| 摘 要： | 为了精确测量气温,可以用铂电阻(Pt100)作为温度传感器制作测温装置,但是铂电阻具有电阻与温度成非线性特性.从介绍铂电阻特性入手,在实践中提出了一种铂电阻传感器非线性信号转换成温度的精密算法,也就是软件查表法和平均法进行非线性误差粗、精两级校正.这种算法由硬件和软件两部分构成.硬件是以性能优越的A/D转换器为核心组成的具有自校准和系统校准功能的精密转换电路,软件由给出的主要源程序代码组成.

| Abstract: | In order to accurately measure the temperature,it can be taken platinum resistance(Pt100)as a sensor of temperature measurement device,but it brings about the temperature-resistance nonlinear characteristics.A unique precise algorithm for the conversion of platinum resistance nonlinear signals into air temperature is put forward by introducing platinum resistance characteristics,and it is also the software table look-up law and the method of average which carry out the two levels of error adjustments.The re... |
