Описывается измерительный комплекс контроля протечек. В отличие от принятого в практике органолептического подхода предлагается автоматическая обработка сигнала с последующим выводом о герметичности арматуры. В основу автоматической обработки положен алгоритм на основе анализа сингулярного спектра, обеспечивающего повышение чувствительности. Эффективность комплекса подтверждается результатами испытаний измерительного комплекса с использованием гидравлического стенда.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to the problem of identification of leakiness of pipeline fittings. A measuring system for leak monitoring is described. In contrast to the organoleptic approach adopted in practice, automatic signal processing is proposed, followed by a conclusion about the tightness of the valve. The automatic processing is based on an algorithm based on the analysis of the singular spectrum, which provides an increase in sensitivity. The effectiveness of the complex is confirmed by the test results of the measuring complex using a hydraulic stand.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>протечка арматуры</kwd><kwd>акустический сигнал</kwd><kwd>диапазон рабочих частот</kwd><kwd>анализ сингулярного спектра</kwd><kwd>проверка статистических гипотез</kwd><kwd>ошибки первого и второго рода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>valve leakage</kwd><kwd>acoustic signal</kwd><kwd>operating frequency range</kwd><kwd>singular spectrum analysis</kwd><kwd>statistical hypothesis testing</kwd><kwd>errors of the first and second kind</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">РД ЭО 1.1.2.01.0190-2010.
