A disposable container requires no washing after each measurements.This makes it possible to safely measure even on site where no glassware is allowed.• VISCO Package: Package A• Disposable container can be purchased independently.Compact and Easily Carried with One HandVISCO's sleek dimensions and weight (main unit: 12x12x20cm, 1.2kg) make it compact and easily carried with one hand.The instrument's legs can be folded up, making it further compact and allowing for even greater storage capabilities.Measurement screenLevel adjustment screenOperation requires only one dial button. All operations can be performed with the simple act of "sliding" or "pushing" the dial button. No more accidental operations due to pushing the wrong button.Measurement preparation can easily be done with just one hand. Place the beaker underneath the pre-set area and place the instrument on the stand. No troublesome height adjustment necessary.VISCO is very easy to set-up. The spindle can be attached with just "one touch" —simply insert the spindle in the instrument. Absolutely no complicated set-up required.Uses Only 1/33 of the Standard Sample AmountStandard measurement instruments for viscosity require a large amount of sample (500mL). VISCO is capable of taking measurements with just 15mL of sample. This is roughly 1/33 of the standard sample amount. Measurement can be done with only a small amount of sample, resulting in less waste of valuable sample and a significant reduction in cost.Quick Measurements AnywhereNot only does VISCO run on AC power, but it can also operate on battery power. This allows formeasurements to be taken anywhere, even in places lacking a power source. The instrument can also be placed directly on the beaker, making it possible for quick and simple measurements to be taken.No need to establish a specific location for measurement — with VISCO, you can take measurements anytime, anywhere.Easy to Read,Fully Digital DisplayA fully digital display allows for anyone to quickly and easily read results.The simple display is easily and readily understood.Never Take Any Glassware (on site) Ever AgainATAGO: Creating the Perfect Fusion of Innovation, Technology and SimplicityONE TOUCH ™, ONE HAND ™ and ONE BUTTON ™.Presenting the VISCO, a brand-new way of measuring viscosity with 3 simple “ONE’s.”Roughly331P.4P.8Package APackage BMeasurement MethodsVISCO has several measurement methods.Select the measurement method most suitable for your application and conditions.VISCO APPLICATIONFood and BeverageBeverages (e.g. juice, etc.)Viscosity is critical parameter in beverage manufacturing, from the production phase all the way until the product reaches consumers.MilkIn regards to milk, aside from whole milk (3.25%), there is reduced fat milk (2%), low-fat milk (1%) and nonfat (skim) milk. In general, nonfat milk has the lowest viscosity.Tomato Juice /PuréeTomato juice or purée must always flow through the production line under a constant, homogenized state.Viscosity management is indispensable to this process.SauceThere are many kinds of sauce. These include (in ascending order of viscosity): Worcestershire sauce,thicker Worcester sauce and pork cutlet sauce. In Japan, there are approximate levels or grades for viscosity determined by JAS.KetchupKetchup, a pseudoplastic fluid, is characterized by its propensity to remain in its bottle even when turnedupside-down. Applying a bit of force (squeezing) to the bottle causes the ketchup to flow out. It is also known for reacting differently at varying temperatures.MayonnaiseMayonnaise also remains in its bottle, even when turned sideways or upside-down and maintains high viscosity. The greater the force applied, the easier it will flow out and the viscosity will decrease.Olive OilThere are many vegetable based oils that are Newtonian fluids (a fluid that does not change viscosity even when force is applied). Olive oil is a Newtonian fluid.HoneyHoney is a Newtonian fluid. Its viscosity is not affected by force and speed. Only temperature can cause a change in viscosity.JamImagine spreading jam on a piece of toast. The jam easily glides across the toast. Viscosity is a crucial factor in making jam spreadable. Managing the viscosity can be quite difficult, as jam contains solids.YogurtNumerous factors throughout the manufacturing process, such as how much fat is left in the yogurt, pasteurization and pH management affect the final product and texture (viscosity).Butter /MargarineButter is a Bingham plastic (a type of non-Newtonian fluid). It can not flow unless some degree of force isapplied, but applying force past a certain degree cause it to become more malleable in proportion to the force.Japanese Curry (curry roux)Thickened curry (roux) is quite mainstream in Japan. Thickened curry is made by applying heat to flour, which changes it into a more paste-like consistency, resulting in an increase in viscosity. Even in the final processing stage of being sealed into a retort pouch, the curry roux must maintain the same viscosity to allow the same amount to extrude every time the same amount of force is applied.Gelatin /AgarViscosity measurements can be used to check and manage the gelling process of gelatin or agar. However, if the gelatin or agar completely solidifies during viscosity measurement, a spindle-shaped gap will form, preventing measurements from being taken.Household EssentialsToothpasteToothpaste with a paste-like consistency is a Bingham plastic. It will not flow out unless the tube is squeezed. It is important for toothpaste to be at optimal viscosity. After applying the appropriate amount onto atoothbrush, toothpaste at just the right viscosity will break cleanly from the tube and retain its shape without flattening.Using a disposable containerPlacing the instrument directly on the included beaker Using the included stand and beaker(Worcestershire sauce, thicker Worcester sauce, pork cutlet sauce, etc.)VISCO PackageUsing disposable containers eliminates the hassle of cleaning after measurement.Package A, which includes a specialized adapter for use with disposable containers such as paper cups, is available at ATAGO.• Cat.No.6810·VISCO™ (main unit)·Cup Adapter (with 100pcs cups*): RE-78141• Cat.No.6830·VISCO™-895 (main unit)·Cup Adapter (with 100pcs cups*): RE-78141* 50pcs of paper cups and 50pcs of plastic cups are included.Cup adapterMeasurement of low viscosity (1 to 2,000 mPa·s) is possible.A package that comes with Ultra Low Adapter (ULA) for measuring low viscosity sample and VISCO (main unit) i s available.●Cat.No.6811·VISCO™ (main unit)·Ultra Low Adapter (ULA): RE-77120●Cat.No.6831·VISCO™-895 (main unit) ·Ultra Low Adapter (ULA): RE-77120Cup adapter setup exampleGelatinPre-dysphagia dietPolysaccharides (as thickening agents)Thickening agents Starch AgarDysphagia dietThick (viscous) Food MeasurementVISCO—Thickness MeterIn recent years, Japan has faced an ever increasing, aging population. "Longevity" isn't the only point of discussion — how to extend good health throughout life expectancy and what defines QOL (Quality of Life) have also become hot topics.Food is of course fuel for life. We essentially "eat to live," but food holds greatersignificance. Food can also bring us joy as a source of pleasure in our lives. Food consistency is an important component that impacts the quality of life for individuals that have difficulty in chewing and swallowing (dysphagia). VISCO can assist in managing food consistency, thereby improving the quality of life.The Importance of Thickening FoodA common misconception found among dysphagia diets and care facility diet plans is thickening food /drink (by grinding, pureeing, mashing, chopping, or mincing) makes it easier to swallow.In reality, thickening food reduces the flow of the substance, and on the contrary, it becomes rather difficult to swallow.If this is the case, then just why is it important to thicken food?Individuals with dysphagia (an affliction characterized by the failure in the automatic process of closing the respiratory tract to allow food to pass through the esophagus) need more time when swallowing to allow food to properly pass through the esophagus. Thickening food and beverages is effective in preventing food from accidentally passing through the respiratory tract.Enhancing the Way Food is ExperiencedIn the past, dysphagia diet assessment was based solely on "hardness," but recently, it has become common to assess dysphagia diets based on 3 criteria: hardness, cohesion (ease of clump formation) and adhesion (smoothness).There was also a time when the focus was on determining the best way of intaking food to absorb the most nutrition.Nevertheless, if you don't look forward to your meals or derive any enjoyment from eating in the first place, you may gradually stop eating much of anything. Flavor isn't the only aspect to consider; food texture (mouthfeel) is also regarded with great importance.Until now, from a number of standpoints such as cost, space (installation) and operation, large sized viscosity measurement devices and expensive texture meters were utterly ill-suited for personal use and for small-scale care facilities.VISCO is compact, lightweight and portable, making it ideal for hospitals, care facilities or household use. It can quickly and easily measure and assess the textual properties (thickness) of foods for dysphagia diets and care facility diet plans. Using VISCO, anyone can look forward to savoring and enjoying safe, nutritious food.Dysphagia Diet PyramidShampoo and CoditionerConditioner must have a particularly high viscosity, as it coats every single stand of hair. The components used in shampoo and conditioner may not mix well, but adding viscosity ensures that they are evenly maintained.CosmeticsViscosity measurements and research in the rheological properties of cosmetics is conducted in order to give even slightly viscous cosmetics a smooth, light, easily spreadable quality when applied.Industrial /ChemicalAdhesivesThere are many types of adhesives for different purposes and applications. For example, structural adhesives include general adhesive for temporary bonding, gap-filling adhesive and adhesive used for coating purposes. Gap-filling adhesives: properties, such as bond strength, leveling (smoothness) and ease /difficulty of flow are assessed through viscosity measurements.Water glassWater glass is also commonly known as, "Sodium silicate." It is often used in soaps and adhesives. It is also used in a wide variety of fields, such as engineering, paper manufacturing and pharmaceuticals. Water glass has an extraordinarily high viscosity.Resins /PolymersVarious kinds of resins and polymers have appeared in recent years. In addition to ascertaining their properties, viscosity assessment is also an absolute must.Photopolymers (used in 3D printing)With the spread of 3D printers, photopolymers have suddenly gained traction in the global market. When photopolymers are exposed to light and heat, their viscosity increases and they harden.Paint /Pigment /Varnish /InsulatorsPaint (brush application): good brushability and drip-resistant. Tends to have a low viscosity under a high-shear rate and high structural viscous properties under a low-shear rate.Spray painting (coating): types of spray painting include air spray painting, airless spray painting and electrostatic coating. Most air spray paints have the same structural viscous properties as paint for brush applications. Airless spray painting and electrostatic coating is utilized in applications such as the final coating in automobile painting. As such, great emphasis is placed on the appearance and finish of the paint. Compared to paint for brush applications and air spray paint, most airless spray paints have a low viscosity, with similar properties to Newtonian fluids. The leveling of the paint after it's applied affects the overall appearance of the finished products.Electrodeposition (electrophoretic deposition): used for applying coatings to complex shapes /objects.Through electrodeposition, a film of coating is created on the surface of the target object. The object undergoes a baking or drying process, which makes the surface become smooth. This (leveling) is an extremely critical part of the process. It is necessary to use paint with viscosity sensitive to temperature.GlycerinGlycerin is highly viscous and it's a great moisturizer. It is often added to cosmetics to increase theirmoisturizing properties. It is also used in various food products as a thickening agent and as a humectant in pharmaceuticals.Hydraulic FluidsThe viscosity of hydraulic fluid tends to decrease as the temperature rises. If the viscosity decreases too much, it may lead to deterioration in the lubricating properties of the fluid and adversely affect pump efficiency. Incontrast, viscosity tends to increase as the temperature decreases. this can increase the usual amount of force needed to operate the pump, and may accelerate wear and tear. This is why you must select a hydraulic fluid with the optimal viscosity for your application.LubricantThe viscosity of lubricant is a vital element, of which the life span is affected by the wear and tear of machinery. Depending on the viscosity, if too much heat is generated, the life span of a lubricant may be reduced. Not only does this increase costs, it also shortens the life span of the machinery. This is why managing the viscosity of lubricant is of the utmost importance.Cutting FluidsA lot of heat is generated during machining processes. Cutting fluid has a low viscosity, which makes it well-suited for effectively dissipating heat. Low viscosity is also necessary for facilitating circulation andeliminating impurities. However, to ensure precision and control when spraying or coating, the viscosity must not be too low. Managing the viscosity of cutting oil is essential.Slurry/Ceramic Slurry (ceramic mold casting)"Slurry" indicates a fluid which contains solid, suspended granules. Due to its properties, if it not mixed, it may precipitate. Viscosity management is critical for ensuring a smooth transition.Omoyu gelatin (rice broth based gelatin), Kayu (rice gruel), Gelatin kayu (gelatin based rice gruel), Mochi (Japanese rice cake made of mochigome, a short-grain japonica glutinous rice), Negitoro (the fatty flesh of tuna minced to a paste and mixed with chopped green leaves of Welsh onions), Chawanmushi (a cup-steamed egg custard hotchpotch), Foie gras (a food product made of the liver of a duck or goose that has been specially fattened), Mizuyoukan (a thick, soft jellied dessert made of red bean paste, agar and sugar), Koshian (boiled, mashed sweet red bean paste), Kabocha (Japanese pumpkin; a variety of winter squash of the species Cucurbita maxima), Shiitake (a variety of edible Japanese mushroom), Gomokumame (a Japanese dish consisting of cooked soybeans with various vegetables), Hijiki (a type of edible seaweed; Hizikia fusiforme)。

激光测速枪的原理

激光测速枪的原理

激光测速枪的原理雷达测速枪自上世纪50年度应用至今有60年历史了。

但从上世纪末,在欧美越来越多的交警开始采用激光测速枪来代替雷达测速枪。

激光测速枪向汽车发射一束激光,然后测算物体将激光返回的时间,从而计算出物体与发射点的距离。

与雷达测试枪不同的是,激光测速枪不是通过测速发射回来的波形频率的变化来计算速度。

激光测速枪在极短的时间内,发射出很多束激光,然后测算出不同激光束反射回来的时间,来计算汽车的距离变化。

由于激光枪在极短时间内将(毫秒级)即可以测算出几百次,因此,对汽车移动的速度计算非常准确。

传统的雷达测速枪比较容易被雷达测速预警仪(电子狗)探测到。

一套简单的测速预警仪就是一套雷达信号接收装置,就好像收音机接收FM和AM无线信号一样。

我们身处的空气中充满了无线信号。

从电视广播信号、电台信号、自动门探测器等等。

不同的信号接收器能有选择性的接收到不同的信号。

无线收音机接收AM 和FM信号,而雷达测速预警仪(电子狗)探测警察的测速雷达信号。

与无线广播不同的是,无线电台的频率不会轻易调整,但是,交警部门将不定期的调整其雷达测速枪的频率,而预警仪厂家也在不停的发明新的预警仪以对付警察叔叔的挑战。

如果交警叔叔跟在你的车后面用雷达测试仪抓捕你,一台普通的雷达测速预警仪(电子狗)就帮不了你的忙了。

在这种情形下,当你的预警仪发现雷达信号时,警察已经锁定了你的车速。

当然,大部分的情况是,一台与时俱进的雷达测速预警仪(电子狗),能在交警抓捕你之前提醒你雷达测试枪正在瞄准你。

因为,一般来讲,交警会长时间的将雷达测速枪打开,等待你的落网,而不是看到你的时候、他才跟在你后面瞬时开启雷达测速枪。

到目前为此,全世界的交警部门拥有了多达几十种雷达测速设备。

其频率范围跨度很大,大致包括X频10.250GHZ:±150MHZ、KU 频12.270±150MHZ、K 频23.6GHZ ~24.3GHZ、KA 频34.1GHZ ~35.9GHZ。

2 功能特色
Labasys 测试设备定位于工艺装置中的在线监测,在高温高压环境、颗粒的黏附作用、浓度标定、数 据处理等方面都独具特色,保证设备能够在复杂恶劣的工业装置中能够安全、稳定的运行。
高温冷却系统
在工业设备中,工艺流程中温度往往较高,例如循环流化床锅炉、流化催化裂化工艺等。为保证设备 能够在高温环境中正常使用,MSE Meili 公司为 Labasys 设备开发了冷却系统,用于保护设备正常运行。 循环冷却水系统可对探针进行降温,保证探针组件不会受到高温影响;气冷系统对电子元器件进行保护, 杜绝了高温危害,可在超过 1100℃的环境中进行长时间的测量。
清洗单元
当粉末比较潮湿,或者颗粒粒径较小易受静电等影响时,从而造成镜头前粉尘的黏附,影响数据的准 确性。 MSE Meili 公司针对该问题, 开发了自清洗单元, 通过向镜头前泵入高压的惰性气体, 对镜头进行吹扫, 保证粉尘不会累积到镜头上,从而避免了测试结果的偏移。
标定装置
颗粒浓度的准确测量取决于标定数据的精度。为了快速获得 准确的标定数据,Labasys 测试系统配备有专门的标定装置,该 装置包括质量流量计、气体流量计、颗粒分布板、测试管段等重 要组件,可制造均匀的颗粒分布环境,并根据颗粒和气体的流量 计算浓度,获得精确的标定数据。
Labasys 测试系统
Labasys 测试设备通过流场内的颗粒、液滴或气泡 对激光产生反射,对反射的激光信号进行收集,反射光 越强则浓度越高。通过标定可以获得颗粒浓度与反射信 号强弱之间的对应关系,在实际测量中,通过与标定数 据进行对比即可获得颗粒的浓度信息。 反射光信号的波动记录了颗粒群的信息,通过对相 邻两个或三个探头获得的信号进行相关性分析,结合探 头之间的位置,即可计算颗粒的运动速度。

气液固三相测量
激光在遇到气固、 气液、 液固等壁面时, 均会有反射光, 但是不同的相界面对激光的反射程度不同。 例如, 在气液固三相系统中,颗粒表面对激光的反射较强,而气液界面(即气泡表面)因有一部分光投射出去而 导致反射光较弱。根据三相系统中不同界面对光的反射信号不同,可以采用激光反射技术对系统中颗粒和 气泡的信息进行全面的分析。 采用 Labasys 对气液固三相系统进行测量,获得的原始信号如下图。分析原始电压信号,信号值主要 在一定值附近波动,同时也存在着波谷。对三相系统反射激光的过程进行分析,可以认为信号的波谷是由 气泡的界面反射激光所致。因此,可定义一个过滤值,将颗粒与气泡反射形成的信号区分开,分别进行分析。 在将颗粒和气泡的信号分开之后,可分别获得颗粒和气泡的运动速度和浓度。同时,气泡产生的信号 波谷的时间跨度可表示气泡经过探头的时间,再结合气泡的运动速度,可计算出气泡沿流动方向上的尺寸。
Labasys 100
Labasys 100 是 Labasys 测试系统的最 基本配置,能够满足同时测量速度和浓度的 需求,采用普通不锈钢探针。可选择 2 或 3 个探头,分别对应 1 维和 2 维速度的测量; 根据不同的测量环境,并可选择配置清洗装 置、冷却设备以及 Flex 探针等,能够更好的 适应工业装置和实验室设备上的应用。 所有的镜片和电子器件都集成在轻巧、易 于操作的设备中; 采用模块化设计,可以灵活地适应不同的 工作环境和测量任务,也可随意更换组件; 对流场扰动小,灵敏度高,精度高; 同时测量浓度和一维或二维速度; 定制的设备连接阀实现高压下的安装与拆 卸; 高效的清洗单元避免静电黏附的影响。
