Bently Nevada 200350-09-00-01 Accelerometers

The Bently Nevada 200350-09-00-01 serves as a high-precision seismic transducer for permanent industrial monitoring. This general-purpose accelerometer measures casing vibration to assess the health of rotating machinery. It features a rugged stainless steel design for continuous operation in extreme environments. The hermetically sealed housing protects the internal piezoelectric core from industrial contaminants. Furthermore, the sensor provides stable data output for safety-critical condition monitoring.

Technical Specifications

Core Functional Principles

This accelerometer utilizes an internal piezoelectric element to convert mechanical motion into electrical signals. It captures vibration data along its sensitive axis with high linear accuracy. The device then generates a differential voltage signal proportional to the detected acceleration. This specific model facilitates early detection of rotor-related malfunctions like unbalance. Moreover, the top-mounted MIL-C-5015 connector allows for rapid cable replacement without disturbing the sensor mount.

System Compatibility and Integration

The 200350-09-00-01 integrates seamlessly with the Bently Nevada Trendmaster Pro system architecture. It connects directly to Seismic Direct Input Cards and Constant Current cards. These modules supply the necessary excitation current for the IEPE circuitry. Because of this standardized interface, the sensor simplifies the deployment of large-scale monitoring networks. The 1/4-28 threaded base ensures a stiff mechanical connection for high-frequency signal clarity.

Primary Industrial Applications

Maintenance teams deploy this sensor on bearing housings for motors, pumps, and fans. It performs reliably in the humid conditions of cooling towers and refineries. The robust casing withstands the high-vibration levels typical of power generation equipment. By tracking casing vibration trends, the sensor enables effective predictive maintenance strategies. Consequently, operators can schedule repairs before catastrophic mechanical failures occur.
