摘要：In order to overcome the deficiencies of traditional pressure sensors,a kind of intelligent pressure sensors with temperature correction is *** to the intelligent sensor system of composition and range of applications,with fully taking into account the parameters of the connection between components of co-ordination,we chose a good usability,high reliability and low cost components composed of the entire measurement system,with controlling and dealing with in 80C51 microcontroller,the system had the temperature and pressure parameters with automatic measurement,amplification,A/D conversion,the weak signal locked amplification,as well as Phase-Sensitive Detection(PSD),common-mode signal rejection,the collected signal de-noising processing,cross-sensitivity of the decoupling and show the *** also has a self-test,automatic temperature compensation and on-site communications and other functions.
