Embodiment
Principle of work of the present utility model is: water level gauge float lifting thereupon during fluctuation in stage, the band dynamic water level wheel 1 by linking to each other with float rotates, and makes the rotation with the coaxial induction wheel 2 of water level wheel 1.Sensing chip 8 on the induction wheel 2 is arranged in the magnetic core 3 formed magnetic fields of popping one's head in, and sensing chip 8 produces electromagnetic induction signal with disconnected ground of induction wheel 2 rotation times cutting magnetic field.Magnetic core probe 3 is converted to electric impulse signal with electromagnetic induction signal, by calculating electric impulse signal and converting, can get the height of fluctuation in stage.
The sensing chip 8 of induction wheel 2 is 8, and when the magnetic core 4 of magnetic core probe 3 was two, the utility model mainly was made up of with circuit sealing pipe 6 water level wheel 1, induction wheel 2, magnetic core probe 3, sees Fig. 1.
The traction rope that hangs ball float and balance bob is arranged on the water level wheel 1,
The spacing of sensing chip 8 and the central angle alpha of width are 22.5 °,
Be fixed with two magnetic cores 4 on the magnetic core probe 3,
Magnetic core 4 formed magnetic directions and sensing chip 8 cutting magnetic line directions are perpendicular and be positioned at sensing chip 8 rotation cutting zones;
The magnetic core 4 of magnetic core probe 3 is two, it is the rotation direction that to distinguish induction wheel 2 because of two magnetic cores 4, thereby, can distinguish that water level is to rise or descend, therefore the number of magnetic core probe 3 should be limited in the even number more than or equal to two, as 2,4,6,8 etc., be the simplest but magnetic core probe 3 is two a embodiment, the most practical.
Therefore sensing chip 8 numbers should be even numbers and unsuitable too many, and the spacing of too many electric impulse signal can be too little, are difficult to distinguish, and sensing chip 8 is made troubles adding man-hour in addition; Very little, as 2, have too many no clipping time again, induction wheel 2 also will rotate, and causes waste.Sensing chip 8 cutting spacings increase, and the number of times of unit interval cutting reduces, so signal resolution decline, has increased measuring error.So the scope of the number of sensing chip 8 be 6～10 can, be advisable 8 the bests with 6 or 8.
During work, water level wheel 1 rotates, and drives the induction wheel 2 coaxial with it, and two fixing magnetic cores 4 on the cutting magnetic core probe 3 produce the magnetic-pulse signal, are transferred to the circuit board 7 that is sealed in the circuit sealing pipe 6, are transformed into electric signal and show.Because two magnetic cores are arranged, can judge induction wheel by cutting sequence, just the rotation direction of water level wheel is forward rotation or backward rotation, thereby can judge that water level is to rise or descend.For example: when fluctuation in stage 32cm, water level wheel and induction wheel are rotated a circle be 360 °, 16 magnetic fields of 8 sensing chips cuttings on the induction wheel, then the positive and negative square wave Kazakhstan of magnetic core probe induction output is 32 electric impulse signals.Then the conversion relation of fluctuation in stage and electric impulse signal is: an electric impulse signal, fluctuation in stage 1cm.
