Description

Изобретение относитс  к области приборостроени .The invention relates to the field of instrumentation.

Известные датчики физически.ч величин, например , температуры, содержащие в качестве чувствительного элемента транзистор и зар дпо-разр дный конденсатор, подключенный к базе транзистора, не обладают достаточной чувствительностью, что снижает точность измерени .The known physical sensors, such as temperature, containing a transistor as a sensitive element and a charge capacitor connected to the base of the transistor, do not have sufficient sensitivity, which reduces the measurement accuracy.

Дл  повыше1;и  точности измерени  в предлагаемом датчике коллектор чувствительного элемента соединен с базой выходного транзистора , его э.миттер - с эмиттером выходного транзистора и резисторол. а база чувствительного элемента соединена с источником питаии  через резистор.For higher1 and measurement accuracy in the proposed sensor, the collector of the sensitive element is connected to the base of the output transistor, its emmitter is connected to the emitter of the output transistor and the resistor. and the base of the sensing element is connected to a power source through a resistor.

Ча чертеже показан описываемый датч1п.Cha drawing shows described dach1n.

К базе транзистора 1, используемого в качестве чувствительного элемента, подключен источник питани  2 через резистор 3 и зар дноразр дный конденсатор 4. Коллектор транзистора / соединен с базой выходного транзистора 5, а его эмиттер - с эмиттером выходного транзистора 5 и резцстором 6.The base of the transistor 1, used as a sensitive element, is connected to the power source 2 through a resistor 3 and a charge capacitor 4. The collector of the transistor / is connected to the base of the output transistor 5, and its emitter is connected to the emitter of the output transistor 5 and the resistor 6.

При изменении температуры транзистора / однозначно мен етс  значение выходного сигнала на транзисторе 5.When the temperature of the transistor changes / the value of the output signal on the transistor 5 unambiguously changes.

Предмет изобретени Subject invention

Датчик физических величин, напрпмер, температуры , содержащий в качестве чувствительного элемента транзистор, зар дно-разр дныи конденсатор, подключенный к базе транзистора , источник питани  и резисторы, отличающийс  тем, что- с повышени  точности измерени , коллектор чувствительного элемента соединен с базой выходного транзистора, его э.миттер - с эмиттером вы.ходного траизистора и резистором, а база чувствительного элемента соединена с источником питани  через резистор.A physical sensor, such as a temperature sensor, containing a transistor as a sensitive element, a charge-discharge capacitor connected to the base of the transistor, a power source and resistors, characterized in that with increasing measurement accuracy, the collector of the sensitive element is connected to the base of the output transistor Its emulator is with the output traisistor emitter and resistor, and the base of the sensitive element is connected to the power source through a resistor.
