Multi-functional bearing vibration measuring instrument is the latest intelligent bearing vibration measuring instrument we developed. The system uses computer and digital signal processing technology; synthetically assess the signals tested in the time domain and frequency domain. The measurement results are in line with the bearing vibration assessment on related national technical criteria and are helpful to diagnose the quality of the measured bearing. Virtual instrument language was used in the software system. It analyzes and deals with all kinds of complicated parameters according to the requirements. And one instrument can provide vibration velocity and acceleration measurements at the same time. It has friendly interface, intuitive display, simple operation, high reliability and scalability features, and data can be stored and printed. This instrument is applicable to vibration detection abnormal sound detection and fault diagnosis (spectral analyzes the vibration signals, Identify bearing fault location according to characteristic frequency of bearing parts, in order to control bearing quality) of deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings and tapered roller bearings.
　　 The instrument is applicable to measuring room of bearing factory and the measurment of bearing vibration on field of production, analysis and research on bearing manufacturing process, as well as the acceptance of bearing vibration performance.
