TENSILE TESTING GAUGES FOR MEASURING STRAINS AND/OR TORQUES

摘要

abbreviated descriptiondevice with strain gaugesthe extent of efforts and / or couples.s. a. "sappel)the invention relates to a device for work and / or sensorcouples are intended, in particular, to the extent of efforts and / or couples ina fluid medium flowing in a conduit, aggressive. the device includesa symmetrical element in the form of a beam (10) extending inside theconduit has a free end (12) to receive the effortthe torque measurement and / or a rigid core (14) intended to be fixed on thethe inner side of a wall (16) of the led, in the region ofthe opening (16a) of the wall, and an intermediate part (11)two longitudinal openings which are formed (24) openon the outside, and at least two type strain gauge sensors(28.30) arranged in two parts of a plan for measuring (22) formedat least a part of the front of the base (14) open to the outside world viathe opening (16a). in this way, a deflection of the free end(12) and 10 middle section (11) of the beam (10), which is caused bythe effort and / or torque to be measured, is converted into a constrainedin compression and tension within substantially the samein the regions where the amplitude of the elementsthe sensors.(see figure 1).
