Patent ID: 7032455

Claim:
A capacitive sensor device for measuring properties of a medium to be measured when this medium surrounds and flows past the sensor, where the sensor has a housing ( 3 ; 37 ; 42 ) of metal, with an opening ( 19 ) in the housing designed to accommodate one or more electrode(s) ( 1 ; 7 , 8 ; 12 - 14 ; 20 - 24 ; 38 - 40 ; 43 - 47 ), said electrode(s) being electrically insulated from said medium to be measured by means of a glass ceramic material ( 2 ; 41 ; 48 ) that is arranged to be flush with the outer surface of the sensor housing ( 3 ), characterised in that said opening ( 19 ; 37 ′; 42 ′) in the housing relative to the flow of said medium to be measured is located transversely thereof between two opposite faces ( 3 ′, 3 ″; 37 ′, 37 ″; 42 ′, 42 ″) of the sensor housing.
