Temperature represents one of the main interfering effects on piezoelectric pressure measuring sensors, therefore the aim of the thesis was to describe this effect experimentally. The aim of the experiment was to determine the measuring characteristic of a piezoelectric pressure sensor at different temperatures, through which we would deterrmine the coefficient of sensitivity. For determining the static sesitivity of a piezoelectric pressure sensors, we chose a quasi-static method. In the first part of the thesis, we described the theoretical background of the problem, presented our measurement system and its components, and described the measuring procedure. In the second part of the thesis, we presented and discussed the obtained results. with the experimental work, we established, that the coefficient of sensitivity increases by a value of 0.0135 %/°C up to the temperature of 40°C, after which it begins to decrease by a value of -0.0141 %/°C. The results show that the coefficient of sensitivity decreases as we approach the sensor's temperature extremes.
