What is the typical pressure in the pipeline where the gauge originates?
I think it was around 1 MPa.
The pressure of the instrument air supply is generally controlled at 600 kPa
Our unit keeps it at around 500 KPa.
We’re also around 500 kp, I guess
Speaking of the pipelines that are the origin of instruments, they have a long history. The original instruments were mostly pneumatic, using pneumatic signals for transmission. Later, electric instruments were developed, eliminating the need for gas conduits. These pneumatic instrument pipelines were initially used in mines to prevent gas explosions, and later applied in chemical plants. The pressure of the air supply source is generally 0.4 to 1 MPa, while the pressure of the pneumatic signal is 0.02 to 0.1 MPa, which corresponds to a current of 4 to 20 mA for analog signals. Has the original poster gained some basic understanding of the origins of instruments? Writing Chinese characters correctly isn’t that difficult, is it?
Design pressure: 1.0 MPa, operating pressure: 0.5–0.8 MPa
10 kilograms of pressure! ! ! !
The supply pressure for instrument air is generally 0.7–0.8 MPa(g)
