J型热电偶
A thermocouple is made up of of two dissimilar conductors in contact with one another, which produce a voltage when heated. Thermocouples are used as temperature sensors for measurement and control and can also be used to convert a temperature gradient into electricity.
这款 J型热电偶 (铁-铜镍合金)是一种常见、通用型热电偶,其温度范围为−40°C至+750 °C,灵敏度为55 µV/°C。电线颜色标准为白色(+)与红色(-)。
