基于应变电阻效应，研制了压力范围为0~500兆帕的超高压传感器。它主要由弹性元件和敏感元件组成。该传感器的量程由弹性元件的结构和材料决定。为了承受超高压，选用弹性元件的材料作为弹簧钢，并对其结构进行了分析和模拟。之后，将作为敏感元件的金属应变片封装在弹性元件上。经过一定的补偿处理后，研制出了传感器。最后，对传感器进行了标定。结果表明，该传感器具有良好的性能，精度可达0.35%fS，满足航天、兵器等领域的要求。
Based on strain-resistance effect, an ultra-high pressure sensor has been developed with the range of 0-500 MPa. It is mainly composed of the elastic element and sensitive element. This sensor's range is determined by the elastic element's structure and material. In order to endure the ultra-high pressure, the elastic element's material is selected as spring steel, and its structures are analyzed and simulated. After that, the metal strain gauge as the sensitive element is packaged on the elastic element. Then the sensor is developed after some compensation processes are carried out. In the end, the sensor is calibrated. The results show that the sensor has good performance, such as the accuracy of 0.35%FS, which meets the requirements of aerospace, weapons and other fields.
