Abstract
A strain gauge strip (10a) of the type that can be mechanically applied to a support (1) subject to deformation, is made of Samarium sulphide and provides optimum performance in terms of precision and sensitivity, without being affected by temperature and covering a wide range of deformations that are well suited to commercial application (FIG. 1).
Claims27
A sensitive electric strain gauge element for measuring instruments, comprising one or more strain gauge strips made of semiconductor material, connected to an elastically deformable support and electrically connected to one another to generate an electric signal corresponding to said force, said electric strain gauge further comprising an insulating layer located between the support and the strain gauge strips, wherein said semiconductor material is Samarium sulphide SmSX with X in a range 0.92≦X≦0.98, such that causing a change of material resistance under strain, and providing a substantially constant value of gauge factor for an extremely wide interval of strains, and further providing for a low sensitivity to temperature change.
