Method of manufacturing a sensor element

Abstract

A method for manufacturing a sensor element for a potentiometric sensor includes: forming a glass layer made of an electrically insulating glass on a surface of a base body, in particular a base body made from an electrically insulating material; arranging a substrate made of copper or a copper-based alloy having a mass fraction of at least 60% copper on the glass layer; covering the substrate arranged on the glass layer with a glass body, for example a glass plate, made of an ion-selective, in particular pH-selective, glass; and subsequently controlling the temperature of the arrangement of the base body, substrate and glass body thus formed in such a way that the substrate is integrally bonded to the glass body made of the ion-selective glass and the glass layer on the surface of the base body.
