● 熱響應(yīng)時間

在溫度出現(xiàn)階躍變化時，熱電偶的輸出變化至相當(dāng)于該變化的50%，所需要的時間稱為熱響應(yīng)時間，用T_0.5表示。

熱電偶感溫元件/WRE-002/WRE002● 熱電偶公稱壓力

　　一般是指在室溫情況下保護(hù)管所能承受的靜態(tài)外壓面不破裂。實際上，容許工作壓力不僅與保護(hù)管材料、直徑壁厚有關(guān)，還與其結(jié)構(gòu)形式，安裝方法、置入深度以及被測介質(zhì)的流速和種類等有關(guān)。

● 熱電偶zui小置入深度

　　應(yīng)不小于其保護(hù)管外徑的8~10倍（特殊產(chǎn)品例外）。

● 熱電偶絕緣電阻（常溫）

　　常溫絕緣電阻的試驗電壓為直流500V±50V，測量常溫絕緣電阻的大氣條件為溫度15~35℃，相對濕度45%，大氣壓力86~106kPa

　　a.對于長度＞1米的熱電偶，常溫絕緣電阻值與其長度的乘積應(yīng)不小于 100 MΩ·m

即：Rr·L≥100 MΩ·m L＞1m（式中：L-熱電偶的長度.m）

　　b.對于長度≤1米的熱電偶，常溫絕緣電阻值應(yīng)不小于100 MΩ

● 上限溫度絕緣電阻

　　熱電偶的上限溫度絕緣電阻應(yīng)不小于下表規(guī)定：

上限溫度tm ℃	試驗溫度t ℃	電阻值
100≤tm＜300	t=tm	10
300≤tm＜500	t=tm	2
500≤tm＜850	t=tm	0.5
850≤tm＜1000	t=tm	0.08
1000≤tm＜1300	t=tm	0.02
tm＞1300	t=1300	0.02
