    • A temperature probe has an elongated spindle-like body with an axial bore of uniform diameter extending entirely therethrough. The forward end of the probe has a knife-sharp edge surrounding the bore opening for ice-free performance. An annular air intake in the bore wall leads to an annular, rearwardly and radially outwardly extending sensor channel containing a bare wire element in an annular zig-zag pattern relative to air flow in the channel. The channel has an outlet near the radially widest part of the probe body, allowing venturi action of the exterior air stream to aid in drawing air through the channel from the bore. A heating element may be mounted downwind of the sensor element. The channel and sensor element are radiation shielded by a hollow area in the probe body between cooperating walls, and bleed holes may direct boundry layer air into the hollow area upwind of the sensor element and out of the hollow area downwind of the sensor element.
    • 温度探头具有细长的心轴状体,其具有均匀直径的轴向孔,其完全贯穿其中。 探头的前端具有围绕孔开口的锋利边缘,用于无冰的性能。 孔壁中的环形空气入口相对于通道中的空气流通向环形,向后和径向向外延伸的传感器通道,其包含环形锯齿形图案的裸线元件。 通道在探针主体的径向最宽部分附近具有出口,允许外部空气流的文氏管作用以帮助从孔中吸入空气通过通道。 加热元件可以安装在传感器元件的下风向上。 通道和传感器元件由探针主体中的协调壁之间的中空区域辐射屏蔽,并且排放孔可以将边界层空气引导到传感器元件的中空区域中,并将其传送到传感器元件的下风向中空区域之外。

    • PURPOSE:To prevent the generation of an impulse wave and the collision of reverse fuel particles at the time of a backfire by providing a temperature sensitive element such as a thermistor in an air intake duct in an exposed state and providing a buffer means or protection cylinder on its downstream side. CONSTITUTION:The protection cylinder 20 has an opening 20A facing the upstream side of the air intake duct 1 and opening 20B and 20C almost at right angles to it, and is closed on the downstream side of the air intake duct 1. Then, the pressure of suction air is relatively lower than impulsive pressure at the time of a backfire, so the air flows out of other openings 20B and 20C smoothly. Thus, the temperature of the suction air is measured by the temperature sensitive element 11.
    • 目的:为了防止产生冲击波,在反火时产生反向燃料颗粒碰撞,通过在暴露状态的空气进气管道中设置热敏电阻等温度敏感元件,并提供缓冲装置或保护筒 在其下游。 构成:保护筒20具有面向进气管1的上游侧的开口20A和大致与其成直角的开口20B和20C,并且在进气管1的下游侧封闭。然后,压力 吸入空气相对低于回火时的冲击压力,所以空气流畅地流出其它开口20B和20C。 因此,吸入空气的温度由温度敏感元件11测量。
