Abstract
Various example embodiments described herein relate to a sensor assembly. The sensor assembly includes a first sensor cover and a second sensor cover. The first sensor cover is disposed on a first end of the sensor assembly and the second sensor cover is disposed on a second end of the sensor assembly. The first sensor cover defines a first capillary and the second sensor cover defines a second capillary therethrough. The sensor assembly further includes a first sensing unit, a second sensing unit, and a filter. The first sensing unit and the second sensing unit are disposed between the first sensor cover and the second sensor cover. In some example embodiments, the filter is reactive to a target gas and thereby prevents an inflow of the target gas through the second capillary into the sensor assembly.
