These metrological systems provide accurate measurement in difficult operating conditions. The most popular among sensors are strain gauges, they are increasingly used in various areas of marine operations and legal proceedings. They are the optimal solution in the field of torque measurement.</p>
<p style="text-align: justify;"><strong>Aim: </strong>The program creates a model of a strain gauge measurement system. Analysis of power output characteristics.</p>
<p style="text-align: justify;"><strong>Methods: </strong>The article describes the construction of a mathematical model of the strain gauge measurement system. The MATLAB SIMULINK library was used for simulation. The work is based on mathematical modeling and is aimed at creating a computer-based strain gauge model. The output characteristics are analyzed. The accuracy of the software model measurement was verified by checking the convergence of the actual and measured values.</p>
<p style="text-align: justify;"><strong>Results:</strong> A software model of the strain gauge force measurement system was created to create a real computer strain gauge measurement system. Output characteristics are obtained.</p>
<p style="text-align: justify;"><strong>Conclusions:</strong></p>
<ul>
<li style="text-align: justify;">A software model of the strain gauge measurement system is proposed;</li>
<li style="text-align: justify;">The output characteristics were studied and the measurement accuracy was checked.</li>
