全陶瓷质电容式压力传感器系80年代末才出现的新产品,国内尚属空白,国外也仅有美、德两国生产。因此国外商人以极高的价格卖给我国,大大限制了该类传感器的应用,我国每年仅军工、石油化工等行业就需引进10万套。山东省硅酸盐研究设计院新研制的全陶瓷质电容式压力传感器,采用了无中介液干式设计,具有抗过载和抗冲击能力强(过压可达量程的数倍至数百倍,复原后测量精度毫无影响),温度漂
All-ceramic capacitive pressure sensor is only appeared in the late 1980s new products, the domestic is still blank, only the United States and abroad, the United States and Germany to produce. Therefore, foreign businessmen sell to our country at a very high price, greatly limiting the application of this type of sensor. In our country, only 10 million sets need to be imported into the military, petrochemical and other industries every year. Newly developed by Shandong Silicate Research & Design Institute, the all-ceramic capacitive pressure sensor adopts a dry-type design without intermediate liquid and has the advantages of anti-overload and shock resistance (overvoltage can reach several times to several hundreds of times over range, After the restoration of measurement accuracy has no effect), temperature drift
