PURPOSE:To detect accurately levels of powders and granules, etc. by providing a receiving plate swinging in contacting with surfaces of the powders and granules, etc. moving in an inner part of a rotating vessel and a detecting rod moving in up-and-down direction following the swing of the receiving plate. CONSTITUTION:A shaft 4 of the receiving plate 3 is inserted into a part protruded from a main body 1 of a rotating shaft 2, and a top end of a stopping screw 5 fixes the up-and-down movement by pressing. A plane part 2a whose one part is cut is provide to an upper part of the shaft 2 fitted to the body 1. A round hole 6 is formed above the main body of the part 2a, and the detecting rod 7 consisting of a piston part 7a and a rod part 7b is inserted into the hole 6, and the part 7a is fitted to the part 2a. By such a constitution, the levels of the powders and granules, etc. can be detected accurately. |
