General Description
BJW82A-120/15|BJW84A-120/15防爆溫度控制器符合GB3836.2-2000的防爆規(guī)定，防爆標(biāo)志為ExdIIBT4,。在 II 類一區(qū),、二區(qū)危險(xiǎn)場所供溫控器與電伴熱帶配套使用，用于自動(dòng)控制管線或罐體溫度,。
The explosion proof temperature controller complies with the requirements specified in G83836.2 … 2000. The explosion proof mark is Exd II BT4.The temperature controller is used combined with electric heating cable in Zone 1, 2,Grade II. It is applied to controlling temperature automatically of pipes or tanks.
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,
