热电偶热电偶

铠装热电偶应用通常和显示仪表、记录仪表、电子计算机等配套使用。直接测量各种生产过程中的0℃~1300℃范围内液体、蒸汽和气体介质以及固体表面温度。热响应时间少，减小动态误差;可弯曲安装使用;测量范围大;机械强度高，耐压性能好;工作原理铠装热电偶的电极由两根不同导体材质组成。当测量端与参比端存在温差时，就会产生热电势，工作仪表便显示出热电势所对应的温度值。主要技术参数产品执行标准:IEC584GB/T18404-2001测温范围及允差常温绝缘电阻铠装偶在环境温度为20±15℃，相对湿度不大于80%，试验电压为500±50V（直流）电极与外套管之间的绝缘电阻≥1000MΩ。即1m长的试样的绝缘电阻为1000MΩ;10m长的试样的绝缘电阻为100MΩ;型号分度号允差等级III允差值测温范围℃允差值测温范围℃WRNKK±1.5℃-40~+375±2.5℃-40~+333±0.004ltl375~1000±0.0075ltl333~1200WRMKN±1.5℃-40~+375±2.5℃-40~+333±0.004ltl375~1000±0.0075ltl333~1200WREKE±1.5℃-40~+375±2.5℃-40~+333±0.004ltl375~800±0.0075ltl333~900WRFKJ±1.5℃-40~+375±2.5℃-40~+333±0.004ltl375~750±0.0075ltl333~750WRCKT±0.5℃-40~+125±1.0℃-40~+133±0.004ltl125~350±0.0075ltl133~350WRPKS±1.0℃0~+1100±1.5℃0~600±[0.003(t-1100)]1100~1600±0.0025ltl600~1600偶丝直径及材料偶丝形式单支式双支式套管直径Φ2,Φ3,Φ4,Φ5,Φ6,Φ8Φ3,Φ4,Φ5,Φ6,Φ8套管材质E、J、T1Cr18Ni9Ti1Cr18Ni9TiK、N1Cr18Ni9TiGH30301Cr18Ni9TiGH3030SGH3039GH3039特点1注：t为被测介质温度安装固定形式卡套螺纹卡套法兰扳手卡套代号和尺寸铠装偶外径Φ8,Φ6,Φ5Φ4,Φ3,Φ2MM16×1.5M12×1.5S2219DΦ60Φ50D0Φ42Φ36D1Φ24Φ20SΦ22Φ19d0Φ9Φ7测量端结构形式接线盒形式防喷式防水式圆接插式扁接插式2ANHUITIANKANG(GROUP)SHARESCO.,LTD.手柄式带补偿导线式铠装热电偶推荐使用温度品种套管材料外径(mm)使用温度(℃)长期使用短期使用镍铬－镍硅1Cr18Ni9Ti2.06007003.0,4.0,5.0,6.0,8.0800900GH30302.0,3.08009004.0,5.090010006.0,8.010001100镍铬硅－镍硅1Cr18Ni9Ti2.06007003.0,4.0,5.0,6.0,8.0800900GH30302.0,3.090010004.0,5.0100011006.0,8.011001200GH30392.0,3.0,4.0,100011005.0,6.0,8.011001200镍铬－铜镍1Cr18Ni9Ti2.0,5006003.0,4.0,5.06007006.0,8.0700800铁-铜镍1Cr18Ni9Ti2.04005003.0,4.0,5.0,5006006.0,8.0600750铜-铜镍1Cr18Ni9Ti2.0,3.0,4.0,5.02503006.0,8.0300350铂铑10-铂GH30392.0,3.0,4.0100011005.0,6.0,8.011001200附加装置形式焊接焊接包箍式(代号G)接触块式（代号M）注：选型时应注明R大小（即管壁或炉壁直径）3(GROUP)SHARESCO.,LTD.防水式铠装热电偶防喷式防喷式防喷式型号分度号测温范围℃保护管材质安装固定装置WRPK-131S0~1300GH3039无固定装置WRMK-131N0~1100GH30300~8001Cr18Ni9TiWRNK-131K0~1100GH30300~8001Cr18Ni9TiWREK-131E0~6001Cr18Ni9TiWRCK-131T0~350WRFK-131J0~500WRPK-231S0~1300GH3039固定卡套螺纹WRMK-231N0～1100GH30300～8001Cr18Ni9TiWRNK-231K0～1100GH30300～8001Cr18Ni9TiWREK-231E0~6001Cr18Ni9TiWRCK-231T0~350WRFK-231J0~500WRPK-331S0~1300GH3039可动卡套螺纹WRMK-331N0~1100GH30300~8001Cr18Ni9TiWRNK-331K0~1100GH30300~8001Cr18Ni9TiWREK-331E0~6001Cr18Ni9TiWRCK-331T0~350WRFK-331J0~5005型号分度号测温范围℃保护管材质安装固定装置WRPK-431S0~1300GH3039固定卡套法兰WRMK-431N0～1100GH30300～8001Cr18Ni9TiWRNK-431K0～1100GH30300～8001Cr18Ni9TiWREK-431E0~6001Cr18Ni9TiWRCK-431T0~350WRFK-431J0~500WRPK-531S0~1300GH3039可动卡套法兰WRMK-531N0~1100GH30300~8001Cr18Ni9TiWRNK-531K0~1100GH30300~8001Cr18Ni9TiWREK-531E0~6001Cr18Ni9TiWRCK-531T0~350WRFK-531J0~5001)型号221、321防护等级IP65，其他参数同231、331;2)热电偶I级按协议订货3)未注明测温范围及保护管材质，保护管材质一律视为1Cr18Ni9Ti;接线方式单支接线方法双支接线方法6ANHUITIANKANG(GROUP)SHARESCO.,LTD.圆接插式铠装热电偶圆接插式圆接插式圆接插式名称型号分度号测温范围℃安装固定装置铂铑10-铂WRPK-161WRPK2-161S0~1300无固定装置镍铬硅-镍硅WRMK-161WRMK2-161N0~1100镍铬-镍硅WRNK-161WRNK2-161K镍铬-铜镍WREK-161WREK2-161E0~600铜-铜镍WRCK-161WRCK2-161T0~350铁-铜镍WRFK-161WRFK2-161J0~500铂铑10-铂WRPK-261WRPK2-261S0~1300固定卡套螺纹镍铬硅-镍硅WRMK-261WRMK2-261N0~1100镍铬-镍硅WRNK-261WRNK2-261K镍铬-铜镍WREK-261WREK2-261E0~600铜-铜镍WRCK-261WRCK2-261T0~350铁-铜镍WRFK-261WRFK2-261J0~500铂铑10-铂WRPK-361WRPK2-361S0~1300可动卡套螺纹镍铬硅-镍硅WRMK-361WRMK2-361N0~1100镍铬-镍硅WRNK-361WRNK2-361K镍铬-铜镍WREK-361WREK2-361E0~600铜-铜镍WRCK-361WRCK2-361T0~350铁-铜镍WRFK-361WRFK2-361J0~5007名称型号分度号测温范围℃安装固定装置铂铑10-铂WRPK-461WRPK2-461S0~1300固定卡套法兰镍铬硅-镍硅WRMK-461WRMK2-461N0~1100镍铬-镍硅WRNK-461WRNK2-461K镍铬-铜镍WREK-461WREK2-461E0~600铜-铜镍WRCK-461WRCK2-461T0~350铁-铜镍WRFK-461WRFK2-461J0~500铂铑10-铂WRPK-561WRPK2-561S0~1300可动卡套法兰镍铬硅-镍硅WRMK-561WRMK2-561N0~1100镍铬-镍硅WRNK-561WRNK2-561K镍铬-铜镍WREK-561WREK2-561E0~600铜-铜镍WRCK-561WRCK2-561T0~350铁-铜镍WRFK-561WRFK2-561J0~5001)热电偶I级按协议订货；2)未注明测温范围及保护管材质，保护管材质一律视为1Cr18Ni9Ti;8ANHUITIANKANG(GROUP)SHARESCO.,LTD.扁接插式铠装热电偶扁接插式扁接插式扁接插式名称型号分度号测温范围℃安装固定装置铂铑10-铂WRPK-171WRPK2-171S0~1300无固定装置镍铬硅-镍硅WRMK-171WRMK2-171N0~1100镍铬-镍硅WRNK-171WRNK2-171K镍铬-铜镍WREK-171WREK2-171E0~600铜-铜镍WRCK-171WRCK2-171T0~350铁-铜镍WRFK-171WRFK2-171J0~500铂铑10-铂WRPK-271WRPK2-271S0~1300固定卡套螺纹镍铬硅-镍硅WRMK-271WRMK2-271N0~1100镍铬-镍硅WRNK-271WRNK2-271K镍铬-铜镍WREK-271WREK2-271E0~600铜-铜镍WRCK-271WRCK2-271T0~350铁-铜镍WRFK-271WRFK2-271J0~500铂铑10-铂WRPK-371WRPK2-371S0~1300可动卡套螺纹镍铬硅-镍硅WRMK-371WRMK2-371N0~1100镍铬-镍硅WRNK-371WRNK2-371K镍铬-铜镍WREK-371WREK2-371E0~600铜-铜镍WRCK-371WRCK2-371T0~350铁-铜镍WRFK-371WRFK2-371J0~5009名称型号分度号测温范围℃安装固定装置铂铑10-铂WRPK-471WRPK2-471S0~1300固定卡套法兰镍铬硅-镍硅WRMK-471WRMK2-471N0~1100镍铬-镍硅WRNK-471WRNK2-471K镍铬-铜镍WREK-471WREK2-471E0~600铜-铜镍WRCK-471WRCK2-471T0~350铁-铜镍WRFK-471WRFK2-471J0~500铂铑10-铂WRPK-571WRPK2-571S0~1300可动卡套法兰镍铬硅-镍硅WRMK-571WRMK2-571N0~1100镍铬-镍硅WRNK-571WRNK2-571K镍铬-铜镍WREK-571WREK2-571E0~600铜-铜镍WRCK-571WRCK2-571T0~350铁-铜镍WRFK-571WRFK2-571J0~5001)热电偶I级按协议订货；2)未注明测温范围及保护管材质，保护管材质一律视为1Cr18Ni9Ti;10ANHUITIANKANG(GROUP)SHARESCO.,LTD.补偿导线式191补偿导线式291391补偿导线式491591补偿导线式铠装热电偶型号分度号测温范围℃长度安装固定装置LL1WRPK-191S0~130010020030040050075010001500200030004000500075001000015000250005007501000150020003000400050007500100001
