| Abstract: | After the analysis of the current products applied in pressure measurement and the related acquisitions,this paper proposes a method to meet the requirements of auto air-conditioning linear pressure measurement by eddy current response. The elastic element of the sensor which is separated and integrated,includes the target,coil and processing circuit,was designed. And its structure,technology and material were analyzed. What's more,the working status was simulated and analyzed by both theory calculation and... |
