1. A measuring sensor for detecting gaseous components in the ambient, the measuring sensor comprising:

  • a support body having an end face and defining a chamber;

    an electrolyte disposed in said chamber;

    a permeable, electrically-conductive coating on said end face;

    break through means extending from said chamber to said end face for permitting said electrolyte to penetrate to said coating;

    said coating being applied to said end face so as to form an adhering interface;

    a membrane separating said electrolyte from the ambient containing the gaseous components and being permeable to said gaseous components;

    said membrane being impermeable to said electrolyte in a lateral direction between said support body and said coating and being applied to said coating so as to form an adhering connection with said coating;

    an electrical signal lead connected to said coating so as to cause said coating to define a measuring electrode and have an electrochemically active surface at said interface; and

    ,a counter electrode disposed in said electrolyte.
