ABSTRACT:
A lean sensor for sensing oxygen concentration in exhaust emissions, including a sensor element consisting of a tabular solid electrolyte having opposed sides provided with electrodes with at least one surface thereof coated with a porous coating layer, an element fixing plate having an element fitting hole to which the element is fitted, and a pair of heat-resistant insulating support plates having opposing windows and clamping therebetween the element fixing plate together with the sensor element disposed in the windows. In this way, it is possible precisely to locate the element in relation to the plate and to improve the bonding strength and reliability while reducing the size of the sensor as a whole.
