Abstract
A self heating, readily assembleable solid electrolyte oxygen sensor is provided. A heater subassembly readily adaptable to unheated oxygen sensor technology, provides the means for positioning and rigidly securing the heater element within the oxygen sensing device through the use of locating means on the heater element and corresponding locating projections on the electric connector terminals. The terminals also provide the means for electrically coupling the resistance heating wires of the heater element to the external ground and power signals.
