Directory of engineer Annotation << Back Research of Characteristics the Economical Converter of the Information Orlov A.V., Likontsev A.N., Yumagulov N.I. Considered economical transmitter of information (PI) is designed to work as a sensor in measuring generator set power ensures constant signal power impact on the test object and having a high metrological and operational parameters. Examined the impact of ratings on the circuit elements PI value of power input into an object of study. Examines the impact of ratings on the circuit elements PI value of the power input into the object of study. Noted that the change in voltage circuit PI temporary and relative performance has practically no effect, however, allows you to adjust the absolute values of the instantaneous and average power input into the object under study. Analyzed the infl uence of the electric resistance on the time and frequency parameters of the inverter information. With an aim the increase of stability of power of affecting signal the prospected object it is offered to break up the range of possible values of resistance of research object on subranges. Breaking up of range of resistances is recommended on subranges to carry out so that within the limits of the separately taken subrange constancy of the middle dispersed power was supported with an error there is no more set size. Keywords: transducer information; measuring a given power generator; ADC; DAC; resistance range; the object of study.
