HIGH-TEMPERATURE MEDIUM PRESSURE METER

摘要

FIELD: measurement technology, chemical, oil, cellulose and other industries. SUBSTANCE: strain-gauge pressure transducer is fitted with special capillary filled with mercury through which examined pressure of high-temperature medium acts on membrane of transducer. Transducer is provided with special functional converter with two thermoreceivers which generate voltage which being summed up with output signals in required proportion makes it possible to realize algorithm of operation of pressure meter invariant to temperature. EFFECT: expanded functional capabilities, increased operational reliability. 3 dwg
