硅压力传感器是目前应用范围最广、生产量最大的压力传感器。它的发展使电路设计越来越简单,使用更方便,价格更便宜。在航空、航天、汽车、石油、化工、化纤、化肥、制药诸工业中,压力是重要测量,控制参数。另外,利用测量压力间接测量其它物理参数的方法也很多,例如,大型贮液罐的液位、海洋的水深、飞机的飞行高度和飞行速度、 Silicon pressure sensor is the most widely used, the largest production pressure sensor. Its development makes the circuit design more simple, more convenient to use, cheaper prices. In aviation, aerospace, automotive, petroleum, chemical, chemical fiber, fertilizer, pharmaceutical industries, pressure is an important measurement and control parameters. In addition, there are many ways to indirectly measure other physical parameters by using the measured pressure, such as the liquid level in a large liquid storage tank, the depth of the ocean, the flight altitude of the aircraft and the flight speed,
