CAEMAX has developed a system for non-contact power measurement on vehicles, which does not need any additional sensors to detect the angle of rotation. The detection of rotation angle and torque is completely integrated into the robust, watertight housing. Thus, the system is suitable for mobile use.
The power transmitted in real driving is an important parameter to quantify the efficiency of drives. The drive power is calculated from the torque and speed of the shaft.
In driving tests, speed detection on the drive shafts poses a special challenge in particular: Standard optical and electromagnetic methods for measuring the angle of rotation tolerate only slight deviations in the distance between stator head and shaft and are sensitive to dirt and moisture in the environment.
The manufacturer therefore integrates a novel, MEMS-based speed sensor technology into an easily mountable shaft housing which already contains the telemetry electronics as well as the components for the intelligent inductive power supply. From torque and speed, the system calculates the power online and conveniently outputs it as another measured variable.
