PRESSURE CONVERTER WITH BROUGHT-OUT LEAK-TIGHT DIAPHRAGM AND CORRECTION CIRCUIT AND PROCESS MEASURING PRESSURE Russian patent published in 2000 - IPC

FIELD: pressure converters. SUBSTANCE: invention refers to pressure converters fitted with brought-out diaphragms to measure pressure in tested medium ( in medium of process ). Pressure converter includes pressure transducer placed in case. Brought- out diaphragm is connected with pressure transducer by means of capillary tube filled with liquid. Diaphragm is displaced along vertical relative to case of converter. Converter incorporates electron circuits that form its output signal as function of pressure signal and correct output signal of converter depending on relative vertical displacement of brought-out diaphragm. EFFECT: increased measurement precision thanks to correction of temperature effect of systems of brought-out diaphragm under occasions specific for each individual plant. 11 cl, 11 dwg
