Ultrasonic Torsional Vibration MethodUsing ultrasonic torsional vibration technology, viscosity is determined by measuring the mechanical impedance of high-frequency ultrasound in a liquid. When the sensor probe generates torsional vibrations at a constant frequency in the liquid, the viscous resistance of the liquid causes changes in vibration amplitude—the higher the viscosity, the more significant the damping effect on the vibration. The device's built-in constant-amplitude circuit monitors real-time changes in the drive current required to maintain vibration and converts them into accurate viscosity values. This indirect measurement method avoids the wear issues associated with traditional mechanical viscometers, improving response speed and measurement stability.。
