<h1>Viscosity control of product quality and process control</h1><strong> Author: <a href='http://www.articleseen.com/profile_Viscometer.aspx'>Viscometer</a></strong><br /><p>Viscosity of the product quality and process management control is a crucial aspect of the production of coatings industry. As a supplier to focus on customer satisfaction and product consistency, viscosity becomes important to assess and directly affects the cost-effectiveness and quality of most processes. Coatings industry, viscosity, questioned the process engineers and quality control departments, because it can be influenced by physical variables of temperature and shear rate measurements. In addition, embedded OEM applications, for example, refuse stations faucets solvent or mixture of strength, it is necessary to provide value-added features continuous monitoring of viscosity. Viscosity of the management consumable coating can save while at the same time reducing process downtime. Historically been used expensive and inflexible mechanical products. Up to now, been no viable "electronic" means the viscosity, and processors were forced to measure low, or use different methodologies to repeat the cost / benefit trade-off. BiODE ViSmart ™ acoustic resonance of electronic-based viscosity sensor and measurement systems are changing all of this product and solution-oriented coatings industry. BiODE ViSmart sensor system (see Figures 1 and 2) to measure the viscosity of from 0 to 100,000 CP range (larger ranges may be measured and is financially dependent) with a ± 1% repeatability of environment working temperature from -20 ° C to 135 ° C. . ViSmart sensor has no moving parts used in semiconductor technology and keep it sealed, four-ounce package. ViSmart sensor measures the temperature at the same time, which facilitates customers with a single temperature measurement device. Coatings industry is familiar with the kinematic viscosity (centistokes) and the dynamic or absolute viscosity (centipoise), which are related as centistokes = centipoise / specific gravity. BiODE measure viscosity introduces a third class, known as acoustic viscosity. Acoustic viscosity of 2 centipoise units of specific gravity. Knowledge of specific gravity allows the conversion between these three units fixed shear rate and temperature. This method employs the measurement of viscosity of the liquid in contact with the shear acoustic wave resonator. Fluid viscosity leads to thick liquid layer is hydrodynamically connected to the surface. Determined by acoustic resonator caused by the viscously entrained fluid loading entrained film thickness and density. Acoustic viscometer response is proportional to the viscosity of the product of density and radian frequency of vibration (kg2/m4) low-frequency limit. Acoustic wave resonator supports a standing wave through its thickness. Wave pattern interacts with electrodes on the lower surface (sealed from the liquid) and interacts with the fluid on the upper surface. Most of the liquid does not sound signal, and a thin layer (microns or micro inches to) move the vibrating surface (oscillation amplitude of one atomic spacing, that). Measure can be immersed in the liquid, and as little as 100 liters, may also take a drop of the sample. BiODE sensor size is about 2 0.3 1.1 2 1.3 (smaller than a matchbook). BiODE system is essentially on the network (including wireless data communication settings), and allows the data analysis system is not physically connected to the sensor computer. BiODE system is easily expandable distributed process control and portable field measurements. Measurement information screen at once and continuously, and a marked improvement over current technology (see Table 1). Most of the existing line viscometers are big and bulky, and the response is slow and inaccurate, but a lot of difficulties in measuring units of fluids with high or variable shear rates. They also clean and operational tasks, and usually only provides analog outputs and is therefore difficult to link modern process control equipment, which agrees with the flexibility of digital inputs. BiODE digital design advantages is that the nature of much smaller, faster, durable and reliable, much lower cost, and scalable than existing products. Its design is more flexible than existing systems and facilitate access to a wide range of process control devices, because it outputs a digital rather than analog signals. Process measurements ViSmart can be mounted directly behind a series of applications for the reactor vessel, or some specific customer order potential flow tube (see Figure 3, one example of the embedded flowcell installation).</p><strong>About the Author:</strong><br />Visit viscometer.co for all types of <a rel="nofollow" href="http://www.viscometer.co/">viscometer</a> according to your need.<p> Article Source: <a href='http://www.articleseen.com/Article_Viscosity-control-of-product-quality-and-process-control_115496.aspx'> http://www.articleseen.com/Article_Viscosity control of product quality and process control_115496.aspx</a></p>
