This paper presents several approaches to modelling of potentiometric ion-selective sensors applicable in simulation of ion-sensor systems in environmental water measurements. Hardware-software co-design of systems like these requires models sufficiently simple and accurate for on-line simulation of a chemo-electrical measuring circuit which operates on the base of calibration-measurement or data-fusion methods. Sensor models proposed in this paper are dedicated to a combination of two-ions: one main and one interfering. To provide efficient data fusion for this two-ion case we propose only models limited to four parameters that shall be identified. The proposed models have been characterized by means of lab measurements and a complexity-accuracy trade-off has been discussed. The most accurate and yet moderately complex models are recommended for further application in the sensor-system design.
