 1、热电偶元件: 它是由金属套管,绝缘材料(一般为氧化镁粉)和热电偶线三者组合而成的坚实体。按测量端的结构形式,一般可分为绝缘K型热电偶、接壳K型热电偶、露端K型热电偶和分离式绝缘型K型热电偶供用户选用,如果用户没有指明测量端的结构形式,则提供绝缘型或接壳形。
 2、安装固定装置,其结构形式可分为: 无固定装置K型热电偶,固定卡套螺纹K型热电偶、可动卡套螺纹K型热电偶,固定卡套法兰K型热电偶,可动卡套法兰K型热电偶和外保护管式K型热电偶等。
百家乐官网  3、接线方式: 其结构可分为,瓷接线板K型热电偶、简易式K型热电偶,同径保护帽式,防溅接钱盒式K型热电偶、防水接线盒式K型热电偶、隔爆接线盒式K型热电偶、插座式K型热电偶、弹簧压着式K型热电偶、手柄式K型热电偶、带补偿导线K型热电偶等。

K型热电偶的优点

1、测温范围大: 本系列铠装热电偶规格范围大,品种规格齐全适用于各种测量组合,在-200℃~+1600℃温度范围内均能使用。
2、反应速度快: 与装配式热电偶相比,因为外径小热容量少,故微小的温度变化也能迅速反应,尤其是微细铠装热电偶更为明显。
3、安装使用方便: K型热电偶材料可在其外径5倍的圆柱体上绕5圈并可在多处位置弯曲。
4、使用寿命长: K型热电偶易引起热电势恶化,断线等事故,而WR□K系列铠装K型热电偶用氧化镁绝缘,气密性好、致密性好、致密度高,寿命长。
5、机械强度,耐压性能好: 在有强烈震动,低温,高温,腐蚀性等恶劣条件下均能安全使用。K型热电偶最高可承受3*103Kpa/cm2的压力。
6、K型热电偶外径尺寸范围: 铠装热电偶外径可提供Φ2.5~8mm,特殊要求的可以提供Φ12mm的产品。
7、铠装热电偶的最大长度: 铠装热电偶的最大长度可达500m。
8、铠装热电偶芯数: 可提供单支芯(2芯),双支芯(4芯)和三支芯(6芯)的各类铠装热电偶。
9、装配热电偶装配简单,更换方便;
10、压簧式感温元件,抗振性能好;
11、K型热电偶测温范围大;
12、机械强度高,耐压性能好;
13、产品执行标准: IEC584 / IEC1515 / GB/T16839-1997 / JB/T5582-91
14、常温绝缘电阻: 热电偶在环境温度为20±15°C,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>1000Ω.m。
