Bently Nevada 3500/53 133388-01 Overspeed Detection Module

Function Features

• Ultra-Precise and Rapid Overspeed Detection: It adopts digital signal processing technology, achieving a high resolution of 0.01 RPM and an accuracy of ±0.02%. The response time of less than 1 millisecond allows it to capture overspeed conditions instantly and trigger protective measures, avoiding catastrophic equipment failures.
• Redundant Design for High Reliability: It is equipped with a dual-channel redundant design that supports cross-validation of data between channels. The configurable voting systems further enhance the stability of the protection system, ensuring continuous operation even if individual components malfunction.
• Comprehensive Self-Diagnostic Capabilities: The built-in self-diagnostic function enables early detection of internal component faults and quick location of fault points. This reduces the difficulty of troubleshooting and maintenance, lowers maintenance costs, and shortens equipment downtime.
• Flexible Integration and Communication: It supports Modbus RTU/TCP protocols to communicate smoothly with distributed control systems and supervisory control and data acquisition platforms. The optional relay and analog output signals allow it to adapt to different connection needs of various industrial control systems.
• Convenient Installation and Configuration: It comes with complete supporting accessories and a detailed operation manual. Its compact size allows for easy installation in the 3500 rack. The user-friendly configuration method enables both professional engineers and maintenance personnel to complete setup and parameter adjustment efficiently.

Application Scenarios

• Power Industry: It is widely used in steam turbines, gas turbines, and generators in thermal power, hydropower, and gas power plants. It prevents serious accidents such as equipment damage and power outages caused by overspeed of power generation equipment, ensuring the stable operation of the power grid.
• Oil and Gas Industry: It is installed on centrifugal compressors, pipeline pumps, and gas transmission equipment in oil fields and natural gas processing plants. It adapts to flammable and explosive field environments and avoids leaks and explosions caused by overspeed-induced mechanical failures of key transmission equipment.
• Heavy Manufacturing Industry: It is applied to rotating equipment such as rolling mill main motors and blast furnace fans in metallurgical plants. It can withstand high temperatures and high dust in smelting sites, ensuring the continuity of the metallurgical production process by preventing overspeed faults of core equipment.
• Chemical Industry: It is used for overspeed protection of reactor agitators, centrifuges, and material delivery pumps in chemical plants. It ensures the safe operation of chemical production equipment, avoiding dangerous situations such as material leakage and reaction out of control due to equipment overspeed.
• General Industrial Equipment: It provides overspeed protection for large water pumps in water treatment plants, main engines of mining machinery, and high-speed fans in paper mills. It meets the basic overspeed monitoring needs of various general rotating equipment and reduces economic losses caused by unplanned shutdowns.
