Abstract

The invention relates to a sensor (1), in particular a capacitive level sensor comprising a sensor housing (3) and a sensor element (5), which is provided with an insulation layer and which is fixed to the sensor housing (3), said insulation layer (7) consisting of a fireproof, non-metallic material and forming a hermetically tight seal between the sensor element (5) and the sensor housing (3). The invention also relates to a method for producing a sensor (1) of this type.
