摘要： A cylindrical tube is open at both ends but divided into two portions by a barrier having an aperture therein. Side branches are connected to the tube either side of the barrier respectively, the side branches leading to a pressure transducer for deriving an airspeed indication. One open end of the tube is arranged to face into an airflow so that a pressure difference exists between the two portions, the pressure difference being measured by the pressure transducer through side branches. The barrier may have no aperture, the portions then being connected by a restricted passage disposed between the sides of the portions or between the side branches. The outside air temperature may be derived by the provision of a resistive element within the restricted passage.
摘要翻译：圆柱形管在两端开口，但是由其中具有孔的屏障分成两部分。侧分支分别连接到屏障的两侧，侧分支通向压力传感器，以得出空速指示。管的一个开口端被布置成面对气流，使得两部分之间存在压力差，压差由压力传感器通过侧分支测量。屏障可以没有孔，然后部分通过设置在部分的侧面之间或侧分支之间的受限通道连接。外部空气温度可以通过在限制通道内设置电阻元件来获得。
