镍硅热电偶/WRN-230/WRN230 □ 主要技术指标 ● 温度测量范围和允许误差 | 热电偶类别 | 代号 | 分度号 | 测温范围 ℃ | 允许误差Δt ℃ | | 铂铑30-铂铑6 | WRR | B | 0～1800 | ±1.5℃或±0.25%t | | 铂铑10-铂 | WRP | S | 0～1600 | ±1.5℃或±0.25%t | | 镍铬-镍硅 | WRN | K | 0～1300 | ±2.5℃或±0.75%t | | 镍铬-铜镍 | WRE | E | 0～800 | ±2.5℃或±0.75%t | ● 热响应时间 在温度出现阶跃变化时，热电偶的输出变化至相当于该变化的50%，所需要的时间称为热响应时间，用T0.5表示。 ● 热电偶公称压力 一般是指在室温情况下保护管所能承受的静态外压面不破裂。实际上，容许工作压力不仅与保护管材料、直径壁厚有关，还与其结构形式，安装方法、置入深度以及被测介质的流速和种类等有关。 ● 热电偶zui小置入深度 应不小于其保护管外径的8~10倍（特殊产品例外）。 ● 热电偶绝缘电阻（常温） 常温绝缘电阻的试验电压为直流500V±50V，测量常温绝缘电阻的大气条件为温度15~35℃，相对湿度45%，大气压力86~106kPa a.对于长度＞1米的热电偶，常温绝缘电阻值与其长度的乘积应不小于 100 MΩ·m 即：Rr·L≥100 MΩ·m L＞1m（式中：L-热电偶的长度.m） b.对于长度≤1米的热电偶，常温绝缘电阻值应不小于100 MΩ ● 上限温度绝缘电阻 热电偶的上限温度绝缘电阻应不小于下表规定： | 上限温度tm ℃ | 试验温度t ℃ | 电阻值 | | 100≤tm＜300 | t=tm | 10 | | 300≤tm＜500 | t=tm | 2 | | 500≤tm＜850 | t=tm | 0.5 | | 850≤tm＜1000 | t=tm | 0.08 | | 1000≤tm＜1300 | t=tm | 0.02 | |
