Abstract
In order to suit for the special requirements of the oil and gas fields, in this paper, the design and fabrication of a high-temperature and high-pressure sensor chip was described. And the related high-performance digital transmitter system was produced. The textual sensor chip was designed to accomplish the thermostability in the high temperature environment which the traditional sensor can't suit for. The linearity and accuracy of the system were promoted by the digital compensation technology. And the associated equipment were integrated into the system. Moreover, in order to meet the requirements of the oil and gas fields inspect managements, the wireless sensor network were designed, which can guarantee the high-efficiency operation and control of the industrial production. Through the experiments, the high-accuracy and reliable of the high-performance micro sensor and digital transmitter system were credible. The accuracy of it is above 0.2 % FS. The system has reached the world class and was especially significant for the domestic petrochemical industry.
