レベル検出装置。[Claims for Utility Model Registration] (1) A level detection device placed in a powder or liquid tank to detect the level in the tank, which uses a rod-shaped or band-shaped magnetic sensor with flexibility. A cylinder with a bottom or a lid is covered with a cover body, and magnets are attached at predetermined intervals in the longitudinal direction of the cover body to draw air inside the cylinder from the upper or lower direction of the cylinder. The cover body is made to make an oscillating motion so that air can be repeatedly supplied to the inside of the body, and the level in the tank is detected by detecting a magnet close to the magnetic sensor by the pressing force of the powder or granules in the tank. A level detection device for powder, etc., characterized by being able to detect. (2) A magnetic sensor is disposed in a pipe having an elongated opening in the axial direction, and a cover body is formed around the elongated opening so that the diameter thereof is slightly larger than that of the pipe to form a cylindrical body. The level detection device for powder etc. according to claim 1.
