| Zusammenfassung: | To cause a detection part of a fluid sensor to be easily distorted by fluid.SOLUTION: A fluid sensor comprises a detection part having a flexible part 110, a first obstacle 130, and a first detection part 200a. The flexible part extends in a Z-Z' direction. The first obstacle extends in the Z-Z' direction, has a dimension in a Y-Y' direction being smaller than a dimension of the flexible part in the Y-Y' direction, and is arranged upstream of the first obstacle with a space therebetween. Due to the collision of the fluid with the first obstacle, a vortex is caused to occur in the fluid on the downstream side of the first obstacle. Due to the collision of the vortex with the flexible part, at least a portion of the flexible part is distorted. At least one sensor part of the first detection part detects the distortion of at least a part of the flexible part as a flow of the fluid.SELECTED DRAWING: Figure 2A
【課題】流体によって流体センサの感知部を歪み易くする。【解決手段】流体センサは、可撓部１１０を有する感知部と、第１障害物１３０と、第１検知部２００ａとを備えている。可撓部はＺ－Ｚ'方向に延びている。第１障害物は、Ｚ－Ｚ'方向に延びており、Ｙ－Ｙ'方向の寸法が可撓部のＹ－Ｙ'方向の寸法よりも小さく且つ第１障害物に対して上流側に間隔をあけて配置されている。流体が第１障害物に衝突することによって第１障害物の下流側で流体に渦を発生させる。渦が可撓部に衝突することによって可撓部の少なくとも一部が歪む。第１検知部の少なくとも一つのセンサ部は、可撓部の少なくとも一部の歪みを流体の流れとして検知する。【選択図】図２Ａ |
