Radioactive waste resin interface measuring device based on magnetostrictive liquid level meter

The invention discloses a radioactive waste resin interface measuring device based on a magnetostrictive liquid level meter, which comprises a magnetostrictive liquid level meter, and the magnetostrictive liquid level meter comprises a water level floater and a resin floater; the measuring device further comprises a traction device, a cable and a lifting claw. The cable is connected with the traction device, and the lifting claw is fixed on the cable; the lifting claw is located below the resin floater, and when the traction device drives the lifting claw to ascend through the cable, the resin floater is lifted by the lifting claw; the measuring device further comprises a box body and a control box, the meter head and the traction device are both arranged in the box body, and the meter head and the traction device are both in data communication connection with the control box. The resin interface with irradiation is measured through a method of combining a magnetostriction liquid level meter measurement princ
