摘要
电阻式传感器的核心部件——电阻应变计是目前最常用的应力分析的敏感元件.也常用于测量力、压力、扭矩和加速度等物理量.作者简要回顾了电阻应变计的发展历史,介绍了电阻应变计的结构、分类及现状,展望了电阻式传感器的前景.
The electric restance strain gage, the core elements of the electric resistance sensors is the sensitive elements most widely used at present in the analysis of strain and guite often in the measurement of such physical parameters as force, presure, torgue, acceleration, etc. The author briefly recalls the development history and present situation of the electric resistance strain gages, introduces the structure and types of the gages, as well as their prospects.
