| Abstract: | On the basis of traditional tiny differential pressure transmitter, an intelligent transmitter based on HART communication protocol was designed. Firstly, the hardware used in the system were introduced. Secondly, the whole hardware structure of this system, communication and data acquisition program flow diagram were described. The partial circuit of hardware was present which realize fundamental function of HART protocol transmitter. |
