置。 The float 1, which moves up and down along the lifting guide 8 in response to the rise and fall of the water surface l1 in the sewage treatment tank 12, is provided with vertical surfaces 2a and 2b facing each other with a predetermined gap g maintained therebetween, so that the float 1 moves up and down within the tank within the gap g. The light projection surface 3a is formed so that the liquid flows therethrough, and the light projection surface 3a is formed at a predetermined interval through the liquid in the tank.
The sensing section 3 of the transmission type optical sensor S is disposed so that the light receiving surface 3b and the light receiving surface 3b are concentrically opposed to each other, and the sensing section 3
The buoyancy of float 1 is set so that l is located at an arbitrary predetermined depth below the liquid surface of the tank liquid, and the sludge interface l
In the sludge settling interface detector, which is configured to detect an increase in transmitted light caused by passing the light sensor 2 through the location where the optical sensor sensing section 3 is disposed, the wiper 9 that is in sliding contact with the vertical surfaces 2a and 2b is moved between Supported in position by a support mechanism introduced in g,
A sludge settling interface detection device characterized in that the vertical surfaces 2a and 2b are wiped by a wiper 9 and slide up and down as the float 1 moves up and down.
