Strain Based Systems and Methods for Performance Measurement and/or Malfunction Detection of Rotating Machinery

摘要

Performance measurement and/or malfunction detection of rotating machinery can be accomplished by using one or more strain measuring devices attached to a journal bearing housing, using the strain measuring device or devices to generate an electrically measurable output in response to a change of a force in at least part of the journal bearing housing, using a Wheatstone bridge circuit to convert the electrically measurable output to an analog electrical signal, converting the analog electrical signal to a digital electrical signal and analyzing the digital electrical signal to determine the performance of the machinery and/or existence of a malfunction in the rotating machinery.
