概述：产品名称：铂铑13-铂直径：0.5mm起计量单位：克执行标准：IEC适用范围：0-1400℃高温，测温精准，取代进口铂铑热电偶产品简介及特点：该种热电偶的正极为含铑的铂铑合金(RP)，负极为纯铂(RN)。同S型热电偶相比，它的热电电动势率大15%左右，其它性能几乎完全相同。该种热电偶在日本产业界，作为高温热电偶用得***多，但在1981年以前的日本工业技术标准(JIS)中铂铑合金的铑含量为12.8%，同现行的R型热电偶相比，在1550℃下，其热电动势约低100μV，这点请注意。在真空、还原或含金属蒸气的条件下使用，均要受到玷污。长期使用温度一般不应超过1400℃。***丝材每米理论重量克/米直径mmPtAuAgPtRh6PtRh10PtRh303151.7136.474.11145.2141.4124.52.9141.8127.569.26135.7132.1116.32.8132.1108.964.57126.6123.1108.42.7122.8110.560.03117.75114.5100.842.6114102.455.67109.1106.293.482.5105.394.7551.47100.998.1786.442.497.0787.3247.4392.9690.2378.662.389.1780.2143.5785.3983.173.162.281.5673.3639.8678.1176.0266.942.174.3266.8536.3271.1769.2660.98267.4260.6432.9564.5762.8455.331.960.8454.7329.7358.2656.749.921.854.6149.1126.6852.2950.8944.81.748.7143.8120.846.6545.3939.961.645.4138.8121.0841.3140.2135.961.537.9234.1118.8336.3235.3431.121.433.0429.7216.1431.6330.7927.111.328.4825.6313.9227.2826.5523.371.224.2821.8411.8623.2522.6219.921.120.3918.349.9719.5319.0116.73116.8615.168.2416.1415.713.830.913.6612.286.6713.0712.7511.20.810.789.75.2710.3310.068.850.78.267.434.047.917.686.780.66.075.462.965.826.654.980.54.223.82.064.033.923.450.42.712.431.322.582.532.210.31.521.370.741.451.421.240.20.6750.6070.330.650.630.550.10.1690.1520.080.160.160.140.090.1360.1230.080.1080.0970.070.0830.0750.060.0610.0550.050.0420.0380.040.0270.0240.030.0150.0140.020.00680.0061密度21.4619.310.4920.552017.61备注:超细***丝在工业上广泛的使用，这些工业对丝材的独特要求在于非常细的丝径（0.0185mm起）且其严格的物料特性是必要的。这些应用包括电阻测温仪和***气体探测器。丝材的规格可以定制以适合客户的要求，包括一些特微的如电阻和温度系数，真实电阻和抗拉要求。)
