1、应 用
通常和显示仪表、记录仪表、电子计算等配套使用。直接测量各种生产过程中的0°C~1300°C范围内液体、蒸汽和气体介质以及固体表面温度。
2、特 点
·装配简单,更换方便
·压簧式感温元件,抗振性能好;
·测温范围大
·机械强度高,耐压性能好
3、工作原理
热电偶的电极由两根不同导体材质组成。当测量端与参比端存在温差时,就会产生热电势,工作仪表便显示出热电势所对应的温度值。
4、主要技术参数
产品执行标准
IEC584
IEC1515
GB/T16839-1997
JB/T5582-91
5、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。
