Abstract
The utility model discloses an annular resistance strain gauge which comprises a base and sensitive grid bars, wherein the base is annularly platy, the upper end surface of the base is adhered with two or more than two strip sensitive grid bars, the sensitive grid bars are arranged in an encircling way at equal intervals on the same plane, and the curve form of each sensitive grid bar is an Archimedes spiral line. The annular resistance strain gauge is a molded whole body and can be directly, conveniently and quickly adhered on an elastic body of a sensor with a torsion circle structure and corresponding size, the antijamming capability of the strain gauge is strong, the influence from lateral force is small, and the strain gauge is uniform in sensing strain change and can accurately transfer true strain, thus providing necessary conditions for the sensor with the torsion circle structure to reach C3 level or C4 level or the higher precision and the high stability.
Description
Technical field
The utility model relates to a kind of strain ga(u)ge, and what be specifically related to is a kind of ring resistance strainometer.
Background technology
Along with the continuous development of strain ga(u)ge and electronic weighing technology, people are higher to index requests such as the precision of strain gauge transducer and stability.Because strain ga(u)ge is the core parts of strain gauge transducer, so strain ga(u)ge is required also to improve thereupon.The pattern of strain gauge transducer is a lot; A kind of sensor (Ring Load Cell) that is called loop formation is wherein arranged; This sensor is mainly being used morely aspect the electronic-weighings such as electronic vehicle weighing apparatus, vapour inspection line, bunker scale, have precision height, easy for installation, dependable performance, can hermetically sealedly weld, characteristics such as grease-proof and waterproof.But; Because the sensor of loop formation is to reach the position in order at surface of elastomer to paste a plurality of strain ga(u)ges or a synthetic integral body of a plurality of circulating type Strain Meter Set at present; In practical application, this sensor construction complex design, the combination quality of pasting a plurality of strain ga(u)ges can not guarantee; Accurate location difficulty; Connection resistance influence is bigger, directly causes a series of problems such as transducer sensitivity dispersion, non-linear increase, temperature performance be relatively poor, can't satisfy more high precision, the more loop formation sensor requirement of high stability.
Summary of the invention
The purpose of the utility model is to provide a kind of ring resistance strainometer that can directly be attached on the loop formation sensor elastomer, to overcome the above-mentioned defective of existing in prior technology.
The technical scheme that realizes above-mentioned purpose is: a kind of ring resistance strainometer; Comprise substrate and responsive coral; Said substrate is the annulus sheet; The upper surface of substrate is pasted with banded responsive grizzly bar more than two or two, and all responsive grizzly bars are at grade equidistantly around arrangement, and the curve form of every responsive grizzly bar is a spiral of Archimedes.
Said every responsive grizzly bar is provided with 1～4 zeroing grid in the approaching position of a termination solder joint separately.
The advantage of the utility model is: as the integral body of a typing; Can directly be attached to quickly and easily on the elastic body of the corresponding loop formation sensor of size, avoid a plurality of around problems such as location out of true, quality that the strainometer occasional combination produced can not guarantee.This strainometer antijamming capability is strong, and it is little influenced by side force, and it is even to experience STRESS VARIATION, can accurately transmit logarithmic strain, for the loop formation sensor reaches C3, C4 level or more high precision and high stability provide necessary condition.

Fig. 2 is the A-A cut-open view among Fig. 1.
Among the figure: 1. substrate, 2. sensitive grid, the 3. first responsive grizzly bar, 31. zeroing grid, 32,33. solder joints, the 4. second responsive grizzly bar, 41. zeroing grid, 42,43. solder joints.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As depicted in figs. 1 and 2; The utility model ring resistance strainometer comprises substrate 1 and responsive coral 2, and substrate 1 is a kind of annulus sheet made from materials such as synthetic resin or engineering films; The upper surface of substrate 1 is pasted with two responsive grizzly bars; Promptly the first responsive grizzly bar 3 and 4, two responsive grizzly bars 3 of the second responsive grizzly bar and 4 are spiral of Archimedes form location with separately curve form at grade, each other equidistantly around.There is a solder joint termination of every responsive grizzly bar, on the first responsive grizzly bar 3, is provided with zeroing grid 31 near the position of a termination solder joint 32; On the second responsive grizzly bar 4, be provided with zeroing grid 41 near the position of a termination solder joint 42.
In the utility model sensitive grid what with the zeroing grid what can confirm according to the sized and the set of applications bridge mode of strainometer; Be generally, the strainometer of 120 Ω-1000 Ω specification is with two responsive grizzly bars, and the zeroing grid on every responsive grizzly bar are one; The strainometer of 1000 Ω-4000 Ω specification is with two to four responsive grizzly bars, and the zeroing grid on every responsive grizzly bar are two; The strainometer of the above specification of 4000 Ω is with responsive grizzly bar more than four, and the zeroing grid on every responsive grizzly bar are two to four.
