A measurement guard for an outlet line of an aircraft environmental control system component

Abstract

The utility model provides a kind of for the measuring protection device of aircraft environmental control system component outlet pipeline, including the flow guide component being arranged on the main pipeline of component outlet pipeline, protective cover and sensor support, flow guide component and sensor support are sequentially arranged along airflow direction, sensor support is provided with sensor interface piece, for installing temperature sensor;Protective cover and sleeve set on sensor interface piece, for accommodating the detection head of temperature sensor, provide a relatively stable measuring environment for temperature sensor, a plurality of through holes are opened on the wall of protective cover;Flow guide component includes flow guide plate, flow guide plate is vertically arranged on main pipeline, the projection of flow guide plate along the axis direction of main pipeline can completely cover protective cover, effectively guide airflow, reduce the friction and impact of airflow to temperature sensor, sensor support, to reduce the dynamic interference of airflow to temperature sensor, simultaneously, reduce the condensation and icing risk of water vapor on the surface of sensor support, improve the accuracy of temperature measurement.
