Abstract
Abstract Low cost accurate measurement apparatus are one of the main goal of metrology engineers. One way for decreasing the sensor uncertainties is the calibration process. This study deals with the calibration of a low cost sensor using the corresponding values obtained by reference standards. From the practical point of view, the calibration characteristics should be in a polynomial form. In this study a Genetic Algorithm (GA) is used for the measurement apparatus calibration purpose. As an example, GA based calibration of a differential pressure gauge using standard pressure setting devices is examined. The calibration results, founded using proposed GA, are compared with the results obtained via the classical Least Square Method (LSM). As a result, the recommendations on how to get the better calibration characteristics for the differential pressure gauge are given.
