| Abstract |
Background. The object of the research is measuring circuit parameter sensors. The subject of research are methods of reducing the additional error parameter conversion informative gauge of changes in influencing factors. The aim is to develop an algorithm and schematic solution parametric sensor measuring circuit converter based on a microprocessor with high metrological characteristics.
Materials and methods. For additional error correction of the measurement of changes in influencing factors proposed to use the phase separation of the channels, providing the additional information on the influencing factors.
Results. We formulate a method for determining the output of the measuring circuit, the proportional informative parameters of the parametric sensor transducer, which is applied to the working and supporting parametric converters connected to the input of the active converter, voltage, shifted relative to each other by a certain angle. In the following sampling device made active converter output voltage information processing and computation of the informative parameter for a particular algorithm with the microprocessor. For implementation of a computational algorithm is necessary to provide multiple sampling frequencies in excess compared with the frequency changes affecting factors.
Conclusions. The proposed method of converting information parameter parametric converter based on phase separation channel provides error correction for a non-ideal path conversion elements as well as temporary instability affecting factors.
