压阻式压力传感器零点温漂补偿公式的推导

Deducing A Compensation Formula of the Piezoresistive Pressure Sensor's Temperature Drift on Zero Signal

导出一套压阻式压力传感器零点温漂的补偿公式.从电桥平衡出发,提出对电桥桥臂一串一并的十几种补偿方法归结为两种,从而简化了数学计算和补偿工作的繁杂性,并对导出的公式的使用方法,加以说明,理论和实验得到了较好的验证.

This article deduces a set of formulas about compensating the pressure sensor＇s temperature drift on zero singal.For the sake of the balance of the electric bridge,more than ten compensating methods to the bridge arms are induced into two——the series and parallel join respectively,and thus the research has simplified the calculation of maths and complexity of compensating work.Moreover,the usage of two formulas are introduced,and have been testified in both theories and experiments.
