便携式压电检波器测试仪系统设计

Design of the Portable Piezoelectric Geophone Tester

从分析压电检波器工作原理出发,对检波器测试仪的测试原理和测试方法进行了详细介绍,利用密闭腔比较测量法设计了一种压电检波器测试仪,在设计便携式压电检波器测试仪时用声压计替换了传统对比测量法中的标准检波器。该系统操作简单,精度高,取得了良好的效果。

This thesis starts with the analysis of Piezoelectric Geophone principle,and introduces the geophone tester＇s principles and testing methods in details. A piezoelectric detector tester is designed by using the closed chamber comparison measurement method. In the design of a portable detector tester,a sound pressure meter is replaced with the standard detector. The Piezoelectric Geophone Tester system is easy to operate and has high precision.
