你知道吗热电偶和热电阻应该有足够的插入深度

发布日期:2019-09-06 00:00 来源:http://repwithme.com 点击:

在热电阻的根部两端各衔接两根导线的方式称为四线制,其中两根引线为热电阻提供恒定电流I,把R转换成电压信号U,再经过另两根引线把U引至二次仪表。可见这种引线方式可整个消弭引线的热电阻影响,重要用于高精度的温度检测。


防爆热电阻


1、为了使防腐热电阻立博体育平台的测量端与被测介质之间有充分的热交换,应合理选择测点位置,尽量避免在阀门,弯头及管道和设备的死角附近装设热电阻。

热电偶


(3)假如需要测量是烟道内烟气的温度,尽管烟道直径为4m,热电阻插入深度1m即可.(4)当测量原件插入深度超过1m时,防爆热电阻立博体育平台应尽可能垂直安装,或加装支撑架和保护套管。
