Abstract
Изобретение относитс к емкостным датчикам давлени и может быть использовано дл измерени статического и динамического давлений жидких и газообразных сред. Цель изобретени - увеличение точности измерени . Достигают это за счет того, что в датчике давлени , содержащем корпус 1, мембрану 2 и колпачок 4 с установленными на их поверхност х электродами измерительного и эталонного конденсаторов, в верхней части кол ачка устанавливаетс с нат гом диск-герморазъем 6, а по периферии дна колпачок жестко соединен с утол- щенным периферийным участком 3 мембраны 2. 3 ил.The invention relates to capacitive pressure sensors and can be used to measure the static and dynamic pressures of liquid and gaseous media. The purpose of the invention is to increase the measurement accuracy. This is achieved due to the fact that in the pressure sensor containing the housing 1, the membrane 2 and the cap 4 with the measuring and reference capacitor electrodes installed on their surfaces, in the upper part of the collar is mounted with a pressure-strain relief 6, and along the bottom periphery the cap is rigidly connected to the thickened peripheral section 3 of the membrane 2. 3 Il.
