperature Resilience: Stainless steel probe withstands thermal cycling and aggressive media.
• ​Plug-and-Play Integration: Pre-calibrated system simplifies installation with standardized connectors.
• ​API 670 Compliance: Meets global standards for machinery protection systems in critical industries.

​5. Functional Capabilities and Operational Benefits

​
The 1900/65A provides real-time data to control systems, enabling predictive maintenance and automated shutdowns to avoid catastrophic failures. Its wide frequency response captures dynamic events like rotor rubs or sudden unbalance, while the linear output integrates seamlessly with Bently Nevada’s 3500 series monitors and third-party PLCs/SCADA systems. The IP67 rating ensures durability in wet or dusty environments, reducing maintenance costs. By aligning with API 670 standards, it guarantees compliance in regulated industries, minimizing operational risks. These features make the 1900/65A a cost-effective solution for extending equipment lifespan and optimizing asset performance in demanding industrial settings.
