Abstract
Many resistive sensors are based on the bridge circuit. It enables accurate measurements of the small resistance changes, which is essential for weight, pressure, temperature, and other types of sensors. Achieving the most accurate measurements by bridge circuits-based sensors requires calibration and certification of the measuring channels. This paper presents the design of the simulator of the sensor output voltage, which has the advantage of the improved accuracy of the measuring channels calibration. The equivalent circuit of such sensor is described. The influence of the source voltage errors is considered. The error correction of the bridge circuit-based sensor output is described. The conversion equation of the measuring channel is analyzed.
