According to the pressure testing requirements under high temperature and high pressure environment in oil and gas field, this paper introduced the design and development of a kind of high temperature high pressure sensor chip, and solved the problems of thermal stability of traditional piezoresistive sensors in special environment. The method of packaging SOI piezoresistive chip of high temperature resistance and glass plate in one through technology of anodic bonding under circumstance of vacuum, solved the problem of wide measurement range of pressure under high temperature circumstance. Meanwhile, insulating the medium under investigation from sensor chips by adopting corrugated diaphragm and high-temperature silicon oil as isolation materials, improved the adaptability of sensors.
