Sensor element for gas sensor for determining physical characteristics of measuring gas, particularly exhaust gas from internal combustion engine, has sensor body in which cavity is formed with gas entrance hole
The sensor element has a sensor body (11) in which a cavity (13) is formed with a gas entrance hole (12) discharged at the body upper surface. A protective layer (14) is provided that partially covers the body upper surface leaving the opening (121) of the gas entrance hole. The protective layer is...

| description | The sensor element has a sensor body (11) in which a cavity (13) is formed with a gas entrance hole (12) discharged at the body upper surface. A protective layer (14) is provided that partially covers the body upper surface leaving the opening (121) of the gas entrance hole. The protective layer is formed of stratified materials applied on the body upper surface. An upper surface zone of the body upper surface has a non-stick characteristic for the stratified materials. The upper surface zone surrounds the opening of the gas entrance hole. An independent claim is included for a method for manufacturing a sensor element for a gas sensor for determining physical characteristics of measuring gas, particularly exhaust gas from an internal combustion engine.
Es wird ein Sensorelement für einen Gassensor zur Bestimmung mindestens einer physikalischen Eigenschaft eines Messgases, insbesondere des Abgases einer Brennkraftmaschine, angegeben, das einen Sensorkörper (10) mit einem an der Körperoberfläche in einem Gaszutrittsloch (12) mündenden Hohlraum (13) und eine die Körperoberfläche mindestens teilweise bedeckende Schutzschicht (14) aufweist. Um ein Zusetzen des Gaszutrittslochs (12) beim Auftragen des Schichtmaterials für die Schutzschicht (14) zu verhindern, weist eine die Mündung (121) des Gaszutrittslochs (12) umschließende Oberflächenzone (26) der Körperoberfläche des Sensorkörpers (11) Antihafteigenschaften für das Schichtmaterial auf. |
