FIELD: measurement technology. SUBSTANCE: invention refers to means measuring pressure of gaseous and liquid substances with the aid of elastically deformed elements used as sensitive elements. It can find use in metallurgy, oil processing, gas producing, chemical and other branches of industry. Measuring converter of pressure difference has base 1, flange 2, measuring membrane 3 attached over outer contour between base 1 and flange 2, strain-gauge module 8 which outer circuit carries strain-measuring layer 11, unit 5 to transmit movements of membrane under action of lever of strain-gauge module 8, leak-tight space 12 with separating liquid formed by outer circuit of strain-gauge module 8 with strain- measuring layer 11, sealed adapter connector 13 anchored in base 1 and soft elastic medium separator 13 sealed in base 1 and electron converter 19. Surfaces 17, 18 of case 1 and flange 2 facing measurement membrane 3 match membrane corrugations in shape and are positioned at some distance from surface of membrane 3. EFFECT: reduced error of measurement caused by changes of temperature and static pressure of controlled medium. 2 cl, 1 dwg |
