LabVIEW

An article focuses on the development, research and implementation of algorithmic, hard- and software devices for controlling and diagnosing complex dynamic industrial objects. In the course of the research, the industrial object was selected, its main technical characteristics were determined, its base units were examined, and the most vulnerable sites were identified. There were the heaters of the heating zones, which correspond to the infra-frequency processes, and the bearings of the rolling gear reducer, which correspond to the high-frequency processes.

 The error of method appears when measuring voltage by data acquisition (DAQ) devices because of neglecting their input parameters. The experimental determination of input parameters, such as the equivalent Thevenin input voltage and resistance, for 9 DAQ devices NI USB 6009 was carried out in this paper. Uncertainties for these parameters are given as well. The experimentally determined parameters compared with that given in the device documentation.
