Claim Text:
1. A gas sensor housing, comprising: a gas sensor, for establishment of a gas concentration on an active surface of the gas sensor, held by a housing body below a primary gas permeable diffusion membrane through which gas to be detected by the gas sensor will need to diffuse in accordance with Fick's second law of diffusion; at least one connector element moulded into the housing body such that the respective ends thereof enable connectivity to the gas sensor such that signals may be carried from the gas sensor to the connector element; a sensor envelope providing an enclosure for the housing body; a spacer section providing the necessary space for accommodating at least one connector lead connecting the at least one connector element with the gas sensor and thus a separation distance between the gas sensor and the primary gas permeable diffusion membrane providing a minimized volume space between the housing body and the primary gas permeable diffusion membrane and a minimized distance that the gas to be detected will have to diffuse to reach the active surface of the gas sensor; an inwardly protruding edge of the sensor envelope retaining the primary gas permeable membrane in place above the gas sensor and restricting movement of the primary gas permeable membrane away from the housing body; a secondary gas permeable diffusion membrane having electrically insulating properties ensuring that the at least one connector lead does not connect electrically to the primary gas permeable diffusion membrane between the spacer section and the primary gas permeable membrane.
