FIELD: electric engineering. ^ SUBSTANCE: method includes generation of rectangular pulses, simultaneous generation of two temporal ranges, proportional to sizes of two measuring capacitors and changing in counter-phase, in accordance to physical value being measured. On completion of first time range it is determined, whether generation of second time interval is completed by that time, and if it is, signal is generated, characterizing reaching of given value by physical value being measured. Equality of two temporal ranges is maintained for given value of physical value being measured, while generation of pulses is performed independently on alterations of measuring capacitors. Device for realization of method includes generator of rectangular pulses, two resistors, connected by one clamps between each other, and by other clamps - to first plates of capacitors, second plates of which are connected to one another, D-trigger, inputs of which are connected to first plates of capacitors, and power amplifier. output of rectangular pulses generator is connected to outputs of resistors connected to each other, while output of power amplifier is the output of transformer. ^ EFFECT: increased speed of operation, increased resistance to interference. ^ 2 cl, 2 dwg |
