  • Vibration of Valves and Piping - Control Global

    Vibration of Valves and Piping - Control Global

    29/12/2013· Vibration can be monitored by detecting the displacement it causes, the velocity (rate time) by which displacement occurs, or by accelerometers, which detect the rate at which this velocity changes. If the oscillation caused by vibration is detected by velocity, that oscillation has a phase shift relative to that of displacement, and acceleration has a phase shift relative to velocity (Figure 1).
