【应用】偏差在0.3℃的温度传感器助力燃气表温度测量

时间： 2018-03-06 来源：世强作者：蜡笔小芯

技术问答

PT100是TE的PTF产品系列中一款简单易用的温度传感器，它的主要工作原理是随着温度值的变化，阻值产生变化，主控MCU通过采集阻值变化，读取出周围环境温度值。

在燃气表的设计中，新的国家规定要求测量温度和压力值，燃气表上面温度值测试需要考虑两个因素：

1. 燃气表规定要求温度的采集误差值不超过0.6℃，在实际应用中来说，电阻式温度传感器的偏差一般会比较大，因为它与外围其他元件的参数有关—MCU的ADC采集精度&分压电阻的精度。

所以在温度传感器的选型时需要注意，如果整个系统需要选择选择+/-0.6℃偏差的方案，那么最好选择器件的偏差在0.3℃，极力推荐型号：PTFC101B1G0。

2. 在燃气表的设计中，PCB板面非常紧张，所以器件的体积需要越小越好。

而PT100的设计如上图，它的传感探头部分的体积只有2.0mmX2.3mm，相对于其他温度传感器方案来说，体积非常小。

PT100就介绍到这里，下面额外分享下PT100的阻抗—温度换算表：
