  • Measurements on a belt feeder with variable speed and belt tension.
  • PLC controled belt feeder with data monitoring, visualization and processing.
  • Material calibration under operating conditions is the most accurate calibration method.
  • Existing mathematical models for estimating measurement errors do not cover all factors.
  • The speed and tension of the belt must be kept within certain limits during feeding
Continual material feeding represents a process of great importance for process industries. Feeding with belt feeders represents one of the most common methods. Belt feeders are devices that require little space, they are not expensive and, most importantly, they do not interrupt material flow while feeding. Calibration of belt feeders, as well as other measuring devices, is a prerequisite for measuring and achieving a defined level of measurement accuracy. On the other hand, the defined level of measurement accuracy is often difficult to achieve in practice due to the multitude of factors that affect the operation of belt feeders. Existing mathematical models indicate a number of influential factors on measurement accuracy. The paper presents the measurement procedure performed on a belt feeder in laboratory conditions, with variable speeds and belt tensions and the known raised position of the measuring idler. Based on the obtained results, appropriate conclusions were made about the influences on calibration and measurement accuracy
