摘要
介绍了差动变压器式压力传感器的工作原理、磁路设计及关键工艺。具有灵敏度高、分辨力大的特点 ,工作在 2 2 0℃条件下漂移极小 .介绍了差动变压器组件 (铁芯衔铁线圈 )的选用原则。
The principle, the design of magnetic circuit and the key technics of the differential transformer type pressure sensor were described. The sensor has the character of high sensitivity, high resolution. Working under 220℃, has little drift. The law of component adoption, the confirmation and verification of parameter were introduced.
