Description
Technical field
The present invention relates to displacement transducer technology field, and in particular to a kind of three-wire system LVDT wire winding.
Background technology
Displacement transducer is also known as linear transducer, is a kind of linear unit for belonging to metal sensing, the effect of sensor
It is that various measurands are converted to electricity.Common are three-wire system LVRT GE, fin-plate type three-wire system LVDT, but this two
The unique sensor of type is due to Magnetic field inhomogeneity, and appearance and size is all very long, such as the product of Japan LS series, its profile and U.S.
State's GE products are the same, and for example Japan LS-300 appearance and size is φ 32x686mm, and U.S. GE-6 (LVRT) appearance and size is
φ 32x685.8mm (i.e. 27 inches), the linearity is up to 0.2%, but temperature coefficient is 0.03%/F.S/ DEG C.And for example layer wound three
Line LVDT, linearly degree is 0.5% to Wuxi Helie Transducer Co., Ltd.'s TD-1 series of products, temperature coefficient 0.03%/
F.S/ DEG C, appearance and size is then relatively short.Therefore active demand is a kind of both has shorter appearance and size, also possesses smaller simultaneously
The three-wire system LVDT of linearity wire winding, to meet use demand.
The content of the invention
In order to solve the deficiency in the presence of prior art, the present invention proposes a kind of three-wire system LVDT wire winding.
A kind of three-wire system LVDT wire winding, the processing step is as follows：
The first step：Secondary I coiling：
Coiling is at 230mm since midpoint, secondary I is close around 2 layers to the right, and every layer 662.8 is enclosed, and spacing is 0.346mm；
3rd layer is spaced winding A, and close around 331.4 circles, spacing is 0.346mm, spaced winding A；
4th interlayer pulls out a lead-out wire, with left half of 5th layer of initial in external connection around A；
Second step：Secondary II coiling：
Secondary II is close around 2 layers, every layer 662.8 circle, spacing 0.346mm to the left from midpoint；
3rd layer is enclosed to be close around 331.4, and spacing is 0.346mm, spaced winding B；
4th interlayer is around B, subsequently around right half of 5th layer, and close around 331.4 circles, spacing is 0.346mm, spaced winding B；
6th interlayer terminates as secondary II tail around B；
Left one side of something is since the 5th layer of midpoint, and close around 331.4 circles to the left, spacing is 0.346mm, spaced winding A；
6th interlayer terminates as secondary I tail around A；
3rd step：Left half of 5th, 6 layers with the right half of 1st, 2,3,4 layers of secondary I whole coil of composition.
The beneficial effects of the invention are as follows：The present invention is only arranged, two groups of coils without primary coil with secondary by arithmetic series
Concatenation, the linearity is 0.2%, and temperature coefficient is 0.014/F.S/ DEG C, and the product being made according to technical scheme had both had
For the shorter appearance and sizes of TD-1 series of products, also it ensure that the linearity is up to state standards simultaneously.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is coiling schematic diagram of the invention；
Fig. 2 is the spaced winding A of present invention coiling schematic diagram；
Fig. 3 is the spaced winding B of present invention coiling schematic diagram；.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, below it is right
The present invention is expanded on further.
As shown in Figure 1 to Figure 3, a kind of three-wire system LVDT wire winding, the processing step is as follows：
The first step：Secondary I coiling：
Coiling is at 230mm since midpoint, secondary I is close to the right, and around 2 layers, every layer 662.8 is enclosed, and spacing is 0.346mm, around
Line direction is as illustrated by the arrows in fig. 1；
3rd layer is spaced winding A, and close around 331.4 circles, spacing is 0.346mm, and spaced winding A is shown in Fig. 2；
4th interlayer pulls out a lead-out wire, with left half of 5th layer of initial in external connection around A；
Second step：Secondary II coiling：
Secondary II is close around 2 layers to the left from midpoint, and every layer 662.8 is enclosed, spacing 0.346mm, and direction is as illustrated by the arrows in fig. 1；
3rd layer is enclosed to be close around 331.4, and spacing is 0.346mm, spaced winding B, sees Fig. 3；
4th interlayer is around B, subsequently around right half of 5th layer, and close around 331.4 circles, spacing is 0.346mm, spaced winding B；
