| Summary: | Velocity measurement has significant role in several industries that cope with particles to save power consumption and to improve quality of particles. This paper describes the effect of distance on velocity measurement for different shapes of electrodes for example pin, circular, rectangular, and quarter ring electrode. This distance is referred to separation of electrodes. Electrostatic sensors are suitable to measure the velocity of particles due to their inexpensive, simplicity and robust. These shapes of electrodes are modeled by mathematical equations and analyzed by Mathcad software. In addition, velocity is measured in laboratory by different shapes of electrodes in different distances. Cross correlation method is experimentally used to measure the velocity. Increase the distance between electrodes leads to increase the time lag, but velocity remains constant. The results of modeling electrodes and experimental tests are compared with each other and they verify that these electrodes are more reliable in industries in addition to cost- effectiveness and high efficiency. |
