Paper Abstract

Several theoretical considerations are known dedicated to mathematical modeling of physical phenomena in ionselective membranes. They yield full theory of ions complexation in ionophoric membranes. However all these works give results which are not sufficiently simple and do not explain sufficiently accurate a behavior of the sensors. To provide simultaneously accurate and simple model of the ion sensor we must turn to behavioral description instead of the physical one. In this paper several behavioral approaches to modeling of potentiometric sensors are presented. These models are dedicated to WARMER project. This project is focused on development of automatic testers for environmental water monitoring. The testers consist of a sensor header, A/D conversion and data processor executing a data fusion program. This program realizes a data fusion algorithm based on a calibration-measurement method or a data-fusion method. All these methods make use of the sensor model. The project accepts only models sufficiently accurate and having sufficiently small number of parameters. Among different models an optimal trade-off has been performed.
