It deals with the simulated models of active and passive measuring chains with single and differential parametric transducers of non-electrical indexes. The researches of developed simulated model are shown on the test models. A comparative analysis of the results and recommendations on their application are given. The advantage of synthetic models is that, using known optimization techniques, it is possible to choose the best way to solve the differential equations that describe the studied measuring circuit. This allows one to choose the most optimal criteria in terms of developer information-measurement system based on the requirements for speed and the permissible error of measurement.measuring chainparametric transducersimulated modeltest modeltime diagramdeviationизмерительная цепьпараметрический датчикимитационная PSB-модельтестовая модельвременная диаграммапогрешность[Чернецов В.И., Чернецов М.В., Медведева С.Н.
