Bently Nevada 3500/50 133388-02 Two-Channel Tachometer Monitoring Module

Function Features

• Comprehensive Speed Parameter Monitoring: It achieves all-round monitoring of rotational speed, rotor acceleration, and rotation direction of rotating machinery. The four configurable modes cover speed band alarming, zero-speed notification, rotor acceleration alarming, and reverse rotation notification, fully meeting the personalized monitoring needs of different industrial scenarios.
• High-Precision and Rapid Response: It adopts advanced signal processing algorithms, which enables it to maintain high measurement accuracy. Its ultra-short response time allows it to quickly capture sudden changes in equipment speed, ensuring that abnormal conditions are detected and alarmed in a timely manner to avoid serious equipment damage.
• Backplane Signal Sharing: It provides conditioned keyphasor signals for the 3500 rack backplane. This design simplifies the overall structure of the monitoring system, reduces the cost of configuring additional modules, and enhances the coordination and operational efficiency among various modules in the system.
• Practical Peak Hold and Reset: Its peak hold function can store critical peak data during equipment operation. Users can reset these peak values as needed, which helps maintenance personnel track extreme operating conditions of the equipment and conduct in-depth analysis of potential fault risks.
• Strong System Compatibility: It can be perfectly integrated with the 3500 series rack system. It supports collaborative work with other monitoring modules in the system and is compatible with multiple industrial control systems, allowing for smooth data transmission and sharing with upper-level DCS and SCADA systems.

Application Scenarios

• Power Industry: It is installed on turbines, generators, and transformers in power plants and substations. It monitors the rotational speed and acceleration of the equipment during startup, operation, and shutdown. It promptly alarms for anomalies such as overspeed or zero-speed, preventing major power outages caused by equipment damage and ensuring stable power supply.
• Oil and Gas Industry: It is applied to rotating equipment such as centrifugal compressors, oil transfer pumps, and drilling machinery in oil and gas extraction, transportation, and processing facilities. It monitors reverse rotation and speed fluctuations of the equipment, avoiding pipeline blockages or leakage accidents caused by equipment speed failures.
• Metallurgy and Mining Industry: It is used for speed monitoring of crushers, rolling mills, and blast furnace fans in metallurgical and mining sites. It adapts to harsh on-site environments with dust and large temperature differences and ensures that the speed of the equipment meets production process requirements, reducing the probability of production interruptions due to mechanical failures.
• Chemical and Pharmaceutical Industry: It monitors key rotating equipment such as reaction kettle agitators and material conveying pumps in chemical and pharmaceutical production lines. It prevents production accidents and unqualified products caused by speed instability of mixing equipment, and complies with the strict safety and stability requirements of the chemical and pharmaceutical production processes.
• General Manufacturing Industry: It is deployed on motors, water pumps, and conveyor belt driving devices in production lines of automobile manufacturing, papermaking, and textile industries. It maintains the stable operation speed of the production line equipment, improves production efficiency, and extends the service life of the production line equipment by timely alerting speed deviations.
