Can a radar level gauge with a 4...20 mA HART signal type be connected directly to a regular AI module?
It can be directly connected to a regular AI module. 4...20 mA HART is a common type of analog signal that can be received and processed using standard analog input (AI) modules. The HART protocol is a digital communication protocol that superimposes digital signals on 4...20 mA analog signals, providing additional process variable information and configuration functions. Therefore, by using a standard AI module that supports the HART protocol, it is possible to directly receive and decode 4...20 mA HART signals in order to obtain more information. .
It can be connected to regular AI cards as well as HART-type AI cards
It’s completely possible; HART communication does not affect the transmission of analog signals
I’ve created a technical exchange group. Do you want to join? There are already 200 members; if you want to join, add me on WeChat at gyqtbs008 and I’ll invite you in
It can’t be another ad group, right? {:2_30:}
No, there are manufacturers, but they hardly run any advertisements; it’s mainly a place for technical professionals to exchange information, and we need professionals like you to join the group and provide guidance
It basically involves pulling people into groups, which is similar to pyramid schemes
