  • Corrosion Protection for Pressure Sensors
    Publication number: 20070279845
    Abstract: The present invention describes a device having a housing and at least one electrical component, the housing having at least one of the electrical components and being filled at least partially by a passivating agent. Furthermore, it is provided that the electrical component is covered at least partially by the passivating agent. Now, the crux of the present invention is that an additional material layer is applied on top of the passivating agent. Using this additional material layer, a device is able to be implemented in a simple and cost-effective construction, that is resistive to environmental damages. This makes possible using electrical components in corrosive environments.
