摘要： An improved self-regulating pipe heating cable assembly that includes a self-regulating cable having a temperature-sensitive conducting layer between a pair of busses and a plug coupled to a first end of the self-regulating cable for supplying electricity thereto. The improved self-regulating pipe heating cable assembly includes an indicator coupled to the self-regulating cable at a location other than where the plug is connected. The indicator is responsive to the supply of electricity to the self-regulating cable so that proper operation of the self-regulating heating cable assembly can be determined.
摘要翻译：一种改进的自调节管加热电缆组件，其包括在一对总线之间具有温度敏感导电层的自调节电缆和耦合到用于向其供电的自调节电缆的第一端的插头。改进的自调节管加热电缆组件包括在除了插头连接之外的位置处联接到自调节电缆的指示器。该指示器响应于自调节电缆的供电，从而可以确定自调节加热电缆组件的正确操作。

摘要： An improved thermostatic electrical cable heater is disclosed which permits more accurate temperature sensing by the thermostat and better control over the temperature of the object being heated. This improved sensing and temperature control is accomplished by isolating the thermostat and its surrounding insulated envelope from the electrical resistance heating elements of the cable heater.
摘要翻译：公开了一种改进的恒温电缆加热器，其允许通过恒温器进行更精确的温度感测并且更好地控制被加热物体的温度。这种改进的感测和温度控制通过将恒温器及其周围的绝缘外壳与电缆加热器的电阻加热元件隔离来实现。
