Let’s talk about what specific things those are
Thread Content
I was just looking at the specifications and have some questions; everyone, please share your thoughts
Pneumatic instruments are rare these days; those that used to exist in the past
This standard either lacks some time for adjustment, or it has not been revised to reflect the current realities. 1 refers to pneumatic control valves, 2 refers to pneumatic panel-mounted instruments such as pneumatic controllers and three-pin recorders, and 3 refers to instruments such as pneumatic differential pressure and pressure transmitters. In the 1970s, pneumatic instruments were the main force behind the automation of chemical production.
These days, instruments rarely use pneumatic signals~~ So, pneumatic instruments basically no longer exist~~ What year was the standard version released? ~~
It is a standard for pneumatic instruments. Pneumatic instruments were widely used 30 years ago; nowadays, electric instruments are more common. The devices that consume a large amount of gas are pneumatic control valves.
I think this standard time isn’t that old either
The amount of instrument air required depends on where it is used; it isn’t necessarily for pneumatic valves alone, as it is also used in other applications. For example, the dried air delivered can be used for instrument air as well as in other suitable devices (pneumatic instruments, pneumatic valves, air for the dynamic/static sealing of equipment, vacuum pumps, protective gas, etc.). . . . Plan and design according to the specific usage amount. As a **standard is just a framework; use the latest one.
