れがあった。Although the conventional devices described above have excellent heat resistance, corrosion resistance, and mechanical strength, they require a double seal boundary structure as a design condition of the conductor penetration element, so it is difficult to connect the conductor within the conductor penetration element. This has the drawback that a temperature error occurs due to this connection location and a temperature gradient between both sides of the end plate 3. Furthermore, since two sealing fittings are required for one conductor, the number of conductors accommodated in the conductor penetrating element is limited by the dimensions of the sealing fitting. Furthermore, since each conductor is individually attached to the end plate, there is a risk of damaging the thermocouple element during the manufacturing stage.
