РАЗМЕРОВSIZES
триЧеской проницаемости заключенного в нем газаpermeability of gas enclosed in it
Предлагаемый способ осуществл етс следующим образом.The proposed method is carried out as follows.
На поверхность контролируемого издели через пневматичгеский чувствительный элемент , например камеру, у которой одна й,з стенок выпогошна в виде упругой мембраны и сопло, сообщенное с камерой, направ; ют поток газа и одновременно в газовой полости камеры возбуждают сверхвысокочастотные электрмагнитные колебани переменной частоты, мен частоту до наступлени резонанса, и по этой частоте суд т о размере контролируемого издели ,On the surface of the controlled product through a pneumatic sensing element, for example, a chamber in which one, three, walls emerge in the form of an elastic membrane and a nozzle connected with the chamber, directed; gas flow and simultaneously in the gas chamber cavity excite microwave oscillations of variable frequency, change the frequency before resonance, and by this frequency judge the size of the controlled product,
Собственна частота колебаний в каме ре зависит от давлени газа в ней, а оно определ етс зазором между соплом и кон тролируемым изделием. Таким образом, частота сверхвысокочастотных колебаний вл етс показателем линейного размера,The natural frequency of oscillations in the chamber depends on the pressure of the gas in it, and it is determined by the gap between the nozzle and the controlled product. Thus, the frequency of microwave oscillations is an indicator of the linear size,
С ростом давлени газа в камере растут диэлектрическа проницаемость газа и объем камеры, что приводит к резкому снижению собственной частоты электромагнитных колебаний и обеспечивает высокую чувстви- телъность предлагаемого способаWith an increase in the gas pressure in the chamber, the dielectric constant of the gas and the volume of the chamber increase, which leads to a sharp decrease in the natural frequency of electromagnetic oscillations and ensures a high sensitivity of the proposed method.
Частота резонанса фиксируетс с высокой точностью, что обеспечивает в конечном итоге высокую точность измерени линейного размераThe resonance frequency is recorded with high accuracy, which ultimately ensures high accuracy of linear dimension measurement.
