● 现场常用铠装热电偶(Ⅱ级)测温范围和准确度 分度号 | 测温范围(℃) | 允差(参考端为0℃) | K、N | -40~1100 | ±2.5℃或±0.0075∣t∣ | E | -40~800 | J | -40~750 | T | -40~350 | ±1.0℃或±0.0075∣t∣ | 注:"t"为被测温度;在同一栏中给出的两种允差值中,取数值大者。 |
● 铠装热电偶热响应时间 在温度出现阶跃变化时,热电偶的输出值变化至相当于该阶跃变化的某个规定百分数所需要的时间,称为热响应时间,用τ表示(取50%时用τ0.5表示)。
铠装热电偶热响应时间 | 热响应时间τ0.5(秒) | 套管直径d(mm) | 接壳式(≤) | 绝缘式(≤) | 2.0 | 0.4 | 0.5 | 3.0 | 0.6 | 1.2 | 4.0 | 0.8 | 2.5 | 5.0 | 1.2 | 4.0 | 6.0 | 2.0 | 6.0 | 8.0 | 4.0 | 8.0 |
● 绝缘电阻 当环境空气温度为20±15℃,相对湿度不大于80%时,绝缘型铠装热电偶的热电极与 外套管之间的绝缘电阻值应符合下表规定:
铠装偶直径D(mm) | 试验电压DCV | 绝缘电阻MΩ·m | 0.25 | 50±5 | ≥100 | 0.5~1.5 | 50±5 | ≥1000 | ﹥1.5 | 500±50 | ≥1000 | 注: 绝缘电阻用MΩ· m表示,即为常温绝缘电阻与铠装偶 长度的乘积。 例如:1000MΩ·m表示:1m长的试样的绝缘电阻为 1000MΩ,10m长的试样的绝缘电阻为100MΩ。 对于长度小于1m的铠装偶,按1m计算。 插座式接线盒和带补偿导线的铠装热电偶不在此例。 | □铠装热电偶基本结构 铠装热电偶主要由接线盒、接线端子和铠装热电偶元件等组成基本结构,并配以各种安装固定装置。
● 安装固定型式: 固定装置是供用户安装时使用。铠装热电偶有:无固定装置、固定卡套式,可动卡套式,固定法兰式,可动法兰式五种结构型式。固定卡套式只供一次性固定使用,可动卡套式可做多次固定使用。
