Abstract

PURPOSE: To improve sealability and productivity by arranging an electrode rod in the center hole of a cylindirical main member and by filling up the space inbetween with such an insulating resin as has a higher thermal expansion coefficient than those of the two.
CONSTITUTION: A liquid detecting electrode divice, which is prepared by inserting an electrode rod 1 and a cylindrical main member 2 of stainless steel into molds and by coating them with an insulating resin 3, screws a externally threaded portion 21 of the main member 2 into the internally theraded portion of a boiler wall so that it may be used for liquid control. Since the thermal expansion coefficient of the insulating resin 3 is made higher than those of the rod 1 and the member 2, the jointed interface (a) between the rod 1 and the resin 3 can have the higher sealability as the temperature drops the more, whereas the jointed interface (b) between the member 2 and the resin 3 can have the higher sealability as the temperature rises the more. The space, which is extablished at the interface (b) when the temperature is low, can be prevented from have its sealability deteriorated by the sealability of a jointed interface (c) between the both ends of the main member 2.
