Description
Technical field
The utility model is related to parallel wire ring type current vortex sensor.
Background technology
In the prior art, the coil of current vortex sensor is surround and formed at grade using single enamel-covered wire, from
And an independent coil is formed, and had the disadvantage that using this kind of unicoil：
1st, monocoil inductance is easily disturbed, so less stable；
2nd, under the conditions of identical area coil, because unicoil inductance parameters are difficult to control, so as to cause the position of measurement
Shifting amount is restricted, and embodies the shortcoming that linearity measuring range is narrow, the range of linearity is narrow of displacement.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of certainty of measurement is high, measurement range wide and good stability
Parallel wire ring type current vortex sensor.
The technical scheme that the utility model is used is：The utility model includes housing, and the upper adaptation of the housing is set
There are coil group and signal processing circuit board, the coil group and the signal processing circuit board signal are connected, the signal transacting
Output signal cable is provided with circuit board.
Further, the coil group is formed by connecting by some coils from parallel connection of coils.
Further, the coil group includes the coil of several independences and queueing discipline, and the coil includes some
Enamel-covered wire, the enamel-covered wire closely, side by side, non-overlapped ground spiral surrounding is on the upper surface of the housing.
Yet further, the signal processing circuit board adaptation is arranged on the inside of the housing.
Again yet further, the signal processing circuit board includes low-power microprocessor, signal acquisition circuit and periphery
Circuit.
The beneficial effects of the utility model are：Set by the way of some enamel-covered wire spiral surroundings are on the upper surface of housing
The some coils being set to, coil group is constituted by way of parallel connection, and what is existed when can solve prior art using unicoil lacks
Point, for example, improve the linearity measuring range and the range of linearity of displacement, so as to improve certainty of measurement and the linearity, and effectively expands
Measurement range；Using multi-coil, its inductance is difficult to be disturbed, so stability is preferable；Used due to signal processing circuit board
It is low-power microprocessor, there is energy-saving effect again.
Brief description of the drawings
Fig. 1 is side sectional view of the present utility model；
Fig. 2 is top view of the present utility model.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model include housing 1, the housing 1 be non-metal shell, the housing 1 it is upper
Adaptation is provided with coil group 2 and signal processing circuit board 3, and the coil group 2 and the signal processing circuit board 3 pass through wire phase
Connection, is provided with output signal cable 4 on the signal processing circuit board 3, the coil group 2 is connected in parallel by some coils 5
Form.When test job is done using the utility model, the utility model there need to be one end of the coil group near tested
Part, now according to faraday electromagnetic induction principle, the signal processing circuit board 3 will collect what the coil group 2 was produced
Frequency signal, then the signal processing circuit board 3 calculates displacement data signal, then the displacement data signal is led to
Cross the output signal cable 4 and be transferred to external device；On the other hand, housing uses nonmetallic materials because metal material meeting
Influence test result, and the signal processing circuit board 3 is adapted to the inside for being arranged on the housing 1 so that the signal transacting
Circuit board 3 is protected well by the housing 1.
The utility model can be used for current vortex sensor testing field.
