摘要
针对解决电阻应变式传感器所组成的测力及称重应用系统中发生的常见偏载现象而定性介绍的一种加法电路的基础上[1],借助误差理论工具,依据法定设计标准(规范),以电桥电路的阻抗为分析参数,采用近似理论优化手段分别得出抗偏载电阻RG、可调电位器RW、增益控制电阻的公式表达式与函数值的取舍标准。
An additive curcuit was introduced in order to solve the problem of the common deviation in force and weighing system composed of resistance strain sensor.According to error theory tool,legal design standard and approximation theory optimization method,the formula of deviation resistance RG,adjustable potential device RW and control resistance and the rejection standard of functional results were obtained.
