工作原理 |
热电阻是利用物质在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。热电阻的受热部分(感温元件)是用细金属丝均匀地双绕在绝缘材料制成的骨架上,当被测介质中有温度梯度存在时,所测得的温度是感温元件所在范围内介质层中的平均温度. |
特 点 |
全国统一设计产品,接口尺寸通用,互换性好; |
采用装配式结构,零件分解性好,维修方便; |
更换易损件成本低; |
规格齐全,性能稳定可靠。 |
绝缘电阻 |
装配铂热电阻的常温绝缘电阻应不小于100MΩ |
装配铜热电阻的常温绝缘电阻应不小于50MΩ |
常温绝缘电阻的试验电压为10~100V DC。 |
自热影响:铂电阻允许通过的zui大电流为5mA,由此产生的温升不大于0.3℃。 |
热响应时间:在温度出现阶跃变化时,热电阻的输出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τ0.5表示。 |
热电阻时间常数 |
热惰性级别 | 时间常数(秒) | 热惰性级别 | 时间常数(秒) | Ⅰ | 90-180 | Ⅲ | 10-30 | Ⅱ | 30-90 | Ⅳ | 10 | |
|
热电阻的公称压力:一般是指在工作温度下保护管所能承受的静态外压而不破裂。 |
热电阻zui小插入深度:应不小于其保护套管外径的8-10倍。 |
绝缘电阻:当周围空气温度为15-35℃,相对湿度<80%时,绝缘电阻 20兆欧(电压100V) |
。具有防溅式接线盒的绝缘电阻应2兆欧(电压100V) |
热电阻感温元件在0℃ 时电阻值(R0)及其与在100℃ 时的电阻值(R100)比值: |
比值=R100/R |
分度号为Pt10、Pt100时;R100 /R0 =1.3850±0.001 |
分度号为Cu50、Cu100时;R100 /R0 =1.3850±0.0 |
