Abstract: A sensing system that includes a cylindrical body including an internal flow channel that channels a first fluid therethrough, and a sampling chamber. The sampling chamber is in flow communication with an ambient environment. A venturi device is coupled within the cylindrical body, and the venturi device includes a high pressure portion and a low pressure portion. The low pressure portion is in flow communication with the sampling chamber. A valve is coupled within the cylindrical body and is positionable in at least a first position. A first flow channel is defined between the internal flow channel and the high pressure portion through the valve. The first flow channel channels the first fluid towards the high pressure portion such that the low pressure portion draws a second fluid into the sampling chamber from the ambient environment. A sensor assembly determines characteristics of the second fluid within the sampling chamber.
