Abstract
A round full-bridge resistance strain gage belongs to a round resistance strain gage with a laminar structure and adopts the scheme that an outer-ring strain gage and an inner-ring strain gage have an inner-outer structure and are adhered on a round multifunctional lug plate and then pressed to form a whole body, and an outgoing line is welded on the round multifunctional lug plate. According to the round full-bridge resistance strain gage, the yield of strain gage finished products is enhanced greatly, the problem of restriction on a plaster area in sensor production is saved, the strain gage manufacture is simplified, the operation in the sensor production is simplified, and the stable performance of sensors is ensured.
Description
Technical field:
The utility model relates to a kind of circular full-bridge strain ga(u)ge of laminar structure, especially a kind of circular full-bridge strain ga(u)ge that carries lug plate.
Background technology:
In the prior art; Strain ga(u)ge is used for the especially special-purpose weighing apparatus of working pressure sensor of special-purpose weighing apparatus, because full-bridge diaphragm grid strainometer is mostly used in the restriction of elastomer structure pattern and strainometer Chip Area domain sizes; This diaphragm grid strainometer all is one-time formed planar structures; Promptly all wire grids are formed in the film substrate of same garden simultaneously, have the problem that the processing technology difficulty is big, product qualified rate is low, and use occasion needs to add in addition special-purpose lug plate; Complicated operation causes the reduction of sensor performance easily.
The utility model content:
The utility model is exactly not enough to existing in prior technology; A kind of circular full-bridge strain ga(u)ge is provided; This strainometer has solved the restricted problem in paster zone in the sensor production, and has simplified the strainometer making when improving the strainometer product qualified rate greatly; Simplify the operation of sensor production, guaranteed the stable of sensor performance.
The scheme that its technical matters of the utility model solution is taked is: a kind of circular full-bridge strain ga(u)ge; It is characterized in that; External and internal compositions is counted in outer ring strainometer and inner ring strain; The two is bonded on the circular multi-functional wiring sheet, forms a whole through pressing, is welded with extension line on the circular multi-functional wiring sheet.
Described outer ring strainometer, inner ring strainometer and circular multi-functional wiring sheet are unit independently before pressing.
This circular full-bridge resistance-strain is counted fully independently product, and outer ring strainometer and inner ring strainometer are designed to the strainometer of independent moulding separately, binds with the multi-functional wiring sheet of circle, lamination, and superimposed back forms circular full-bridge strain ga(u)ge.The circular multi-functional wiring sheet while is as the surperficial cap rock of strainometer lug plate and full-bridge strainometer.This product design size, outward appearance and common diaphragm grid strainometer are roughly the same, but need not to add the lug plate of drawing signal in addition as common diaphragm grid strainometer when using.
The beneficial effect of the utility model is:
1) the utility model structure and technology are simple, can improve the product qualified rate of diaphragm grid strainometer.
2) need not to add special-purpose lug plate in addition during sensor patch, simplified the operation of sensor production, guaranteed the stable of sensor performance.
Description of drawings:
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the simple and easy diagrammatic cross-section of the utility model.
Among the figure: 1 outer ring strainometer, 2 inner ring strainometers, 3 circular multi-functional wiring sheets.
Embodiment:
Like Fig. 1, shown in Figure 2, the circular full-bridge strain ga(u)ge of this kind, outer ring strainometer 1 and inner ring strainometer 2 and circular multi-functional wiring sheet 3 all design and make according to unit independently.Outer ring strainometer 1 be an external and internal compositions with inner ring strainometer 2, and the two is bonded on the circular multi-functional wiring sheet 3, binds, lamination, and is superimposed and form a whole, and is welded with the circular full-bridge strain ga(u)ge of formation behind the extension line on the circular multi-functional wiring sheet 3.
During use, circular full-bridge strain ga(u)ge directly is affixed on the sensor and uses, and need not to add in addition lug plate, simplifies strainometer making and use occasion operation.
Claims (2)
1. a circular full-bridge strain ga(u)ge is characterized in that, external and internal compositions is counted in outer ring strainometer and inner ring strain, and the two is bonded on the circular multi-functional wiring sheet, forms a whole through pressing, is welded with extension line on the circular multi-functional wiring sheet.
2. circular full-bridge strain ga(u)ge according to claim 1 is characterized in that, described outer ring strainometer, inner ring strainometer and circular multi-functional wiring sheet are unit independently before pressing.
