Abstract

Speed measurements are very important task according to the large use of
motors, generators and other rotating devices. Also for the high speed of
rotation other than speed is a function of many other variables such as
acceleration and speed etc….
This project helps to measure the speed of electrical machines which is
very difficult to be measured directly.
The computer is used to measure the speed in revolution per minute
(RPM) or revolution per second (RPS), very accurately by using a suitable
circuit which is formed from, sensor, special designed electronic circuit and
interface card (Hardware) with a built program (Software) to treat the data and
to give the measured speed in a digital system.
