Abstract:
A method of coating a ceramic cylindrical carrier body having a cylindrical axis, an exterior surface jacket, a first end face, a second end face, and a series of channels extending from the first end face to the second end face, the method comprising:vertically aligning a cylindrical axis of the carrier body so that one of the end faces of the carrier body is a lower end face, and the other end face of the carrier body is an upper end face; introducing a coating suspension into the series of channels of the carrier body through the lower end face, to fill the carrier body with a filling volume of the coating suspension to a predetermined height of the carrier body, which height is only a portion of an entire length of the carrier body; and removing excess coating suspension from the carrier body downward through the lower end face of the carrier body, wherein a capacitive sensor is positioned at the predetermined height at a distance from an exterior surface jacket of the carrier body to signal when the coating suspension inside the carrier body has reached the predetermined height to cease the filling of the carrier body.
