A high-accuracy digital tachometer using an encoder as transducer. Using a sine wave encoder, a 18-bit DAC converter and low sampling times, high accuracy and precision can be reached. The setup of parameters and the diagnostics are both carried out digitally using a serial port and an included software. For high accuracy applications, we suggest using high-end encoders such as Heidenhain angular transducers. The possibility of setting a wide variety of proportional factors allows the measurement of very low rotation speeds, and this has made the device very suited for use on astronomical telescopes.
