Abstract

PURPOSE: To make stable the sensitivity to temperature, by using silver or gold solder for the contact media for the opposing surfaces between the metal case in common use with the piezoelectric porcelain material and electrode and the metal damper.
CONSTITUTION: At the bottom of the stainless steel case 1, the piezoelectric element 2 is contained via the silver solder 3a in common use for the contact media and one electrode, and the metal damper 5 is in contact on the element 2 via the silver solder 3b being in common use for another electrode, and the insulation cylinders 4a, 4b are contained in the case 1. The case is inserted in the vacuum furnace after assembling, it is heated to the temperature more than the melting point of the silver solder and then cooled. With this method, since the bonding between the metals can completely be made, the sensitivity of the probe to temperature can be made stable.
