What is I/F?
Thread Content
I don’t know if you have seen I/F in the PID flow chart. Recently, I saw this in the flow chart and was puzzled. I/P is easy to explain, electrical conversion, but I don’t know what this I/F means. I saw it at the air cooler. Another thing is that there is a P at the flow-limiting orifice plate. I don’t know what it means. Of course, this P is in an oblique square. Then I checked the relevant information and said that this P represents flushing. But what I don’t understand is that this orifice plate is in a hydrogen system. Why should this flushing function be added? I hope everyone can discuss the above issues.
input/feed back?
Is it current/frequency conversion? It’s frequency conversion control!
Same as 3L~~~~~~~~ current/frequency
I saw it on the variable frequency air cooling. I checked the instrument manual and didn't see it, which was frustrating. I just guessed it was the current and frequency, but I didn't know. What does the P on the orifice plate stand for? If it is flushing as the manual says, what does it do?
It is current/frequency conversion and frequency conversion control.
