Abstract :
Self-calibration methods for long-term monitoring of non-electrical quantities are presented in the paper. There have been discussed the self-calibration methods of measurement channels containing integrated ratiometric output sensors and ratiometric output sensors with strong attenuation (bridge circuits). It has been shown that under certain system solutions this type sensors make measurement results independent from possible changes of the parameters of elements of electronic measuring systems caused by the temporal and thermal instability, and, also, the measurement accuracy improves. In the paper an algorithm is proposed, which enables self-calibration of measurement channels with non-linear conversion functions
