| dc.description.abstract | Every fluidic and flowable state of matter, including polymers, has their own viscosities and rheological properties. The measurement of viscosity is usually implemented by using a viscometer, such as a rotational Brookfield viscometer. However, the current viscometer that is usually in the lab is not portable, which is limited for its usage at different places. This limitation makes the viscometer very dependent on the power source and reduces its usage efficiency, especially for industries that critically need viscosity data to ensure product quality, such as coating, painting, spraying, and others. The purpose or goal of this study is to develop a portable and handheld viscometer. Before identifying the measurement of viscosity, the design was produced and constructed using SolidWorks software and to ensure that the design was suitable to be produced and fabricated using a three-dimensional (3-D) printer. Open-source Arduino software was used as the device controller to control the motor and sensors, and data acquisition to operate the handheld viscometer. To improve the viscosity reading and sensitivity of viscosity measurement, the spindle shape of the viscometer has been generated in a rectangular blade-shaped form with the use of motor current sensing to measure the voltage from the viscometer using multimeter and converted to a viscosity value. The calibration testing for the handheld viscometer has been tested and compared with the commercial Brookfield viscometer in the laboratory using four different fluid concentrations, which were 100% natural rubber (NR) latex, 80% NR latex + 20% distilled water, 60% NR latex + 40% distilled water and 40% NR latex + 60% distilled water. Besides, the highest speed level of 140 has been used, as it contributed to the most stable data trend and has an almost similar trend of viscosity data from the commercial viscometer. At the end of this evaluation, a portable handheld viscometer was achieved with the help of a rechargeable power supply to supply the energy to run the viscometer, such as a common power bank. In addition, real-time data display was recorded effectively by using this method. The development of this handheld viscometer can enhance the productivity and efficiency of viscosity measurement, especially in real industry. | |
