Two-level detection device for aluminum electrolysis cell

A two-level detection device for an aluminum electrolysis cell belongs to the field of electrolysis and comprises a detection rod, the detection rod is suspended right above the aluminum electrolysis cell through a supporting column, a servo motor for driving the detection rod to ascend and descend is arranged on the upper portion of the supporting column, a detection core for detection is arranged on the lower portion of the detection rod, and the detection rod is hollow and filled with a high-temperature-resistant insulating material. The probe core penetrates through the interior of the detection rod through a wire and is led out from the upper end; and the lower end of the detection rod is provided with a support. The device is novel in conception, ingenious in design, capable of effectively, accurately and rapidly detecting the two levels of the aluminum electrolysis cell, the temperature of the electrolysis cell and the pressure drop of the furnace bottom, high in detection efficiency and high in detect
