Abstract
PURPOSE: To ensure a steady detection for existence of the subject of detection although the subject is flowing, by covering the insulated pipe of the level sensor with the anode and the cathode set opposite to each other and then connecting these anode and the cathode to the substrate which detects the variation of the electrostatic capacity.
CONSTITUTION: When the subject of detection passes through inside the insulated pipe 1, the electrostatic capacity increases by the dielectric constant of the subject. Thus the level sensor works. In this case, the electrostatic capacity increases assuredly at what place the subject may pass through within the pipe 1 since the pipe 1 is covered with the anode 2 and the cathode 3. As a result, the level sensor can be actuated without fail.
