【摘要】 在讨论了压力传感器非线性输出误差分布规律的基础上 ,提出了压力传感器输出的一种新的非线性补偿方法 ,介绍了误差修正即补偿因子中三个基本参量 (A、ω、 )的取值方法。通过对两个压力传感器实际输出数据的补偿 ,使其线性度分别由补偿前的 1 .89%、2 .0 6%降低为补偿后的 0 .69%、0 .3 3 %。更多还原

【Abstract】 On the basis of discussion of errir distribution of non linearity output of pressure sensors, this paper presents a new non linearity compensation method of pressure sensors. Also, it introduces the taking value method for three basic parameters (A、ω、φ) in error modification, i.e. compensation factors. Through the compensation of realistic output data of two pressure sensors, the non linearity degrees are reduced from 2.01% and 2.06% prior to the compensation to 0.69% and 0.33% posterior to the compensation respectively.更多还原
