Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 1 to Fig. 4, a kind of continuous adjustable magnetic induction Wind tunnel sensor, comprises suspension ring 1, curved first gear aerofoil 2 and second gear aerofoil 3, dry reed switch 4 and permanent magnet 5.The upper end of first gear aerofoil 2 and second gear aerofoil 3 is rotatably connected by a turning cylinder, be fixedly connected with dry reed switch installing plate 6 and permanent magnet installing plate 7 respectively in the upper end of first gear aerofoil 2 and second gear aerofoil 3, and the entirety that first gear aerofoil 2 and dry reed switch installing plate 6 are formed is intersected mutually with the entirety that second gear aerofoil 3 and permanent magnet installing plate 7 are formed.Described dry reed switch 4 and permanent magnet 5 are arranged on dry reed switch installing plate 6 and permanent magnet installing plate 7 respectively; Wherein, permanent magnet 5 is connected with permanent magnet installing plate 7 by a location-plate 8, and permanent magnet installing plate 7 offers at least one bar hole 9, and when specifically implementing, described bar hole 9 is two, and is distributed in the both sides of permanent magnet 5, installation and stability maintenance better.Described location-plate 8 is locked with permanent magnet installing plate 7 through the lock bolt of location-plate 8 and bar hole 9 by (two), and location-plate 8 can drive permanent magnet 5 along bar hole 9 towards close dry reed switch 4 or move away from the direction of dry reed switch 4; Be convenient to people like this and regulate distance between permanent magnet 5 and dry reed switch 4 as required, thus air duct is monitored more accurately, reliable.Described dry reed switch 4 is installed on a circuit board, and is fixedly connected with dry reed switch installing plate 6 by this circuit board.
