Development and Evaluation of a Calibration Methodology for Pressure-Resistive Sensors in a Specialized Diagnostic Laboratory

This paper presents the development and evaluation of a calibration methodology for pressure-resistive sensors, implemented within a specialised diagnostic laboratory. The approach utilises algorithmic correction, structured measurement routines, and real-time signal processing to perform sensor calibration exclusively at the software level, without requiring hardware intervention. A custom sensor profiling framework has been designed to enable precise analysis of sensor characteristics, degradation, and long-term behaviour. The calibration algorithm employs mathematical interpolation and dataset synchronisation techniques to enhance accuracy and reduce measurement uncertainty. Experimental validation demonstrated a reduction in average deviation from 18.1% to 1.1%, with an overall tolerance range of just 2.6%. These results confirm the effectiveness of the proposed methodology in improving sensor precision and stability. The system is particularly suited for industrial environments where reliable pressure sensing is essential for safety, efficiency, and predictive maintenance.
