3.产品工作原理及安装

Product Working Principle and Installation

	温控器中感温包接触到的被控介质温度升高时，感温包中的液体受热膨胀，当被控介质超过设定温度时，触点断开，系统自动切断电源、停止伴热。此时，感温包温度慢慢降低，被控温度低于设定温度时触点重新闭合，又自动恢复送电。
	The temperature sensor in temperature controller feels the temperature 0fthe controlled media increases, the liquid in the tensor swells. When the temperature 0fthe media exceeds the set point, the connecting point will separate, and then the power will be switched off and the heating stopped, And then the temperature decline slowly,ifbelow the set point, the connecting point will connect again and power connection is recovered,
	温控器安装时感温包只能水平安装和垂直向下安装，否则会出现温度不稳定现象。
	When installing temperature controller,temperature sensor shall be put horizontally and vertically,Otherwise the temperature is unstable
	先检查温控器通、断正常后，才能安装。
	Install only after check the connection and break of temperature controller is normal
