Abstract

A protective cover assembly of a gas sensor which is made up of an inner and an outer cover. The inner cover is disposed within the outer cover coaxially through a given clearance. The dimension of the clearance is defined within a range suitable for improving the response rate of the gas sensor while ensuring the effect of avoiding the damage such as cracks in a sensor element arising from wetting thereof with moisture contained in a measurement gas.
