Symbols for wireless network communication in petrochemical PID diagrams
Thread Content
Hello, experts! May I ask, how is the symbol for wireless network communication represented in petrochemical PID diagrams? For example, 5G and 4G network communications – if anyone who knows about this can give some advice, I’d appreciate it! !
In petrochemical PID (process flow and instrumentation diagrams), wireless network communication is usually represented by an antenna symbol. This symbol usually consists of a circular or oval base with three straight lines extending from it, similar to the icon used for ordinary broadcast or radio wave transmission. For specific 5G or 4G network communications, the symbols may be the same, but the specific technical standard (such as “5G” or “4G”) can be indicated next to the symbol to distinguish between different wireless technologies. In practice, the detailed definitions and symbols may vary slightly depending on the standards and specifications of a particular company; therefore, it is recommended to refer to the PID diagram drawing standards of the specific project or company. .
Please refer to HG/T 20505-2014 or SH/T 3101-2017.
I searched online; I’m not sure about this one, but it seems pretty similar to what I’m looking for
