A spinning shaft or gear's once-per-turn or multiple-event-per-turn pulse known as a keyphasor signal can be used to detect timing precisely. As a result, shaft rotative speed and vector characteristics like 1X vibration amplitude and Phase can be measured by 3500 monitor modules and external diagnostic tools.
