气压放大器的新结构设计

A New Structure Design of the Barometric Amplifier

分析了原气压放大器结构所存在的缺点，设计了一种新结构。并对其进行了静、动态特性分析。结果证明，新结构较原结构具有输入和输出线性化，放大倍数精度高，抗干扰性强，结构简单等特点。并改善了其生产制造工艺性，具有实际应用的潜力。

An analysis is given of the defaults existing in the original barometric amplifier′s structure and a new structure in this amplifier is designed in the paper, hereupon both static and dynamic features analyses are also described. The result shows that this new structure as compared with the original one is characterized by linear output and linear input, high accuracy offered by amplifying times, strong resistance to interference, simple structure , etc. Its manufacturing technique is improved, too, which embodies high potentiality in practice.
