Recently, a transient resistant to ultra-high temperature 2000 ℃ isolate the impact of high temperature silicon pressure sensor in the Institute of Precision Engineering, Xi'an Jiaotong University successfully developed。

Experts believe that this national "863" project completed, will effectively solve the aerospace, petrochemical, automotive and other fields under high temperature high temperature and pressure measurements and instantaneous impact of the technical problems of sensor failure, breaking the similar foreign products on the the monopoly of the sensor market, enhance the overall level of the industry and international competitiveness, promotion and use of high value。

According to reports, the conventional silicon pressure sensor can only measure the pressure below 120 ℃ for more than 120 ℃, a serious deterioration in the performance of the sensor as well as failure. Conventional measurement methods and means can not meet the harsh environment of high temperature pressure measurement and automation requirements of increasingly high accuracy, resulting in a long time of high temperature pressure sensor products rely mainly on imports. Xi'an Jiaotong University developed the high temperature pressure sensor in -30 ℃ ~ 250 ℃ under the pressure measurement, to be completed by 1000Mpa any of the following range of pressure measurement range, can withstand high temperature 2000 ℃ instantaneous impact. To meet the high temperature, high pressure, high frequency response and transient heat shock pressure measurement in harsh environments, with independent intellectual property rights, to fill the many gaps in this field, our instruments for promoting industrial development, develop new economic growth is important。
