摘要: 零点温度输出是影响应变式传感器精度的主要性能指标，如果不加控制和补偿，很难达到0.02%FS/10℃的精度要求。明确传感器零点温度输出的主要影响因素，提出电路补偿法和算法软件补偿法。通过电路补偿法和算法软件补偿，可以将传感器精度提升至0.02%F.S/10℃，且算法软件补偿可获得更高精度。
Abstract: Zero temperature output is the main performance parameter of the strain sensor. If it is not con-trolled and compensated, the sensor accuracy is difficult to achieve 0.02% F.S per 10˚C. The main influencing factors of the zero temperature output of the sensor are defined, and the circuit com-pensation method and algorithm software compensation method are proposed. Through the compensation method, the sensor precision can be up to 0.02% F.S/10˚C, and the algorithm soft-ware compensation method can obtain higher precision.
