“…Table 2 compares the accuracies of own measurements with the accuracies obtained in other research centers [ 8 , 13 , 14 , 17 ]. This comparison proves that high-speed camera methods provide much higher accuracies than the traditional methods based on contact or inductive sensors.…”

“…They prove particularly useful in operating conditions, in addition to being reliable and having quick reaction time when the object is introduced into the sensor active zone [ 11 , 12 ]. Another speed measurement method may be based on a measurement system comprising an infrared (IR) transmitter and receiver (infrared sensor) which uses the phenomenon of light absorption [ 13 ]. In this case, black and white markers (discs) are attached to the moving element.…”

In the locations where driving forces are transmitted, the changing tensile forces cause rapid elastic deformations of the belt. The deformation changes the belt speed. Measurement of the belt speed on the friction contact sections is essential to identify elastic slippage. However, the scale of the phenomenon is small, so it is necessary to use precise measuring equipment. The article presents measurements of the linear belt speed with the use of various sensors and measuring devices. A measurement error was determined for each of the presented measurement methods. The method with the highest accuracy was used to identify the elastic slippage on the drive pulley.
