Abstract

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

Изобретение относится к измерительной технике и может быть использовано в химической, нефтедобывающей, целлюлозной и других промышленностях для измерений давлений в высокотемпературных средах. Существо изобретения заключается в том, что тензометрический датчик давления снабжается специальным капилляром, заполненным ртутью, через который исследуемое давление высокотемпературной среды воздействует на мембрану датчика. Датчик снабжен специальным функциональным преобразователем с двумя термоприемниками, вырабатывающими напряжения, которые, складываясь в необходимой пропорции с выходными сигналами датчика, позволяют реализовать инвариантный к температуре алгоритм работы измерителя давления.The invention relates to measuring equipment and can be used in chemical, oil, pulp and other industries for measuring pressure in high-temperature environments. The essence of the invention lies in the fact that the strain gauge pressure sensor is equipped with a special capillary filled with mercury, through which the investigated pressure of the high-temperature medium acts on the membrane of the sensor. The sensor is equipped with a special functional converter with two thermal detectors that generate voltages, which, combined in the necessary proportion with the output signals of the sensor, make it possible to implement a temperature-invariant algorithm for operating the pressure meter.
