Patent ID: 7424403

Claim:
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: determining one or more peak amplitude levels of the second filtered signal over the second frequency range and producing peak amplitude level data in the control protocol, the peak amplitude level data representing the one or more determined peak amplitude levels, integrating the first filtered signal over the first frequency range resulting in an integrated signal; and determining a root-mean-square value from the integrated signal and producing root-mean-square data in the control protocol, the root-mean-square data corresponding to the root-mean-square value; and a communication module for communicating the peak amplitude level data and the root-mean-square data over the control protocol network.
