A low power vibration sensor and wireless transmitter system has one or
more sensors that sense parameters of a machine including vibration and
produces dynamic signals representing the sensed parameters. The system
converts the signals to a digital format, digitally filters the signals,
and processes the signals. A processor determines a plurality of levels,
which represent the characteristics of the signal such as the peak value
of a predetermined set of data points of the digital signal. Together,
the levels comprise a PeakVue waveform. The processor determines the peak
level value for the PeakVue waveform. Also, a true root-mean-square is
calculated as the signal is received at the processor. The peak level and
the RMS value are communicated wirelessly by a communication module to a
control protocol network such as a daisy chain HART or Fieldbus protocol
network. The system power supply and the communication module power
supply are separate and allow for low power operation.
