Viscosity of a fluid which is deformed or shear stress or stress resistance tool. Times daily (for liquids), viscosity of the "thickness". Various methods have been invented for measuring viscosity. Each of these methods are selected and used in industry, where most appropriate. However, the application of viscosity measurements have recently expanded into new areas, such as measurements of polymer solutions, adhesives, coatings, abrasives, engine oil, biodiesel fuel, and even soft drinks, cosmetics and human blood.

Meanwhile, demand is increasing measurement system that can reduce the energy bottleneck of the sample liquid, for example, rotary power and barycentric shift to measure the viscous property, which is an integral part of the liquid. In addition, there are requirements for continuous monitoring of a wide range of viscosity to viscosity change caused by temperature change, and curing the adhesive agent, etc.
Reply to this challenge, the A & D Company Ltd, Japan introduced a new technology, ie, a tuning fork vibration method for measuring viscosity in accordance with the above requirements.
Recently developed a tuning fork vibration viscometer not only understood the reduction and cost-reduction measures, but also made it possible to perform a wide spectrum of continuous measurements of 0.3 MPa (the equivalent of acetone) to 10,000 mPa.

More recently, the measurements as small as 2 ml of liquid sample was possible, including the application of such fluid viscosity measurements to resist color liquid crystal, and human blood. High-quality tuning fork vibration viscometer rapidly expand its scope of application of viscosity measurements to be impossible. Meanwhile, the quality control requirements for offshore production, accuracy and ease of tuning fork vibration viscometer was also to gain the attention level of output.
Sine wave Vibration Viscometers & D in India, a subsidiary of A & D Company, Japan, the well-known name of test and measurement devices. A & D Vibro viscometer sample unit detected by the sensor consists of two thin plates to vibrate, as shown in the above viscosity. It driving the sensor plate to vibrate the same sine wave vibration of reverse-phase, as the tuning-fork.Measuring viscosity with sinewave Vibro viscometer-3.jpg
To suit the measurement system, the sensor plate to operate the electromagnetic force at the same frequency as the resonance, which is characteristic of each structure. The most prominent resonance in this viscometer.
When the detection device vibrates, it produces large-scale reaction force sensor plate unit during the spring plates. Each sensor plate reverse drive before the next stage, while the vibration frequency and amplitude in order to eliminate the reaction force. This enables one to obtain a stable sine-wave vibration.
Electromagnetic drive unit controls the vibration sensor plate equal amplitude of the sample using a detection device resonance. Driving electric current, as attractive force is found as a viscosity between the sensor plate and the sample size. Viscosity coefficient of correlation between the driving electric current and the viscosity of the scale.
Resonance detection unit allows determination of the viscosity with a high sensitivity to a lower viscosity ranges, and also effectively acquire only a small amount of electric current driving force.
Thus, it is possible to measure viscosity while maintaining a wide dynamic range and high resolution. The newly created SV method (tuning-fork Vibration Method) achieved accuracy, repeatability, as high as 1% of Reading viscosity measurement. There is no need to change sensor plates during continuous measurement. This differs from the rotational viscometers, which requires several types of rotors and continuous viscosity measurement disturbance and loss of exchanging them.
SV series is also equipped with WinCT Viscosity, Windows Communication Tools Software. WinCT the viscosity, you can create a real-time graphs of viscosity and temperature data.
In addition, the boost function is available and the logarithm of the screen is an optional feature. There is a very easy and convenient for the analysis of a sample of fluid viscosity measurement data saving a CSV file and open with WinCT viscosity.
