摘要
利用Matlab和Origin软件,从理论上分析了电压型非平衡电桥铂金属温度计设计中,各种参数对温度线性度的影响。设计了0~100℃范围的温度计,获得电桥的输出电压和测量温度具有很好的线性关系。
The influence ol a variety ol parameters on the linear ol the thermometer in the design ol the unbal-anced bridge are theoretically analyzed using Matlab software and Origin soltware.The thermometer was designed to obtain 0 ？100 trange.It was found that it has a good linear relationship between the output voltage of unbalanced bridge and temperature.
