Abstract

PURPOSE: To make connection between an electric circuit and an electrode feasible by providing a constitution under which an electrode connected to an electric circuit is fixed and a shutter plate shifting with a measurement element between electrodes is moved, thus detecting a change in electrostatic capacity.
CONSTITUTION: The primary fixed electrode plate 10 is almost of a ring shape and is positioned in a fixed manner on the base plate of a detector by means of a fixing leg 12. In the same way, the secondary fixed electrode plate 14 arranged opposed to the electrode plate 10 is shaped like a disc and is positioned on the base plate by means of te fixing leg 16. A shutter plate of disc shape 18 is inserted between the both fixed electrode plates 10, 14 and its shutter shaft 20 is connected to a measurement element. The shutter plate 18 migrates together with the shift of the measurement element, causing an electrostatic capacity between the electrode to change.
