Method and assembly for high angle of attack process parameter sensors

摘要

A method and an assembly for sensing a process parameter are provided. The sensing assembly includes a base and a sensor assembly. The sensor assembly includes a sensing element, a first flow channel, and a second flow channel. The first flow channel includes a converging segment, a straightening segment, and a turning segment wherein the turning segment includes a turn radius configured to separate particles from a flow entering the turning segment and the second flow channel is configured to generate a low pressure area downstream of the sensing element. The sensing assembly also includes an extension member extending between the base and the sensor assembly.
