5、成，它们的一端T1是相互焊接的，形成热电偶的测量端T1(也称工作端)。将它插入待测温度的介质中；而热电偶的另一端T0(参比端或自由端)则与显示仪表相连，假设热电偶的测量端与参比端存在温度差，则显示仪表将指出热电偶产生的热电动势。热电偶的热电动势随着测量端温度的上升而增大，它的大小只与热电偶的材料和热电偶两端的温度有关，而与热电级的长度、直径无关。Thermocouple isbasedonphysical phenomenonthattwoconductorofdifferent materials is connected to form return circuit, when tempe

6、rature on both contact is different, it results in thermoelectric potential in return circuit.2.2 热电阻工作原理 Operation Theory of Thermal Resistance热电阻是利用金属导体或半导体有温度变化时本身电阻也随着发生变化的特性来测量温度的，热电阻的受热局部(感温元件)是用细金属丝均匀地绕在绝缘材料作成的骨架上，当被测介质有温度梯度时，则所测得的温度是感温元件所在范围内介质层的平均温度。制造热电阻的材料应具有以下特点：大的温度系数，大的电阻率，稳定的化学物理性能和良好

7、的复现性等。在现有的各种纯金属中，铂、铜和镍是制造热电阻的最适宜的材料。其中铂因具有易于提纯，在氧化性介质中具有高的稳定性以及良好的复现性等显著的优点，而成为制造热电阻的抱负材料。It is based on that temperature change of material results in change of its resistance.
