● 鎧裝熱電偶熱響應時間 在溫度出現階躍變化時,熱電偶的輸出值變化至相當于該階躍變化的某個規定百分數所需要的時間,稱為熱響應時間,用τ表示(取50%時用τ0.5表示)。 鎧裝熱電偶熱響應時間 | 熱響應時間τ0.5(秒) | 套管直徑d(mm) | 接殼式(≤) | 絕緣式(≤) | 2.0 | 0.4 | 0.5 | 3.0 | 0.6 | 1.2 | 4.0 | 0.8 | 2.5 | 5.0 | 1.2 | 4.0 | 6.0 | 2.0 | 6.0 | 8.0 | 4.0 | 8.0 |
● 絕緣電阻 當環境空氣溫度為20±15℃,相對濕度不大于80%時,絕緣型鎧裝熱電偶的熱電極與 外套管之間的絕緣電阻值應符合下表規定:
鎧裝偶直徑D(mm) | 試驗電壓DCV | 絕緣電阻MΩ·m | 0.25 | 50±5 | ≥100 | 0.5~1.5 | 50±5 | ≥1000 | ﹥1.5 | 500±50 | ≥1000 | 注: 絕緣電阻用MΩ· m表示,即為常溫絕緣電阻與鎧裝偶 長度的乘積。 例如:1000MΩ·m表示:1m長的試樣的絕緣電阻為 1000MΩ,10m長的試樣的絕緣電阻為100MΩ。 對于長度小于1m的鎧裝偶,按1m計算。 插座式接線盒和帶補償導線的鎧裝熱電偶不在此例。 | □鎧裝熱電偶基本結構 鎧裝熱電偶主要由接線盒、接線端子和鎧裝熱電偶元件等組成基本結構,并配以各種安裝固定裝置。 熱電偶: 裝配式不銹鋼接線盒熱電偶WRR-120B,WRR-121B,WRR2-120B,WRR2-121B,WRP-120B,WRP-121B,WRP2-120B,WRP2-121B,WRN-122B,WRN-123B,WRN2-123B,WRR-130B,WRR-131B,WRR2-130B,WRR2-131B,WRP-130B,WRP-131B,WRP2-130B,WRP2-131B,WRN-133B,WRN2-133B,WRN-130B,WRN2-130B,WRE-130B,WRE2-130B,WRN-230B,WRN2-230B,WRE-230B,表面熱電偶溫度計WRE2-230B,WRN-220B,WRN-220AB,WRN2-220B,WRN2-220AB,WRE-220B,WRE-220ABWRE2-220B,WRE2-220AB,WRN-230B,WRN2-230B,WRE-230B,WRE2-230B,WRN-330B,WRN2-330B,WRE-330B,WRE2-330B,WRN-430B,WRN2-430B,WRE-430B,WRE2-430B,WRN-420B,WRN-420AB,WRN2-420B,WRE-420B,WRE-420AB,WRE2-420B,WRN-430B,WRN2-430B,WRE-430B,WRE2-430B,WRN-530B,鎧裝熱電偶WRN2-530B,WRE-530B,WRE2-530B,WRN-631B,WRN2-6310B,WRE-631B,WRE2-631B,WRN-620, WRN-621B,WRN-620A, WRN-621AB,WRN2-620, WRN2-621B,WRE-621B,WRE-621AB,WRE2-621B,WRN-631B,WRN2-631B,WRE-631B,表面熱電偶WRE2-631B,WRN-624B,WRN-625B,WRE-624B,WRE-625B, WRN-420B,WRN-430B,WRN2-420B,WRN2-430B,WRE-420B,WRE-430B,WRE2-420B WRE2-430B,WRN-420C,WRN-430C,WRN2-420C,WRN2-430C,WRE-420C,WRE-430C WRE2-420C,WRE2-430C,WRN-420D,小接線盒鎧裝熱電偶WRN-430D,WRN2-420D,WRN2-430D,WRE-420D,WRE-430D,WRE2-420D,WRE2-430D,WZP-420B,WZP-421B,WZP -430B,WZP-431B,WZP2-420B,WZP2-421B,WZP2-430B,WZP2-431B,WZC-420B,WZC-430B,WZP -420C,WZP -421C,WZP -430C,高溫耐磨熱電偶WZP -431C,WZP2-420C,WZP2-421C,WZP2-430C,WZP2-431C,WZC-420C,WZC-430C,WZP -420D,WZP -421D,WZP -430D,WZP -431D,WZP2-420D,WZP2-421D,WZP2-430D,WZP2-431D,WZC-420D,WZC-430D,WRE-892M,WRE-891M,WRE-890M,WREK-101,WREK-121,WREK-131,WREK-181,WREK-187,WREK-191,WREK-102,WREK-122,WREK-132,鉑銠10-鉑二等標準熱電偶WREK-182,WREK-188,WREK-192,WREK2-121,WREK2-131,WREK2-122,WREK2-132,WRNK-101,WRNK-121,WRNK-131,WRNK-181,WRNK-187,WRNK-191,WRNK-102,WRNK-122,WRNK-132,WRNK-182,WRNK-188,WRNK-192,WRNK2-121,WRNK2-131,WRNK2-122,WRNK2-132,WRCK-101,WRCK-121,WRCK-131,WRCK-181,WRCK-187,吹氣型熱電偶WRCK-191,WRCK-102,WRCK-122,WRCK-132,WRCK-182,WRCK-188,WRCK-192,WRCK2-121,WRCK2-131,WRCK2-122,WRCK2-132,WREK-201,WREK-221,WREK-231,WREK-281,WREK-291,WREK-202,WREK-222,WREK-232,WREK-282,WREK-292,WREK2-221,WREK2-231,WREK2-222,WREK2-232,WRNK-201,WRNK-221,WRNK-231,WRNK-281,WRNK-291,WRNK-202,WRNK-222,WRNK-232,WRNK-282,WRNK-292,WRNK2-221,WRNK2-231,WRNK2-222,WRNK2-232,WRCK-201,WRCK-221,WRCK-231,拱頂熱電偶WRCK-281,WRCK-291,WRCK-202,WRCK-222,WRCK-232,WRCK-282,WRCK-292.WRCK2-221,WRCK2-231,WRCK2-222,WRCK2-232 WREK-301, WREK-321, WREK-331, WREK-381, WREK-387, WREK-391, WREK-302, WREK-322, WREK-332, WREK-382, WREK-388, WREK2-321, WREK2-331, WREK2-322 WREK2-332 ,WRNK-301,超臨界電站用熱電偶WRNK-321, WRNK-331, WRNK-391, WRNK-381, WRNK-387, WRNK-302, WRNK-322, WRNK-332, WRNK-392, WRNK-382, WRNK-388, WRNK2-321, WRNK2-331, WRNK2-322, WRNK2-332, WRCK-301, WRCK-321, WRCK-331, WRCK-391,WRCK-381, WRCK-387, WRCK-302, WRCK-322, WRCK-392, WRCK-382, WRCK-388,WRCK2-321,WRCK2-331,WRCK2-322,WRCK2-332,WREK-401,WREK-421,WREK-431,WREK-481, WREK-491, WREK-402, 電站測溫用熱電偶WREK-422, WREK-432, WREK-482, WREK-492WREK2-421, WREK2-431, WREK2-422, WREK2-432, WRNK-401, WRNK-421, WRNK-431,WRNK-481, WRNK-491, WRNK-402, WRNK-422, WRNK-432, WRNK-482, WRNK-492,WRNK2-421, WRNK2-431, WRNK2-422, WRNK2-432, WRCK-401, WRCK-421, WRCK-431,WRCK-491, WRCK-481, WRCK-402, WRCK-422, WRCK-432, WRCK-492, WRCK-482,WRCK2-421, WRCK2-431, WRCK2-422, 隔爆型、本安型熱電偶WRCK2-432, WREK-501, WREK-521, WREK-531,WREK-581, WREK-591, WREK-502, WREK-522, WREK-532, WREK-582, WREK-592.
