Abstract

In a mechanical system, the acting mechanical power is the most important quantity of rotating shaft of machines. There are many methods to measure it such as measuring the torque directly on the rotating shaft and measuring the rotational speed. Also there are many widely used measuring methods and more or less standardized instruments for measuring the rotational speed. A digital hand tachometer was chosen for measuring speed. The torque measurement is more complicate than the speed measurement. It needs a special solution in every occasion. It must be built onto the machine's shaft. This is because the high accuracy, a relatively simple application and the high dynamical behavior, the strain gauge sensor will be chosen for measuring the torque on the rotating shaft. During the design, the shaft was adapted for application of "V shape" strain gauge, to the shaft's end a HBM made slip-ring assembly was connected the rotating shaft with the standing cable and the Spider8 measurement electronics. The HBM CATMAN-Express software was used during the calibration and the tests. The calibration was carried out with 0.5 m long lever and dead weights in 0.5 kg steps up to 4.5 kg.
