Abstract
A readily manufacturable heated solid electrolyte oxygen sensor. The sensor includes an elongated heater supported on a tubular reference electrode terminal in desired position relative to a solid electrolyte member within a cylindrical housing. The heater and terminal form a mutually electrically isolated subassembly in which the heater is in predetermined disposition with respect to the solid electrolyte member. An elongated heater is disposed within one or more ceramic sleeves that are in turn disposed within the electrode terminal tube. The heater, sleeves, and the terminal tube are vitreously bonded together to form a subassembly.
