Abstract:
1. A measurement instrument for communicating over a control protocol network, the control protocol network configured to transfer control protocol data in a control protocol to and from at least one gateway, the measurement instrument comprising: a sensor circuit for sensing a parameter of a machine and producing a dynamic signal based on the sensed parameter; an analog to digital converter for receiving the dynamic signal and for converting the dynamic signal to a digital signal having a plurality of data points; a digital filtering circuit for splitting the digital signal into a first filtered signal having a first frequency range bounded by a first lower frequency and a first upper frequency, and a second filtered signal having a second frequency range bounded by a second lower frequency and a second upper frequency, where the first lower frequency is less than the second lower frequency and the first upper frequency is less than the second upper frequency; a processor connected to receive the first filtered signal and the second filtered signal and configured for: a communication module for communicating the peak amplitude level data and the root-mean-square data over the control protocol network.
