Bently Nevada 3500/50 Two-Channel Tachometer Monitor Module

Function Features

• Diversified Parameter Monitoring: It can comprehensively monitor multiple core parameters of rotating machinery, including rotational speed, rotor acceleration, zero speed and rotational direction. The four configurable options through software can flexibly meet the customized monitoring needs of different industrial scenarios for rotating machinery.
• Keyphasor Signal Provision: It can supply conditioned keyphasor signals to the backplane of the 3500 rack. Other monitoring modules in the same rack can directly use these signals, which simplifies the system structure and reduces the cost of configuring independent keyphasor modules.
• Peak Hold and Alarm Functions: It is equipped with a peak hold function that can store the highest speed, highest reverse speed or the number of reverse rotations of the equipment. It supports user – programmable alarm setpoints, and timely generates alarm signals when the monitored parameters exceed the set thresholds to remind relevant personnel to deal with potential risks.
• Convenient Maintenance and High Compatibility: It supports hot – swap operation, which ensures that the replacement and maintenance of the module will not affect the normal operation of the entire 3500 system. It can work with the 3500 rack system and is compatible with multiple industrial communication protocols such as Modbus and Ethernet/IP, realizing seamless integration with DCS and SCADA systems.
• Strong Fault Tolerance and Stability: It adopts internal voting logic between two transducers to minimize false alarms and improve the accuracy and reliability of monitoring data. It uses high – quality electronic components and is designed to withstand harsh industrial environmental conditions, ensuring stable operation in high – temperature, high – humidity and other harsh environments.

Application Scenarios

• Power Industry: It is applied to steam turbines and generator sets. It monitors parameters such as rotor speed and acceleration in real time. For steam turbines with small axial and radial gaps, it can quickly alarm when abnormal speed changes occur, preventing collision damage between the rotor and stator and ensuring the continuous and stable operation of power generation equipment.
• Petrochemical Industry: It is installed in centrifugal compressors in natural gas transmission stations and ethylene plant compression units. It monitors the rotational speed and reverse rotation status of the equipment. It avoids equipment damage caused by reverse rotation of the compressor and prevents production interruptions and safety accidents caused by equipment failures.
• Metallurgical Industry: It is used for rotating equipment such as blast furnace fans and rolling mill motors in metallurgical plants. It monitors the zero – speed state and speed changes of the equipment during startup and shutdown. It helps operators grasp the equipment operation status in time and avoids mechanical failures caused by improper speed control.
• General Manufacturing Industry: It is used in rotating machinery such as water pumps and fans in automobile manufacturing and machinery processing production lines. It monitors the speed parameters of the equipment to ensure that the production line runs at the set speed, improving production efficiency and the qualification rate of finished products.
• Marine and Shipping Industry: It is applied to marine diesel engines and ship – borne power generation equipment. It adapts to the harsh marine environment and monitors the rotational speed and acceleration of the engine rotor. It ensures the stable output of marine power and provides reliable guarantee for the safe navigation of ships.
