摘要： The measuring sensor, particularly a lambda probe, has a ceramic sensor member retained at a high temperature during measuring operation. It is shielded from water droplets, carried along in the gas to be analyzed, by a heated protective housing, permeable for the gas to be analyzed, by which water droplets carried along in the direction of the sensor member are evaporated before reaching the sensor member. In this way, the water droplets are unable to cause any shock-like temperature drops at spots on the surface of the sensor member or material flaking.

The housing is fixed via a predefined tightening torque in the receiving element.

摘要： A combination of a measuring sensor and protector having a measuring sensor with a housing and having an elongated cup-like protective pipe engaged with the housing. The pipe has a bottom having a convex shape with an inlet opening. The pipe also has at least one outlet opening spaced away from the bottom. A deflector extends inward from the pipe at an acute angle relative to a longitudinal axis of the pipe and away from the bottom so that when gas flows longitudinally within the pipe from the inlet opening, the gas is deflected by the deflector to flow around the deflector to the at least one outlet opening. The bottom also has a boss-like bulging portion projecting outward to form the inlet opening so as to reduce contamination of the measuring element by preventing solid particles in the gas from entering inside the pipe.
