WZ系列温度传感器元件
本公司提供生产的WZ系列热电阻严格按照*/T8622-1997技术要求生产，其分度号PT1000、PT500、PT200、PT100、PT10、CU50、CU100均*合国际标准。
热电阻的工作原理：在温度的作用下，电阻丝的电阻随之变化而变化。可用于测量-200℃～﹢800℃范围内的温度。其优点是：偏差*小。由于它的良好电输出性能，热电阻可为显示仪、记录仪、调节仪、扫描仪及电脑提供*的输入值。

2.热响应时间
在温度出现阶跃变化时,热电阻的电阻值变化至相当于该阶跃变化的50%，所需要的时间称为热响应时间，用t0.5表示。
3.自热影响
铂电阻允许通过电流1mA，*大测量电流为5mA，由此产生的升温不大于0.3℃。
4.电阻温度系数（α）与标称值的偏差

5.*缘电阻
当周围空气温度15-35℃和相对湿度小于80%时热电阻*缘电阻不小于100MΩ。
WZC系列元件
WZC型铜电阻是用*度聚酯*缘铜丝拴绕在棒形塑料或胶木骨架上。为*铜丝松散以及**缘性和机械强度，整个元件经过酚醛树脂浸渍处理。
