Velocity measurement on roll-fed material and piece goods
Velocity measurement is indispensable for process control and optimization in many industrial processes. It is the basis for many other applications such as cut length control, length measurement and velocity difference measurement. In these processes velocity is measured using the laser Doppler technique.
Laser surface velocimeters (LSVs) from Polytec are ideally suited because they can conduct measurements on almost any surface and they are not susceptible to contaminated surfaces. The non-contact measuring technique makes it possible to eliminate any negative influences on accuracy, such as slippage and wear, simultaneously. The product being subjected to the measurement also remains intact. Another benefit of Polytec systems is the flexible interface concept enabling velocity readings via encoder output, serial interfaces, LAN, Profibus and Profinet.
