铁-铜镍j型热电偶又称铁-康铜热电偶 正极(jp)的名义化学成分为纯铁。 负极(JN)为铜镍合金。 测量温区为-200~1200℃,但通常使用的温度范围为0~750℃ 。
RISC-V指令集讲解(5)条件和无条件跳转指令 - 知乎
JAL指令是用 J-type 格式 (JAL是RV32I中唯一J-type的指令)。 JAL的指令格式为 JAL rd,offset。 x [rd] = pc+4; pc += sext (offset) 其机器码格式如图1所示。 其opcode为110_1111。 该指令把下一条指令的地址 (PC + 4)存入rd寄存器中,然后把PC设置为当前值加上符号位扩展的偏移量。 图1 JAL机器编码格式 [1] 注意偏移量是带符号扩展的。
Type J Thermocouple
Type J Thermocouple: The type J is also very common. It has a smaller temperature range and a shorter lifespan at higher temperatures than the Type K. It is equivalent to the Type K in terms of expense and reliability. Type J Temperature Range: Thermocouple grade wire, -346 to 1,400F (-210 to 760C) Extension wire, 32 to 392F (0 to 200C)
J Type Vs. K Type Thermocouple: The Difference Explained
2022年9月14日 · The J Type thermocouple is a general-purpose thermocouple with a smaller temperature range. It is most suitable for light industry operations where temperatures range between -346F to 2193F or -210C to 1200C. The J Type thermocouple is made of iron on the live positive leg and copper-nickel alloy on the neutral leg.

2024年1月10日 · Comprising iron & constantan alloys, the type j thermocouple range offers a range of j type thermocouple (-210°C to 1200°C). Their cost-effectiveness and versatility make them suitable for various industrial & household applications.
热电偶K型跟J型有什么分别? - 百度知道
j型热电偶具有线性度好,热电动势较大,灵敏度较高,稳定性和均匀性较好,价格便宜等优点,广为用户所采用。 j型热电偶可用于真空,氧化,还原和惰性气氛中,但正极铁在高温下氧化较快,故使用温度受到限制,也不能直接无保护地在高温下用于硫化气氛中。
補償導線 J-TYPE - 日進電線股份有限公司2025
鐵氟龍、矽膠及玻璃纖維材質通過UL VW-1垂直燃燒測試以及多項IEC測試,證實為低煙、無鹵、耐燃之產品。 J-Type適合於-210°C~+350°C溫域中使用,熱電動勢特性僅次於E-Type。 缺點則是在於因使用純鐵導體的緣故,在含有水分的氧化氣體中容易導致導體生鏽,於使用時須特別注意。 鐵氟龍、矽膠及玻璃纖維材質通過UL VW-1垂直燃燒測試以及多項IEC測試,證實為低煙、無鹵、 …
Thermocouple Types: Type J, Type K, Type N, Type T, Type E, Type …
The type J thermocouple is suitable for vacuum, reducing, or inert atmospheres, oxidizing atmosphere with reduced life. Iron oxidizes rapidly above 538 °C [1000 °F], so only heavy gauge wire is recommended for high temperature applications.
