Resumen:
In this dissertation are presented of the results of an investigation of the use the
noted paraconsistente logic in the measurement and monitorization of the temperature of a
warm liquid for a heat source. In the noted paraconsitente logic is necessary the
comprehension of how the imprecision and uncertain occur in the measurement process use
the electronic instrumentation, enabling of the relevance and reliance gauge of the results
gathered through paraconsistente logic theory. The fundamental characteristic of the
paraconsistente logic is its ability to represent the handling of inexact information, providing a
method of translating verbal expressions, vacancies, imprecise and qualitative in numeric
values. It is presented a projected system for the measurement and the monitorization of the
temperature of a liquid in which a microtroller is programmed using the noted paraconsistente
logic of two values. In the measurement of the temperature of a liquid was used two pairs or
temperature sensors distributed from way to emphasize the inconsistencies of the measures. In
the monitorization the sings generated by the temperature sensors, after having processed for
a converter A/D are analyzed through an algorithm based on the paraconsistente logic. The
control of heat source is made by an sign originating from the microcontroller after a
conversion D/A. In the experiments it was observed that the results of the temperature
measures presented an accuracy of + 1 °C.
