Abstract

A gas sensor includes a sensor housing, and a sensing element located within the sensor housing, the sensing element defining an axis and having a distal end extending from the sensor housing. The gas sensor further includes a sensor protection element coupled to the sensor housing and at least partially surrounding the distal end of the sensing element. The sensor protection element includes a tube, the distal end of the sensing element located within the tube, the tube including a window located along a side of the tube adjacent the distal end of the sensing element. The sensor protection element further includes a fabric layer positioned adjacent the window, the fabric layer spaced from the sensing element and extending generally parallel to the axis.
