The Bently Nevada 3300/20-11-01-01-00-02 is a specialized dual-channel thrust monitor module engineered for the 3300 series rack systems. It provides critical axial displacement monitoring for rotating machinery such as steam turbines, centrifugal compressors, and large industrial pumps. By tracking thrust position relative to alarm setpoints, this module facilitates early detection of mechanical wear, allowing for proactive maintenance and the prevention of catastrophic bearing failure.
Features
Dual-channel configuration for comprehensive axial position measurement.
Integrated signal conditioning for proximity probe inputs.
Configurable Alert and Danger alarm setpoints with relay output logic.
Front-panel LED status indicators for system health, including OK, Bypass, Alert, and Danger states.
Hazardous area compatibility provided by the integrated barrier option.
Applications
This monitor is primarily utilized in critical asset protection systems within oil and gas, power generation, and petrochemical facilities. It is designed for integration into standard Bently Nevada 3300 monitoring racks to provide continuous, high-reliability vibration and displacement data.
