The VibroLink WEND portable multi-channel fan vibration tester is a new generation of fan vibration testing professional instrument developed by MMF, a German company, based on the VDI3834 general guidelines. Its interface is not only more user-friendly than the previous VM30, but also simpler and faster in setting and selecting different measurement points. Zui is a testing system that can be extended to 12 channels, allowing operators to perform multi-point testing simultaneously, greatly improving testing reliability and efficiency. The fully Chinese operating system allows any non professional operator to independently complete testing tasks with only simple training. At present, the VibroLink WEND portable multi-channel wind turbine vibration tester has been recognized by many domestic wind power industry customers and third-party testing institutions, and has been widely used in this field.
