注：“t”為感溫元件實(shí)測(cè)溫度，對(duì)于鉑電阻和銅電阻則為感溫元件實(shí)測(cè)溫度的值。

公稱壓力

一般是指在常溫下，保護(hù)管所能承受的靜態(tài)外壓而不破裂，試驗(yàn)壓力一般采用公稱壓力的1.5倍。實(shí)際上，允許工作壓力不僅與保護(hù)管材料、直徑、壁厚有關(guān)，而且還與其結(jié)構(gòu)形式、安裝方法、置入深度以及被測(cè)介質(zhì)的流速、種類有關(guān)。

熱電偶絕緣電阻：

常溫絕緣電阻的試驗(yàn)電壓為直流500V。測(cè)量常溫絕緣電阻的大氣條件為：溫度15～35℃，相對(duì)濕度45%，大氣壓力86～106Kpa。

對(duì)于長(zhǎng)度超過1米的熱電偶，它的常溫絕緣電阻值與其長(zhǎng)度的乘積不小于100兆歐·米，

即：Rr·L≥100MΩm L＞1m

式中：Rr-熱電偶的常溫絕緣電阻值，MΩ；

L-熱電偶的長(zhǎng)度，m。

對(duì)于長(zhǎng)度等于或不足1米的熱電偶，它的常溫絕緣電阻值應(yīng)不小于100 MΩ。

熱電阻絕緣電阻：

常溫絕緣電阻的試驗(yàn)電壓可取直流10～100V任意值，環(huán)境溫度應(yīng)在15～35℃范圍內(nèi)，相對(duì)濕度應(yīng)不大于80%，常溫絕緣電阻值應(yīng)不小于100 MΩ。
