In order to overcome the deficiencies of traditional pressure set, sots, a kind of intelligent pressure sensors with temperature cor-rection is designed. According to the intelligent sensor-system of com-position and range of applications, with fully taking into account the parameters the connection between of co-ordination, we chose a good usability, high reliability and low cost components com-posed of the retire measurement system, with controlling and dealing with in 80C51 microcontroler, 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 col-lected signal de-noising processing, crass-sensitivity of the decoupling and show the results. It also has a self-test, automatic temperature compensation and on-site communications and other functions.
