Abstract
A method and an assembly for sensing a process parameter are provided. The sensor assembly includes a base, a pedestal including a body extending between a leading edge and a trailing edge in a direction of fluid flow past the body, a first edge of the pedestal coupled to the base, a second edge opposes the first edge. The sensor assembly also includes an airfoil extending from the pedestal, a leading edge of the airfoil aligned with the leading edge of the pedestal, the airfoil extending in a direction of a flow of fluid along the second edge. The sensor assembly further includes a sensor element extending from the second edge spaced apart from the airfoil by a first gap, and a shield at least partially surrounding the sensor element, the shield spaced apart from the airfoil by a second gap defining a fluid flow inlet to the sensor element.
