Bently Nevada 3500/50-01-00 Two-Channel Tachometer Monitoring Module

Function Features

• Comprehensive Rotational Parameter Monitoring: It achieves all-round monitoring of rotational speed, rotor acceleration, and rotation direction of rotating machinery. It can effectively detect zero-speed and reverse rotation states of equipment, providing comprehensive data support for judging the operational status of machinery.
• Programmable Alarm and Flexible Configuration: It supports setting programmable alarm thresholds. Users can customize alarm criteria according to different equipment operating requirements. It matches the 3500 rack configuration software and allows flexible functional configuration to meet diverse monitoring needs of different industrial scenarios.
• Peak Hold and Data Recording: It has a peak hold function that stores maximum speed, maximum reverse speed, or the number of reversals of the equipment. This function helps maintenance personnel track extreme operating conditions of the equipment and conduct in-depth analysis on potential fault risks.
• Keyphasor Signal Sharing: It outputs keyphasor signals to the 3500 rack backplane. Other monitoring modules in the rack can directly use these signals, simplifying the overall structure of the monitoring system and reducing the cost of configuring separate keyphasor modules.
• Simplified Wiring with Internal Termination: It is equipped with an internal termination I/O module. This design shortens the wiring distance between the module and sensors, reduces signal interference and wiring faults, and improves the efficiency of on-site installation and later maintenance.
• Redundant Configuration and Hot Swapping: It supports redundant power supply and rack configurations to ensure continuous operation of the monitoring system when local components fail. All modules and power supplies can be hot-swapped in the rack, avoiding system shutdowns caused by module maintenance or replacement.

Application Scenarios

• Power Industry: It is widely used in steam turbines, generators, and water pumps in thermal power and hydropower stations. It monitors rotational speed anomalies in real time and triggers alarms quickly to prevent major power outages caused by equipment damage, ensuring the stable operation of the power grid and continuous power supply.
• Petrochemical Industry: It is installed on centrifugal compressors, screw pumps, and pipeline transport machinery in oil refineries and natural gas processing plants. It adapts to harsh environments with flammable and explosive gases and high temperatures. It prevents safety accidents such as pipeline leakage and material backflow due to speed abnormalities, ensuring the smooth progress of oil and gas production and transportation.
• Metallurgical Industry: It is applied to rolling mills, blast furnace fans, and crushers in steel plants and non-ferrous metal smelters. It can operate stably in high-dust and large temperature-difference environments. It monitors equipment speed to ensure that the production process meets set standards and reduces production interruptions caused by mechanical failures.
• Paper and Machinery Industry: It is used for speed monitoring of motors and transmission systems in papermaking machines, oxygen generators, and large fans. It provides continuous online monitoring for the equipment, helps avoid unplanned shutdowns of production lines, and ensures the continuity and efficiency of the production process.
• Marine Power Field: It is configured on marine diesel engines and shipborne power generation equipment. It resists the corrosion of salt mist in the marine environment and stably monitors the rotational parameters of marine power equipment. It ensures the stable output of marine power and provides reliable guarantee for the safe navigation of ships.
