VT-06 can manage the quality control of industrial products such as heavy oil, paint, and adhesives, as well as the manufacturing processes of food. It can easily measure viscosity over a wide range, such as gear oil used in construction machinery. The measurement involves immersing a rotor in the liquid and rotating it, allowing the viscosity of the liquid to be determined by measuring the viscous resistance (torque) acting on the rotor.

• Vibration and Sound Level Meter

The acoustic power level is used to express the loudness of sound emitted from machinery. The acoustic power level represents the total energy emitted by the sound source. If we compare noise levels and acoustic power levels to earthquakes, the noise level corresponds to the intensity at various locations, while the magnitude corresponds to the acoustic power level. Just as the intensity at different locations is not determined solely by the distance from the epicenter, but also varies due to the propagation path and ground structure, in the case of sound, the noise level varies due to the directionality of the sound source and the distance to the measurement position. Therefore, the acoustic power level is used, and especially in Europe and the United States, it is necessary to specify the acoustic power level of equipment.

• Vibration and Sound Level Meter

To suppress the vibrations of structures and predict fatigue life, it is important to understand the state of vibrations, such as natural frequencies and vibration modes. Until now, numerical analysis methods like the finite element method have been used to predict the state of vibrations. Mode analysis is used as a means to validate the predictions made by the finite element method. Mode analysis involves striking the target structure with a hammer and measuring and recording its vibrational response using a piezoelectric accelerometer, which is then analyzed with a mode analysis system. The recorded time data is converted into frequency data in the form of a transfer function using an FFT analyzer, and the mode analysis software calculates eigenvalues (natural frequencies, natural damping ratios, eigenvectors) through curve fitting, allowing for the visualization of behavior at each frequency through animation.
