  • Measuring Fluid Pressure (AREA)

Description

лостй корпуса 2 должно состажч ть 0,961 при диаметре корпуса 250 мм.The body of the body 2 should be 0.961 with a body diameter of 250 mm.

В предложенном датчике статического давлени  при изменении температуры нат жение мембран остаетс  посто нным, что позвол ет повысить точность измерений.In the proposed static pressure sensor, as the temperature changes, the tension of the membranes remains constant, which makes it possible to increase the measurement accuracy.

Claims (2)

1. Датчик статического давлени , содержащий закрепленный на державке корпус в виде сферической оболочки с отверсти ми, внутри которого помещены заполнитель и электромеханический преобразователь давлени , отличающийс  тем, что, с целью уменьщени  вли ни  изменени  температуры на результаты измерений, отверсти  в корпусе снабжены1. A static pressure sensor containing a spherical shell with holes mounted on the holder, inside of which a filler and an electromechanical pressure transducer are placed, characterized in that, in order to reduce the effect of temperature change on the measurement results, the holes in the housing are provided герметичпыми мембрапами, внутри корпуса установлен объемный термокомпенсатор, например , в виде сферы с вакуумированной полостью , а в качестве заполпител  использована жидкость.sealed membranes, a volumetric temperature compensator is installed inside the case, for example, in the form of a sphere with a vacuumized cavity, and liquid is used as a fill. 2. Датчик по п. 1, отличающийс  тем, что мембраны изготовлены из материала с тем же термическим коэффициентом расширени , что и у корпуса.2. The sensor according to claim 1, characterized in that the membranes are made of a material with the same thermal expansion coefficient as the body.
