产品详情

直角弯头热电偶 WRN-530工业用装配式热电偶作为测量温度的传感器,通常和显示仪表、记录仪表和电子调节器配套使用。它可以直接测量各种生产过程中从0℃~1800℃范围内的液体、蒸汽和气体介质以及固体的表面温度。

根据国家规定,我厂从1987年起开始生产符合LEC***分度号的铂铑30-铂铑6、铂铑10-铂、镍铬-镍铬、镍铬-铜镍、铜-铜镍、铁-铜镍等形式热电偶,应符合JB/T9238-1999标准。

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。

WRN-130热电偶热电偶公称压力 

一般是指在室温情况下保护管所能承受的静态外压而不破裂。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。

热电偶最小置入深度  

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.对于长度超过1米的热电偶它的常温绝缘电阻值与其长度的乘积应不小于100.

即Rr.L≥100 MΩ。M L>1m

式中:Rr-热电偶的常温绝缘电阻值MΩ

b.对于长度等于或不足1米的热电偶,它的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现定:

上限温度tm℃试验温度t℃电阻值MΩ
100≤tm<300t=tm10
300≤tm<500t=tm2
500≤tm<850t=tm0.5
850≤tm<1000t=tm0.08
1000≤tm<1300t=tm0.02
