４.Working Principle |
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. |
５.Product Characteristics And Applications |
Our company’s temperature controller are national patent products. It has following advantages: deft design, nice figure, convenience to use, easy to installation. One controller can control working of two-way heating cable, when the heating cable is operation the indicator is lit. It has temperature control switch on the top cap and the installation direction is can be changed by the spinning of the low cover. Open the top cap can measure the insulation resistance and power for the heating cable. |
