摘　　要：热偶型热敏电缆由热电极、隔离材料、保护管和冷端连接件组成,具有线性结构,是一种新型的线性温度传感器.它可以检测其沿线上存在的最高温度,并以直流电压信号输出.如果把它铺设在一个面(或空间)上,那么它测得的温度可以认为是该区域存在的最高温度.它是石化、核反应堆、仓储等领域大范围温度监测与过温报警的理想温度传感器.Thermocouple-type heat sensitive cable, a new linear temperature sensor, contains a continuous pair of dissimilar thermocouple conductors, a spacing material (insulation), an outer sheath and hermetically sealed cold end connectors. It is capable of detecting the maximum temperature existing along its entire length, and constantly generates a Millville signal proportional to the maximum temperature. This kind of sensor is properly suitable for measuring temperature or over-temperature alarm in a large field. It finds application in petrochemical processes, nuclear reactors, warehouses or granaries, engines, etc..
