In this case, the range of measured effort

is determined by the number and sensitivity of the strain gauges used, as well as

stiffness of the elastic element in their places

location

In the proposed transducer, the expansion of the measurement range is achieved due to the use of an elastic element of variable stiffness and resistance strain gages with an increased sensitivity. At the same time, the less sensitive resistance strain gages are located in the places of the elastic element of higher rigidity. As a result, the range of measured values is extended, and it is possible to use a strain gauge transducer to determine various

Physical values, the limiting values of which are nepei5j, are unknown by the beginning of measurements

Subject invention

Strain gauge transducer containing elastic element in the form of two supporting parts and elastic curvilinear

wafers, painted inside, workers and white-impregnated strain gauges, characterized in that, in order to expand the range of measurements of the force and increase the sensitivity, it

equipped with cantilever seals located on elastic plates, the cross-section of elastic plates being variable in length, and the strain gauges are located on the console racks.
