Bently Nevada 3500/54M 286566-01 Tachometer and Overspeed Detection Module

Function Features

• Comprehensive Speed Monitoring: It can measure shaft speed, rotor acceleration, and rotor direction while providing zero-speed notification. It covers all key rotational parameters of machinery, which offers complete data support for equipment status analysis and fault diagnosis.
• Multi-Mode Alarm Configuration: It supports multiple alarm functions such as setpoint alarming, speed band alarming, and rotor acceleration alarming. Users can program alarm thresholds according to actual working conditions, which ensures timely alerts for abnormal speed-related conditions.
• System-Oriented Signal Sharing: It can supply conditioned keyphasor signals to the backplane of the 3500 rack. This realizes information interconnection with other monitors in the system, avoiding independent operation of a single module and improving the overall coordination and monitoring efficiency of the 3500 series protection system.
• Strong Environmental Adaptability: It is made of high-grade materials and has excellent durability. It can work stably in extreme temperature environments ranging from -40°C to +70°C. Its robust structure enables it to resist the impact of dust, vibration, and other harsh industrial factors.
• User-Friendly Operation and Integration: It is equipped with a user-friendly interface that simplifies setup and configuration processes. It supports Ethernet and RS485 connections and is fully compatible with the 3500 series machinery protection system, which minimizes installation and integration time and reduces operational downtime.

Application Scenarios

• Power Generation Industry: It is widely used in steam turbines, gas turbines, and generators in thermal power and hydropower stations. It monitors rotor speed and acceleration in real time to prevent equipment damage and large-scale power outages caused by overspeed, which guarantees the continuous and stable operation of the power grid.
• Oil and Gas Industry: It is installed on centrifugal compressors, pipeline pumps, and turboexpanders in oil fields and natural gas processing plants. It adapts to the harsh on-site environment and avoids safety accidents such as leaks and explosions due to speed abnormalities of transmission equipment during oil and gas extraction and transportation.
• Manufacturing Industry: It is applied to rotating equipment such as motors, gearboxes, and fans in automated production lines. It monitors the speed status of key equipment to prevent production line shutdowns caused by equipment failures, which helps maintain efficient operation of the production process.
• Turbomachinery Field: It provides specialized monitoring for various turbomachinery including air compressors and turbochargers. It accurately captures subtle changes in rotor speed and acceleration to assist in early detection of potential faults such as rotor imbalance, which extends the service life of turbomachinery.
• Heavy Machinery Industry: It is configured on mining crushers, conveyor drive systems, and large construction machinery. It withstands high dust and strong vibration in the working environment and ensures that the speed of heavy machinery remains within the safe range to avoid accidents during high-load operation.
