Background. The growing need to measure new process parameters requires the creation of new sensors and the expansion of the functionality of existing sensors, and hence their measuring circuits. The purpose of the work is to develop a system of computer-aided design of functional schemes of measuring circuits of sensor that provide measurement of the desired parameters of the production cycle.
Materials and methods. Signal graphs, design methods and object-oriented programming were used in the development of computer-aided design measurement circuits of sensors.
Results and conclusions. Methods of designing of measuring circuits with one-, two - and three-element equivalent circuit of the parametric transducer are considered. The system providing the automated designing of functional schemes of measuring circuits with the set possibilities is developed.
