Радіовимірювальний сенсор газу на основі транзисторної структури з від'ємним опором

Abstract

This paper considers theoretical methods of analysis of radiomeasuring sensors gas on based of transistor structure with negative resistance. The analysis of the current state of radio sensors, gas concentration. The mathematical model of interaction of optical radiation with gas. The mathematical model of radiomeasuring gas sensor based transistor structure with negative resistance, which helped to get the conversion function and sensitivity, dependence reactive component and negative resistance of power and modes of optical radiation. Adequacy of models (error ±5%). Designed microprocessor unit for environmental monitoring. The fifth section describes recommendations on health and safety at work with this unit. In the sixth section of the calculation of the estimate of production costs and efficiency of the unit investment.
