Bently Nevada 3500/50M Two-Channel Tachometer Module

Function Features

• Dual-Channel High-Precision Monitoring: It has two independent channels that can accept 1 to 2 proximity transducer signals simultaneously. It accurately captures rotational speed, rotor acceleration, and rotation direction data, which lays a solid foundation for judging the operational status of rotating machinery.
• Comprehensive Self-Checking and Fault Tolerance: It is designed with extensive self-checking functions and fault-tolerant features. It can detect its own operational faults in a timely manner, reduce the risk of monitoring failures, and maximize the reliability of the entire monitoring system during long-term operation.
• Peak Hold and Data Recording: It is equipped with a peak hold function that stores the highest speed, highest reverse speed, and the number of reverse rotations that the machinery reaches during operation. This data provides effective support for maintenance personnel to analyze the extreme operating conditions of the equipment and predict potential faults.
• Flexible Redundancy and Configuration: It supports various redundancy configuration levels, from simplex modules to dual power supplies, and even redundant relay modules. Users can configure complex relay logic through flexible logical operator options to meet the monitoring needs of different complex industrial scenarios.
• Diversified Certification and Wide Compatibility: It holds multiple industry certifications and is compatible with various locally or remotely installed displays. It can be seamlessly integrated with plant control and automation systems through a communication gateway module, enhancing its adaptability in different system architectures.
• Secure and Stable Data Transmission: It offers encrypted communication options to protect data during transmission from tampering or theft. The network redundancy function ensures the continuity and integrity of data transmission even when some network components fail.

Application Scenarios

• Petrochemical Industry: It is widely used in centrifugal compressors, pipeline pumps, and reaction kettle agitators in oil refineries and chemical plants. It adapts to flammable and explosive harsh environments and prevents equipment damage and production accidents caused by rotational speed anomalies, thus ensuring the safe and stable operation of the production process.
• Power Industry: It is installed on steam turbines, generators, and boiler feed pumps in thermal power, hydropower, and nuclear power plants. It monitors the rotational speed parameters of key power equipment in real time and triggers alarms promptly when abnormalities occur, avoiding large-scale power outages caused by equipment failures.
• Marine Industry: With optional DNV and NK maritime certifications, it is suitable for marine diesel engines, shipborne generators, and other equipment. It can resist salt fog corrosion and humid marine environments, ensuring the stable operation of ship power systems and providing a guarantee for safe navigation.
• Metallurgical Industry: It is applied to rotating equipment such as blast furnace fans, rolling mill main motors, and crusher drive systems in steel and non-ferrous metal smelters. It can work stably in high-dust and large-temperature-fluctuation environments and ensures the continuity of the metallurgical production process.
• General Manufacturing Industry: It is used for rotational speed monitoring of motors, fans, and transmission gears in machinery manufacturing workshops, paper mills, and cement plants. Its low-cost advantage makes it an ideal solution for general machinery that requires continuous monitoring. It reduces economic losses caused by unplanned equipment shutdowns.
