A gas sensor for being placed into a gas stream such that the gas sensor is insensitive to any specific rotational orientation about a longitudinal axis of the sensor within the gas stream. The sensor includes 1) a base having an axis that is perpendicular to the gas stream, 2) a sensor element on the base, 3) a catalyzed sensor element on the base proximate the sensor element, for creating an exothermic reaction upon contacting the gas stream thereby forming a heated gas stream portion, and 4) the catalyzed sensor element and the sensor element are positioned on the base with a sufficient axial separation therebetween so that as the base rotates about the axis, the heated gas stream portion will not contact the sensor element. In particular, the base has a second axis being perpendicular to the axis and separating the sensor element from the catalyzed sensor element. Additionally, the invention provides a device that may have both the sensor element and the catalyzed sensor element including a longitudinal axis. Wherein, both the sensor element and the catalyzed sensor element may have many different shapes. Both the sensor element and the catalyzed sensor element may have two or three sides that are coextensive with at least one void. As a result of having a void the base may include a bridge that connects at least one side of the sensor element and the catalyzed sensor element to the base.

[ What is claimed and desired to be secured by Letters Patent is:] [1.] A gas sensor for being placed into a gas stream and designed to be insensitive to a specific rotational orientation while performing measurements on the gas stream, comprising:a) a base having an axis that is at an angle to the gas stream;b) a sensor element positioned on the base, for sensing a first temperature at a first point along the gas stream;c) a catalyzed sensor element, positioned on the base, for both creating an exothermic reaction upon contacting the gas stream thereby forming a heated gas stream portion having a second temperature equal to or hotter than the first temperature, and sensing the second temperature at a second point along the gas stream proximate the first point; andd) the catalyzed sensor element and the sensor element are positioned on the base with a sufficient separation along the axis therebetween so that as the base would rotate about the axis the heated gas stream portion created by the catalyzed sensor element would not contact the sensor element.
