基于MSP430的差压流量变送器的研发

The research of differential pressure flow transmitter based on MSP 430

介绍了压差流量计的测量原理,以TI公司生产的MSP430F149单片机为核心的差压流量变送器的设计。变送器采用支持HART通信协议的HT2012作为通信芯片,并介绍了HART通信的软件设计。

The measure theory of differential pressure flow meter and the design of differential pressure flow transmitter based on MSP430F149 microcontroller -（ produced by TI ） is introduced. Communicate controller HT2012 which support HART protocol is used in the design of transmitter, the design of HART communicate software is introduced.
