3.產品工作原理及安裝

Product Working Principle and Installation

	溫控器中感溫包接觸到的被控介質溫度升高時，感溫包中的液體受熱膨脹，當被控介質超過設定溫度時，觸點斷開，系統自動切斷電源、停止伴熱。此時，感溫包溫度慢慢降低，被控溫度低于設定溫度時觸點重新閉合，又自動恢復送電。
	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,
	溫控器安裝時感溫包只能水平安裝和垂直向下安裝，否則會出現溫度不穩定現象。
	When installing temperature controller,temperature sensor shall be put horizontally and vertically,Otherwise the temperature is unstable
	先檢查溫控器通、斷正常后，才能安裝。
	Install only after check the connection and break of temperature controller is normal
