Abstract

PURPOSE: To obtain a sensor of high reliability for sensing oxygen gas by usng the conjugated oxyde resistance material having characteristics of two or more kinds of saturation state of variation of resistance in the combustible gas component excessive atmosphere.
CONSTITUTION: La2O3 and CoO3 are blended, heated ground and molded to form the LaCoO3 resistance material having the perovskite type crystal structure and this resistance material is used as sensor. There may be some fear that the contact part between this resitance material and the power supplying electrode terminal is of high resistance, in accordance with requirement, glass composed of three components such as CaO, B2O3, SiO2 is blended with the resistance material before it is processed in firing. The resistance value of this resistance material indicates characteristic of two kinds of saturation state in the hydrogen excessive atmosphere. The segment of resistance material where the resistance range is equal to the 1st saturation point or less is used as sensor. Any resistance material indicating two or more kinds of saturation state can be used as sensor.
