It’s the latest in instrumentation for the well-appointed shop — an acoustically coupled fast Fourier transform tachometer. Sounds expensive, but it’s really just using a smartphone spectrum ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much in ...

Tachometers are typically attached to the output shaft of DC or AC inverter motors requiring close speed regulation. The tachometer feeds its signal to a control that adjusts its output to the DC ...

Tachometer generators (or tachogenerators) are electromechanical devices which output a voltage proportional to their shaft speed. They are used to power tachometers and to measure the speed of motors ...
