The common way to measure such instantaneous velocity is to install a coding wheel or a rotary encoder on the shaft. Then the rate of pulse delivered by such device is directly proportional to the RPM speed during the last pulse interval. This type of measurement needs a specific conditioner(usually an external box) which transforms the pulses train in a continuous voltage proportional to the RPM. Such devices are expensive, lead to more cable, are oftenlimited to 2 probes and so on. But the main inconvenience is the phase error they introducedue to their internal response time.<br> | The common way to measure such instantaneous velocity is to install a coding wheel or a rotary encoder on the shaft.
