The Bently Nevada 3701/60 177989-02 Wind Turbine Monitor is a monitoring device specifically designed for wind turbine generators. It is mainly used for condition monitoring and fault diagnosis of key mechanical components of wind turbine generators. It can help users prevent potential machine failures through real-time monitoring, improve operational efficiency, and reduce downtime. This device focuses on high-reliability applications such as tower sway, bearing and gearbox monitoring.
Main Functions
Vibration Monitoring: Perform vibration analysis on important mechanical components inside the wind turbine (such as the main shaft, gearbox, generator, etc.) to identify potential problems.
Process Variable Monitoring: Monitor process variables such as temperature, pressure, and speed to ensure these parameters remain within safe ranges.
Data Analysis and Reporting: Provide data recording and analysis functions, support the generation of detailed health status reports, and facilitate predictive maintenance.
Remote Access: Support remote monitoring and diagnosis, making it convenient for technicians to keep abreast of equipment status and take measures even when they are not on site.
Alarm Settings: Multiple alarm levels can be configured to notify operators immediately once an abnormal situation is detected.
