A brass tube about 15 inches long is coupled to the motor shaft at one end and through a bearing to a drum-typedial at the other. (Either method works equally well as the output frequency is controlled only by the prime mover rotational speed. The unit consists of a Pelton wheel mounted in a corrosion-resistant enclosure. This device is used for most cases as it is very simple in construction and highly accurate of all the types. Alternatively, you may find information on the manufacturer's website or in the documentation. It is important to note that the tachometer converts the velocity to a voltage; that voltage is then used as input in the negative terminal of the op–amp. 3 How Tach + Limiter work 6. As a result, the larger piston lifts up a 10 pound weight. Prewash, wash, and air dry 5. Other articles where Eddy-current tachometer is discussed: tachometer: The eddy-current, or drag, type is widely used in automobile speedometers; a magnet rotated with the shaft being measured produces eddy currents that are proportional to angular speed.
