Исследована возможность использования шумовых диодов в качестве чувствительных элементов термоанемометров. Экспериментально установлена зависимость среднего значения амплитуды шумовых импульсов от температуры и скорости воздушного потока для моделей диодов ND102L и ND103L. Показано, что при постоянном напряжении смещения, соответствующем напряжению пробоя шумового диода при максимальной температуре из исследуемого диапазона, увеличение скорости охлаждающего воздушного потока приводит к линейному росту амплитуды шумовых импульсов. Определена чувствительность предлагаемого способа, составившая 156,9 мВ×с/м для диода ND102L и 105,9 мВ×с/м для ND103L. Выполнено сравнение амплитудного способа измерения скорости с частотным. Установлено, что предложенный амплитудный способ обеспечивает меньшую погрешность (4,5 % для ND102L и 2,1 % для ND103L), более высокое быстродействие и простоту аппаратной реализации, что делает его перспективным для применения в компактных измерительных устройствах реального времени.

The possibility of using noise diodes as sensing elements of hot-wire anemometers was investigated. The dependence of the average value of the noise pulse amplitude on the temperature and air flow velocity was experimentally established for the ND102L and ND103L diode models. It was shown that, at a constant bias voltage corresponding to the breakdown voltage of the noise diode at the maximum temperature in the studied range, an increase in the cooling air flow velocity leads to a linear increase in the noise pulse amplitude. The sensitivity of the proposed method was determined to be 156.9 mV·s/m for the ND102L diode and 105.9 mV·s/m for the ND103L diode. A comparison of the amplitude method of velocity measurement with the frequency method was performed. It was found that the proposed amplitude method provides a lower error (4.5 % for ND102L and 2.1 % for ND103L), higher speed and simplicity of hardware implementation, which makes it promising for use in compact real-time measuring devices.
