传感器是新技术革命和信息社会的重要技术基础,是现代科技的开路先锋。从世界范围看,压力传感器主要有以下几个发展方向:第一,光纤压力传感器。这种敏感元件已被应用于临床医学,用来测量扩张冠状动脉导管气球内的压力。第二,电容式真空压力传感器。E+H公司的电容式压力传感器是由一块基片和厚度为0.8~2.8 mm的氧化铝(Al2O3)构成,其间用一个自熔焊接圆环钎焊在一起。该环具有隔离作
Sensor is an important technological basis for the new technological revolution and the information society. It is the pioneer of modern science and technology. From a global perspective, the pressure sensor has the following main directions: First, the optical fiber pressure sensor. This sensitive element has been used in clinical medicine to measure the pressure in the dilated coronary catheter balloon. Second, the capacitive vacuum pressure sensor. E + H’s capacitive pressure sensor consists of a substrate and aluminum oxide (Al2O3) with a thickness of 0.8 to 2.8 mm, brazed together with a self-welding torus. The ring has isolation
