The topic of the final qualifying work: Signal processing of electrochemical sensors of nitric oxide.This work is devoted to the study of the technical and metrological characteristics of electrochemical sensors for the determination of nitric oxide manufactured by ANALITHIMAVTOMATIKA LLC. Tasks that were solved in the course of the study:- comparison of characteristics of sensors with imported counterparts;- checking the stability of the sensor output signal;- determination of the linearity of the output signal of the sensor.The work was carried out on the basis of Promekopribor LLC, where a significant part of the factual material was collected: the results of checking the stability and nonlinearity of the output signal of nitric oxide sensors. Calculations were carried out and graphs showing the obtained data were constructed. The analysis was carried out on a special stand using research equipment.As a result of the study, the parameters of nitric oxide sensors were analyzed and methods were proposed to combat the non-linearity of the output signal. |
