Methods for calculating the numerical characteristics of resistance strain gauges for information-measuring and control systems

Abstract

Background. Measuring the degree of deformation of solids is a necessary measure in many fields of science. Such measurements can be performed using sensor equipment containing resistance strain gauges. This type of sensor uses a special type of resistor called a resistance strain gauge. Various methods for incorporating these electronic components into a strain gauge circuit are given. Materials and methods. Using linear equations, numerical characteristics were calculated for different switching options, for example, the sensitivity of the sensor. Results and conclusions. The schemes for including different numbers of active and compensating strain gauges in a measuring bridge are considered. For different types of deformation it is necessary to use suitable switching methods, this must be taken into account when designing information-measuring and control systems.
