<=": 9pt"><="隶书"><="3"><="#">铠装铂电阻作为一种温度传感器，它比装配式铂电阻直径小，易弯曲，适宜安装在管道狭窄和要求快速反应、微型化等特殊场合。其可对-℃温度范围内的气体、液体介质和固体表面进行自动检测，并且可直接用铜导线和二次仪表相连接使用，由于它具有良好的电输出特性，可为显示仪、记录仪、调节器、 扫描器、数据记录仪以及电脑提供精确的输入值。
　　铠装电阻外保护管采用不锈钢，内充满高密度氧化物质绝缘体，因此它具有很强的抗污染和优良的机械强度，适合安装在环境恶劣的场合。　铠装铂电阻通常由铠装铂热电阻感温元件、安装固定装置和接线装置等主要部件组成。<="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体"><="宋体" =": 9pt"><="2"><="2"><="2">特点<="2">
