Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.
As shown in Figure 1, a kind of accurate weighing device that is used for mental package liquid comprises base plate 5; Be fixed with briquetting 7 on the said base plate 5; Be connected with support lever 6 on the said briquetting 7, respectively be provided with a support portion 10 on the base plate 5 of said support lever 6 two ends correspondence, said briquetting 7 also is connected with an end of LOAD CELLS 8; The other end of described LOAD CELLS 8 is fixed on the support lever 6, and said LOAD CELLS 8 is connected with control system through signal wire 9.
Above-mentioned two support portion 10 end faces and two support lever 6 bottom surfaces all have at interval, and the distance at the interval of these two positions is consistent.
Above-mentioned briquetting 7 is near one of them support portion 10.
Each above-mentioned 10 corresponding base plate 5 below, support portion are provided with a feet 11.
Above-mentioned control system comprises A/D converter and microprocessor, and said signal wire is connected with A/D converter, and A/D converter is connected with microprocessor again.
Above-mentioned support lever 6 is a flexible member.
When weighing; Tripping piece 7 nearer support portions 10 obtain stressed; Make support lever 6 distortion, briquetting 7 produces the simulating signal that downward pressure produces greater than zero load LOAD CELLS 8, after signal wire 9 collections and the A/D conversion; Draw the actual weight data of placing thing, technological unit and index are handled by microprocessor.
As the concrete application of above-mentioned accurate weighing device, below for a kind of use above-mentioned accurate weighing device detector:
As shown in Figure 2, a kind of liquid detecting instrument that is used for mental package comprises housing 1, and the bottom in the described housing 1 is provided with accurate weighing device 3, and said accurate weighing device 3 is provided with and detects bucket 2.
Above-mentioned housing 1 below is provided with four fixing feet 4, and said accurate weighing device 3 is arranged on wherein the bottom in two fixing feet, the 4 top corresponding shell 1.
Use with concrete for this Design of device principle, simply describe below:
Different liquids has different density, is about 1g/ml like the density of water, and the density of inflammable and explosive dangerous liquid is generally less than about 1g/ml, and mental package beverage density is greater than water.According to physics mass formula m=ρ v, wherein m is the object quality, and ρ is an object density; V is an object volume, and certain like same can drink volume v, the density of water is 1g/ml; And the density of 93# gasoline is about 0.725 g/ml; Their density p is different, and the quality m of its object is just different, has the otherness of quality.The mental package beverage of selling on the market that do not break a seal has fixing gravimetric value; As other liquid that changes the outfit therein then its gravimetric value must be different; Utilize this proportion characteristic to solve the problem that electromagnetic wave can't penetrating metal, be undoubtedly a kind of quick, easy method.
At first in internal memory, deposit the common not mental package liquid weight in Kaifeng in market in, and do pictorial symbolization; Secondly in the actual measurement process; After detecting metal object, flow process changes metal detection branch over to, from internal memory, accesses the mental package liquid graphics data tabulation of preserving in advance; Select identical pictorial symbolization; As long as error range is within 5% between pre-stored values and the measured value, then show actual measurement liquid be and prestore liquid phase with, can be considered safe liquid.
The instrument common mental package beverage gravimetric value that do not break a seal that before detection, prestores earlier; In the actual measurement process; Seized mental package beverage gravimetric value and pre-stored values are selected comparison, exceed the seized dangerous suspicion of mental package beverage that do not break a seal of then thinking of error range, instrument sends alarm.
In the actual measurement process at the scene, be the situation that can not cause safe liquid wrong report or dangerous liquid to fail to report with upper type.
Various metal packaged beverages are arranged on the market, and like iron or aluminum etc., the method for this metal value that prestores makes material eliminate its influence, and all kinds of metal can dixie cups can be measured, can be because of the different phenomenons that produce wrong report or fail to report of material.And pre-stored values can so that all kinds of as: liquid of different nature such as cola, peanut milk, cold tea, mixed congee are to be detected accurately.
