Изобретение относитс к измерительной технике и может использоватьс дл контрол размеров движущихс крупногабаритных изделий сложного профил из электропроводных материалов.The invention relates to a measurement technique and can be used to control the dimensions of moving large-sized articles of a complex profile of electrically conductive materials.
Известен способ измерени линейных размеров издели из электропроводного материала, заключающийс в том, что на поверхность издели направл ют струю жидкости, измер ют ее расход и по расходу суд т о размере контролируемого издели .A known method for measuring the linear dimensions of an article from an electrically conductive material is that a stream of liquid is directed to the surface of the article, its flow is measured and the flow is judged on the size of the article under test.
Однако диапазон измерени таким способом не превышает нескольких миллиметров.However, the measuring range in this way does not exceed several millimeters.
Цель изобретени - расширение диапазона измерений линейных размеров изделий из электропроводного материала.The purpose of the invention is to expand the range of measurements of linear dimensions of products made of electrically conductive material.
Эта цель достигаетс тем, что на поверхность издели подают электропровод щую жидкость и измер ют электрическое сопротивление струи.This goal is achieved by providing an electrically conducting fluid to the surface of the product and measuring the electrical resistance of the jet.
Предлагаемый способ по сн етс чертежом.The proposed method is illustrated in the drawing.
По трубопроводу 1, выполненному, за исключением металлических участков 2, из электроизол ционного материала, направл ют электропровод щую жидкость 3 на контролируемую поверхность издели 4. Участки АВ и ВС струи жидкости включают в диагонали электрического моста. Регулиру напор жидкости , добиваютс невозмущенного течени свободной струи с максимальной скоростью, что обеспечивает минимальное утонение струи по ее длине и, следовательно, линейную зависимость электрического сопротивлени от длины свободной струи. По отклонению стрелки электроизмерительного прибора суд т о поперечном сечении контролируемого издели .Pipeline 1, made, with the exception of metal sections 2, made of electrically insulating material, sends electrically conductive liquid 3 to the controlled surface of product 4. Sections AB and BC include liquid diagonals in the electric bridge. By adjusting the pressure of the liquid, an unperturbed flow of the free jet is achieved at maximum speed, which ensures minimum jet thinning along its length and, consequently, a linear dependence of the electrical resistance on the free jet length. According to the deviation of the arrow of the electrical measuring instrument, the cross section of the tested product is judged.
