Тепловий витратомір на основі транзисторної структури з від'ємним опором

Abstract

In article the hybrid integrated circuit of a thermal flowmeter is offered on the basis of transistor structure with negative resistance which realizes the autogenerating device which frequency of generation depends on the charge of gas. Analytical dependences of function of transformation and the equation of sensitivity are received. Theoretical and experimental researches have shown, that sensitivity of the developed flowmeter makes 50 kHz/Liter in one hour .
