The provision of design safety is in a great measure determined by the strain parameters in the structures, for the measurement of which gages are used based on different physical principles and with different technical characteristics (measurement range, accuracy, etc.). For the manufacturer of a series of strain gages, their production is a difficult, sometimes  insoluble, technical and economic task. The article presents a conceptual approach to the construction of a family of strain gages based on a unified action principle –  induction, developed by the authors. A functional scheme of an inductive type strain  gage  is  presented.  It  is  shown  that  the  signal  conversion  and  data  processing  modules  are  common  and  can  be unified as functional nodes. The results of development and research of the basic units of the signal conversion module and the data processing module are presented, which allowed designing a unified signal processing module and a unified data processing module. The approach proposed by the authors makes it possible to organize the production of a series of strain gages with specified technical and economic characteristics and a high level of unification, thus ensuring all possible needs of potential customers.
