ABSTRACT:
A capacitive sensor device for measuring properties of a medium to be measured when this medium surrounds and flows past the sensor. The sensor has a housing of metal, an opening in the housing transverse to the flow of said medium to be measured which is adapted to house at least one capacitive electrode, and where the electrode(s) of the sensor is/are electrically insulated from said medium to be measured by means of a glass ceramic material that is arranged to be flush with the outer surface of the sensor.
