把电学量传感器测量物理量的范围,平分二段,分别建立拟合回归方程,并用电路实现之。这种线性处理方法具有通用性。以K型热电偶传感器为实验例子,未经线性处理前,理论线性度为3. 2 % ,线性处理后,理论线性度为0. 015 %。测量数据标准差为0. 001 38。关键词: 传感器; 回归方程; 线性处理Abstract : The measuring range of electric quantity sensor is divided into two parts ,the regressive equations are respectively set up and realized it using circuits.
