Overview

When there is a step change in temperature, the output of the WRN2-420 thermocouple changes to 50% of the change, and the required time is called the thermal response time, represented by T0.5. The nominal pressure of a thermocouple generally refers to the temperature in the room .....

Product Details

WRN2-420热电偶 WRN2-420热电偶热响应时间

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
