摘要

Improvements introduced in the object of the main patent No. 311.762, requested on April 13, 1965, by: "A procedure for the electrical measurement of the variation of a physical quantity transformed into a variation of length", characterized in that the voltage obtained as a measure for a first variable variable, it is interrupted at the rate of an impulse voltage, whose amplitude and pulse duration is constant, and whose frequency is proportional to a second variable variable, the interrupted DC voltage being integrated in a measuring instrument , and indicated as physical magnitude, which is equivalent to the product of the two variables mentioned.
