Pressure sensor contains the just adjacent constitution regular triangle of head and the tail in the device of three elastic equilibrium roof beam, has eliminated and has placed the vibration that arouses because of weighing the thing, can be stabilized the registration fast, and 3 times range has been extended according to the adjacent method installation of constituteing regular triangle of head and the tail on the one hand to three elastic equilibrium roof beam, and on the other hand more is favorable to stable in structure and even atress because constitute a plane at 3 for measurement accuracy obtains further improvement.
Description
Technical field
The utility model relates to a kind of apparatus for measuring quality, specifically relates to a kind of electronic scale.
Background technology
Electronic scale is the important component part of modern measure system, and high-precision electronic claims to be widely used in the occasions such as commerce and trade, scientific research and industry.But during high-precision weighing, weight is placed on the body vibration that weighing plate can cause weighing plate, the vibration of weighing plate can cause registration unstable, need to wait for that the long period could stablize reading, because high-precision electronic weighing journey is less, in practical operation, there is maloperation, elastic equilibrium beam generation inelastic strain can be made, thus produce comparatively big error.
Summary of the invention
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of electronic scale.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of high-precision electronic claims, and comprises guard collar, weighing plate, three pads, one, three pads, two, three pads three, three pressure transducers, base, power supply and registration devices.Be provided with control module in described base, registration device, guard collar are arranged on base, and power supply is arranged in base, the control module electrical connection respectively of described registration device, power supply; The below of described each pressure transducer arranges a pad two and a pad three, pad two is connected with base and pressure transducer respectively, pad three is arranged on base with bottom pressure transducer exists gap, and the top of each pressure transducer is provided with a pad one; Described three pressure transducers are all electrically connected with control module, and the upper end surface of three pressure transducers is in same level; Described weighing plate is arranged on the top of three pads one, and contacts with three pads one.
Described pressure transducer comprises elastic equilibrium beam and be arranged on straingauge on elastic equilibrium beam, described in be pasted onto elastic equilibrium beam centre position.
The adjacent composition equilateral triangle of described three pressure transducers head and the tail.
Described guard collar is that organic glass is made, its internal diameter 120mm, external diameter 130mm, height 50mm.
Described weighing plate makes with organic glass, its radius 59mm, thickness 5mm.
Described pressure transducer is N430 type pressure transducer, its long 80mm, wide 12.7mm, high 12.7mm.
Compared with prior art, the beneficial effects of the utility model are:
1, by the combination of three N430 type pressure transducers, pressure transducer comprise three elastic equilibrium beams and in device the adjacent composition equilateral triangle of head and the tail, eliminate the vibration that causes because weighed object places, stable registration can be obtained fast.
2, three elastic equilibrium beams are installed by the method for the adjacent composition equilateral triangle of head and the tail, expand the range of electronic scale, on the other hand because 3 form a plane, are more conducive to Stability Analysis of Structures and uniform stressed, measuring accuracy is further enhanced.

Fig. 2 is the cut-open view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figures 1 and 2, a kind of high-precision electronic claims, and comprises guard collar 1, weighing plate 2, three pads one 3, three pads 24, three pads 35, three pressure transducers 6, base 7, power supply 8 and registration devices 9.
Be provided with control module in described base 7, registration device 9, guard collar 1 are arranged on base 7, and power supply 8 is arranged in base 7, the control module electrical connection respectively of described registration device 9, power supply 8; The below of described each pressure transducer 6 arranges a pad 24 and a pad 35, pad 24 is connected with base 7 and pressure transducer 6 respectively, pad 35 is arranged on base 7 with bottom pressure transducer 6 exists gap, and the top of each pressure transducer 6 is provided with a pad 1; Described three pressure transducers 6 are all electrically connected with control module, and the upper end surface of three pressure transducers 6 is in same level; Described weighing plate 2 is arranged on the top of three pads 1, and contacts with three pads 1.
The straingauge 11 that described pressure transducer 6 comprises elastic equilibrium beam 10 and is arranged on elastic equilibrium beam 10, described straingauge 11 is pasted onto elastic equilibrium beam 10 centre position, by changing the quality of measured weight, straingauge 11 is occurred change that deformation is converted into resistance, and then quality is presented on registration device 9.
The adjacent composition equilateral triangle of described three pressure transducers 6 head and the tail.Weighing plate 2 and base 7 are fixed with elastic equilibrium beam by pad 1 and pad 24 respectively, prevent electronic scale entirety from deforming.
