Weightless scale is a commonly used measuring equipment in the measurement industry. Because of its convenient installation, high measurement accuracy, and convenient use and maintenance, it is widely used. Kehua Heavy Industry is specialized in the production of weightless scales, electronic belt scales, and spiral scales. , professional manufacturer of quantitative feeder, how much do you know about the working principle of weightless scale, Kehua Heavy Industry will introduce it in detail below.

　　The principle of weightless scale and its application The weightless scale was used in continuous measurement of industrial process weighing in the 1990s. Loss-in-weight scales are gradually replacing belt scales, spiral scales, and even accumulative scales. As a new measurement method, they are gradually applied to more and more material handling.

　　The working principle of weightless weighing: take the weighing bucket and the feeding mechanism as the whole scale body, continuously sample the weight signal of the scale body through the instrument, and calculate the change ratio of the weight in unit time as the instantaneous flow rate. Through the filtering technology processing of various software and hardware, the "actual flow, output" adjustment signal area that can be used as the control object is obtained to control the feeder controller such as the frequency converter.
