熱響應時間 在溫度出現階躍變化時,熱電阻的輸出變化至相當于該階躍變化的50%所需要的時間,稱為熱響應時間,用t0.5表示。 公稱壓力 一般是指在常溫下,保護管所能承受靜態外壓而不破裂,試驗壓力一般采用公稱壓力的1.5倍。實際上,允許公稱壓力不僅與保護管材料、直徑、壁厚有關,而且還與其結構形式、安裝方式、置入深度以及被測介質的流速、種類有關。 熱電阻絕緣電阻: 常溫絕緣電阻的試驗電壓可取直流10~100V任意值,環境溫度應在15~35℃范圍內,相對濕度應不大于80%,常溫絕緣值應不小于100MΩ。 熱電阻允許通過電流 通過鉑電阻測量電流大不超過5mA。 WRN-4318, WRE-4318,,WN2-4318,WRE2-4318,WRN-43C, WRE-43C, WRN2-43C, WRE2-43C, WRR-120, WRR-121, WRR2-120, WRR2-121, WRP-120, WRP-121,WRP2-120,熱電偶WRP2-121, WRN-122, WRN-123, WRN2-123, WRR-130, WRR-131,WRR2-130,WRR2-131, WRP-130, WRP-131, WRP2-130, WRP2-131, WRN-133, WRN2-133,WRN-120,WRN2-120.
