This paper describes the research and design of a intelligent pressure transmitter with self-calibrated and nonlinear compensation function based on 16bit MCU MSP430. The system frame and Software flow chart of every part of the intelligent transmitter are supplied. The model of ∑-△ A/D converter is founded. The intelligent pressure transmitter accomplishes the functions of self-calibration and nonlinear compensation. The system is simulated by using Simulink on a computer. The intelligent pressure transmitter has been used in the industry control system and works well, which shows that the mode is accurate and the system is workable.
