    Rotational Viscometer Applications

    Tips: Types of Viscometers

    The viscometer is an instrument for measuring the viscosity of fluids. There are mainly three categories of viscometers, i.e., capillary viscometer, rotational viscometer and falling ball viscometer according to the operation mode.

    1. Capillary viscometer
    The capillary viscometer is usually a saybolt viscometer and is a common viscometer. Its working principle is as follows. The sample container (including the outflow capillary) is filled with samples to be tested, in a constant temperature bath, and the height of the liquid column is h. Open the cock, the sample starts to flow to the receiver, and time is calculated until the sample liquid level reaches the scale. The larger the sample viscosity, the longer the period. Therefore, this period of time directly reflects the viscosity of the sample.

    2. Rotational viscometer
    The common rotary viscometer is a cone-plate viscometer. It mainly consists of a flat plate and a cone plate. The motor drives the plate to rotate at a constant speed through the variable speed gear, keeps the tested sample between the two plates by capillary action, and drives the cone plate to rotate by the friction between the sample molecules. Under the action of the torsion spring in the torque detector, the cone plate will not rotate after rotating at a certain angle. At this point, the torque applied by the torsion spring is related to the internal molecular friction (i.e., viscosity) of the tested sample: the higher the sample viscosity, the greater the torque. The torque detector is equipped with a variable capacitor whose moving plate rotates with the cone plate, thus changing the capacitance value of itself. The torsional spring torque reflected by this capacitance change is the viscosity of the measured sample, which is shown by the meter.

    3. Vibrating viscometer
    The principle of this viscometer is that an object in a fluid will be hindered by the fluid when it vibrates, and the size of this action is related to the viscosity of the fluid. The commonly used vibrating viscometer has an ultrasonic viscometer with a shrapnel in the detector. When excited by the pulse current, the shrapnel produces mechanical vibration in the ultrasonic range. When the shrapnel is immersed in the sample, the amplitude of the shrapnel is related to the viscosity and density of the sample. Given the density, the viscosity value can be obtained from the amplitude data.

    Do you have a viscometer to measure asphalt ac30?
    Long time without contact with you, but in normal viscometer our competence have a very small price. Do you have a dynamic viscometer to measure asphalt ac30 and PG type?

    ATO Responded
    Unfortunately, no. Our viscometer can not measure asphalt ac30 and PG type.
    It's my favorite viscometer
    After receiving the viscometer, you need to assemble it yourself, which is simple and convenient. There is also an aluminum case to prevent corrosion. After each use, the viscometer is well protected and the measurement results are accurate.
