标准范围

IEC 60584-3:2021热电偶温度测量需要使用测量仪器精确测量热电偶电路的电动势（以下简称EMF）。热电偶通过一对合适的电缆与仪器进行电气连接。IEC 60584-3:2021标准化了这些电缆。它规定了直接提供给工业过程用户的延伸和补偿电缆（不包括矿物绝缘延伸和补偿电缆）的识别和制造公差。这些公差是根据IEC 60584-1中的e.m.f.版本温度关系确定的。规定了用于工业过程控制的延长电缆和补偿电缆的要求。

IEC 60584-3:2021 It is necessary for thermocouple temperature measurement that the electro-motive force (abbreviated as e.m.f. hereafter) of the thermocouple circuit is precisely measured by a measuring instrument. A thermocouple is electrically connected to the instrument by a proper pair of electric cables. IEC 60584-3:2021 standardizes these cables. It specifies identification and manufacturing tolerances for extension and compensating cables (mineral insulated extension and compensating cables are not included) provided directly to users of industrial processes. These tolerances are determined with respect to the e.m.f. ver-sus temperature relationship of IEC 60584-1. The requirements for extension and compensating cables for use in industrial process control are specified.
