铂热电阻Pt100桥式温度变送器电路的传递函数
资料介绍
用铂热电阻Pt100测量介质温度,是温度采集和自动控制系统中普遍采用的方式。由于铂热电阻温度传感器在实际应用中存在电阻与温度间的非线性关系,为进一步提高温度测量的准确性,提出一种利用计算机非线性修正技术实现Pt100桥式温度变送器电路传递函数的方法。
Measuring medium temperature by platinum resistance Pt100 is a method commonly adopted in temper- ature collection and auto-control system. Because of existence of the nonlinear relationship between resistance in the actual application of platinum resistance temperature sensors, to further enhance the accuracy of the tempera- ture measurement, this paper proposes the method of using computer nonlinear correction technology to realize the transfer function of Pt100 bridge type temperature transmitter circuit.
