Broadband lambda probe and production method for a broadband lambda probe

摘要

A broadband lambda probe includes a measurement hollow space. The broadband lambda probe further includes an oxygen pump cell having an outer pump electrode and an inner pump electrode to enable the transfer of oxygen from the measurement hollow space to an external environment of the broadband lambda probe. The broadband lambda probe further includes a Nernst concentration cell. The broadband lambda probe further includes at least one capacitive sensor device. The at least one capacitive sensor device has a capacitance configured to be varied with a change of a concentration of at least one substance. The concentration is present in the respective at least one capacitive sensor device. The at least one capacitive sensor device is positioned in the broadband lambda probe to at least one of directly adjoin the measurement hollow space and partially project into the measurement hollow space.
