They can only measure the temperature at that fixed position, but not the temperature at other positions. As the asphalt liquid level in the oil spill tank rises or falls, the temperature of the asphalt heating cannot be accurately controlled, resulting in the asphalt temperature being too low during oil dispensing, causing damage to the oil dispensing equipment, or the asphalt temperature being too high, causing damage to the asphalt quality. Therefore, it is necessary to design and modify the asphalt temperature measuring thermal conductivity thermometer to effectively prevent inaccurate temperature measurement. Utility Model Content
