  • Analysis during some events revealed vibration
    spikes believed to be integration noise generated
    from the double integration process of the
    Velomitor acceleration signal into a displacement
    signal.
  • Transducer systems that employ double integration
    of signals are not recommended for this reason
    and it is recommended the station not use the
    absolute (double-integrated) signal for trip
    relay activation.
