Speed measurement circuit board

With the RASdelta speed board, you record precise, multi-channel and digital speed measurement data for all transmission, control and auxiliary drive tests. It is the basis for torsional vibration analysis. The data is acquired via magnetic, angular equidistant scanning, an incremental encoder or a laser.
