There is described the experience with contact transmission and both non-contact and high frequency transmission (with ESA Messtechnik equipment). Also the examples of the practical realization are presented. Keywords — Torque measurement, telemetry, strain gauge measurement, experiment I. INTRODUCTION Torque measurement on rotating shaft by the method of strain gauge measurements, especially with the existing equipment, brings usually two problems: Fig. 1: Hottinger torque sensor - the first problem is the installation of the strain gauge to places giving representative data. These are usually areas without mounting, the groove for tongue area and similar discontinuities – simply such location on the shaft, where the relative deformation is in accordance with the
