摘要：在压力测量中，通常是根据测量要求来提出不同的物理测量方法，比如绝对压力、相对压力（表压）和差分压力的测量。然而对于差分压力的测量往往有许多不同的理解。本文就以硅压阻压力传感器AMS 5812作为例子来介绍有关各种压力测量的不同应用情况。同时对硅压阻芯体相关的结构和惠斯顿电桥信号放大作了介绍。

Abstract: In pressure sensor technology various physical measurement methods are adopted depending on the application requirements. These include the measurements of absolute pressure, relative pressure, and differential pressure. But there are many different understanding in how to measure the differential pressure. Taking the piezoresistive sensor AMS 5812 as an example, practical application of various pressure measurement methods are introduced in this paper. To elucidate further, the important terms relevant to silicon pressure sensing elements and how to amplify the signal from a Wheatstone bridge are described too. 
Keywords: differential pressure sensor; bidirectional differential pressure sensors
