| Abstract: | Novel ceramic capacitive pressure sensors(CCPS) are researched by the thick film sensitive technology.The preparation technique and hybrid integration of the pressure sensitive component are emphasized.The basic principle,fabric design,manufacturing technique and performance test of dualcapacity pressure sensitive component are described in detail.Experimental results indicate that the component has excellent performance,the non-linearity error and hysteresis error are within 1.0 % and 0.5 % respectively,especially,both temperature coefficient of capacity(TCC) are identical. |
