Description

(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ДАВЛЕНИЯ(54) DEVICE FOR MEASURING PRESSURE

нием газа з манометра в магистраль 2. Поэтому состав газа а манометре не измен етс .the gas from the pressure gauge to line 2. Therefore, the composition of the gas in the pressure gauge does not change.

После измереим давлевн  клапан 3 отключает манометр от магистршга2 н подключает его к магистрали 5.After measuring the pressure valve 3 disconnects the manometer from master2 and connects it to the line 5.

Повытвнне точности н упрс пение npaofcct нзмеренн  достигаетс  за счет того, что в момент  змеренв  в манометре сохран етс  газ нзвествого состава, но которому проградунрован манометр.The accuracy and control of the npaofcct is measured by the fact that at the time of measurement the gas of the star composition is retained in the manometer, but to which the manometer is passed.

чюрмула изобретени invention invented

Устрс ство дл  измерени  давлени , содержащее манометр, например теплюлектркческий соеданенную с манометром посредством нзмерттельной магистрали нолость с измер емым давтA device for measuring pressure, containing a pressure gauge, for example a heat-electric connection with a pressure gauge via a dead-flow line, a pressure gauge

и вторичный , отличающеес : тем, что, с целью повышешш точност  и угфшценк  процесса взмерени , оно снабжено двухпожцион ным злектроаневмат ческ м клапаном, установ ленным в измерительную магистраль на входе в манометр, и дополнительной полоспю с газовой средсА известного сост ва, например с воздухом под давлением болышм, чем измер емое давление, пр чем клапан соединен одним вхЬдом с ао оепю с измер е14ым давлением, а другим с даноп втель  ( полостью. and secondary, characterized by the fact that, in order to improve the accuracy and measurement of the metering process, it is equipped with a two-station electrical valve installed in the measuring line at the entrance to the pressure gauge, and an additional polospyu with a gas medium of a known composition, for example, with air under pressure is greater than the measured pressure, then the valve is connected to one with the measured pressure, and the other to the Danop floor (cavity.
