Microcomputer Based Wide Range Digital Tachometer
Digital tachometer is one of the electronic instruments that are very frequently used in industry. In this paper an overview of the most frequently used methods for the angular speed measurement is presented and the concrete realization of an instrument which works according to method of the constant elapsed time is presented. This is one upgraded realization of digital tachometer which offers additional features. Microcomputer system enables the connection of this instrument with a personal computer, which makes the tachometer an intelligent measurement module. Using LabVIEW software, realized module is very easy modifying to virtual instrument with high performance. Ill. 8, bibl. 7 (in English; summaries in English, Russian and Lithuanian).
