Development Of Multi-functional Measuring Instrument For Rotating Speed

Speed measurement is very important in the industrial measurement. speedchanges in the size and operation of the machine is stable determines whether thedevice is normal operation, Therefore, the accurate measurement of the speed of greatsignificance to the protection of the normal operation of the high-speed rotatingmachinery.At present,certain error exists in measurement of rotating speed.Combiningwith the measuring method of multi-functional measuring instrument of rotatingspeed,the research and development procedures of multi-functional rotating speedinstrumeng are introduced. Compared with existing instrument, severalfunctions,e.g.,instant totating speed measurement,low totating speed measurement,counting, timing, linear velocity measurement,dual channel measurement,are addedwithout reducing of the technical indexes.The achievement of the project will displayexcellent social benefits in future rotating speed detection, and provide powerfultechnical guarantee to metrological administration department.In the development process of multi-functional speed meter, speed measurementmethod of speed measurement results, to find the reasons for the design of a variety ofmethods to improve measurement accuracy.The multi-functional speed measuring instrument is a fiber-optic speed sensor,independent research and the frequency of speed of acquisition and LabVIEW NI hasdeveloped a combination to form the measurement system. After measurement of thespeed of standard equipment, the experimental data to meet the design requirements.
