Real-World Use & Application Scenarios
The Bently Nevada 3500/93 135785-02 System Display Unit is vital for providing operators and maintenance personnel with a clear visual interface to monitor machinery protection system data in real time. Widely used in power plants, petrochemical facilities, and heavy industry, it helps visualize critical alarms, system statuses, real-time data, and historical trends for machinery like turbines, compressors, and motors. The display enhances situational awareness for control room operators, enabling quick decision-making that supports safe and efficient plant operation. This module addresses the need for ergonomic and clear industrial monitoring in environments that comply with API Standard 670 for machinery protection.
Product Introduction & Positioning
The 3500/93 135785-02 is a backlit display unit designed to work with the Bently Nevada 3500 Series machinery protection system. It features a high-resolution color LCD screen with 1280 x 800 pixel resolution and a 16:10 aspect ratio, offering high visibility including in low-light conditions due to its backlighting. The unit provides detailed display of alarms, event lists, and channel status, offering a user-friendly interface configured using 3500 Rack Configuration Software. Positioned as the primary human-machine interface (HMI) for the 3500 system, the display unit can be mounted in various ways including face, rack, panel, or independent mounting, and supports remote viewing with cable lengths up to 100 feet (extendable to 4000 feet with external power supplies).
