ДАВЛЕНИЯ СО СТАТИЧЕСКОЙ КОМПЕНСАЦИЕЙ в трубопроводе. Одновременно к чувствительным элементам 1 и 2 по соединительным трубкам 7 подвод тс  давлени  от мерных сечений Так как величина статического давлени  присут ствует как внутри упругих чувствительных элементов , так и снаружи, то их стенки испытывают только динамические составл ющие давлени . Изгиб балки, происход щий под действием суммы динамических составл ющих давлений, фиксируетс  тензорезисторами и преобразуетс  в электрический сигнал. Формула изобре тени  Устройство дл  измерени  перепада давлени  со статической компенсацией, содержащее )еренциальный датчик давлени , подключенный 8 4 соединительными трубками к мерным сечени м, отличающеес  тем, что, с целью. повыщени  точности измерени , оно снабжено камерой противодавлени  с водоводом дл  соединени  с исследуемым объектом, а дифференциальный датчик давлени  вьтолнен в виде двух чувствительных к давлению упругих элементов , соединенных встречно и св занных с балкой, на которой размещены тензорезисторы, и расположен в воздущной полости камеры противодавлени . Источники информации, прин тые во внимание при экспертизе 1.Авторское свидетельство СССР № 468120, кл. G 01 L 7/06, 12.07.73. PRESSURE WITH STATIC COMPENSATION in the pipeline. At the same time, pressure from the measured sections is supplied to the sensitive elements 1 and 2 by the connecting tubes 7. Since the static pressure is present both inside the elastic sensitive elements and outside, only the dynamic pressure components experience their walls. The bending of the beam, which occurs under the action of the sum of the dynamic component pressures, is fixed by the strain gauges and converted into an electrical signal. Formula invented shadows A device for measuring a differential pressure with static compensation, comprising) A pressure sensor connected by 8 4 connecting tubes to measuring sections, characterized in that, with a target. to increase measurement accuracy, it is equipped with a backpressure chamber with a water line to connect with the object under study, and the differential pressure sensor is implemented as two pressure-sensitive elastic elements connected counter-and connected to the beam on which the strain gages are located, and is located in the backpressure chamber of the counterpressure chamber .
