Abstract
A device for measuring a parameter indicative of a rotational speed of a component includes a wired or wireless input configured to receive a vibration signal from a vibration sensor, a boost filter configured to filter the vibration signal, based on a predetermined frequency range, into a sinusoidal signal and, a comparator configured to generate a pulse waveform signal from the sinusoidal signal in order to read the value of the parameter. Also a motor or pump controller including the device.
