Description
нени акустических волн в волноводе превышало врем установлени давлени в индуктивном датчике. При этом существует интервал времени, когда пьезоэлектрическнй элемент и индуктивный датчик регистрируют измер емое давление без частотных искажений. Соноставл сигналы датчиков в пределах этого интервала времени, восстанавливают истинную зависимость давлени от времени.the presence of acoustic waves in the waveguide was longer than the pressure setting time in the inductive sensor. In this case, there is a time interval when the piezoelectric element and the inductive sensor record the measured pressure without frequency distortion. Having placed the signals of the sensors within this time interval, they restore the true dependence of pressure on time.
Датчик обеспечивает высокую точность измерени при измерении быстро- и медленномен ющихс давлений. Испытани макета датчика в ударной трубе показали, что его частотный диапазон составл ет О- 200 кГц.The sensor provides high measurement accuracy when measuring fast and slow-moving pressures. Testing of the sensor layout in the shock tube showed that its frequency range is O-200 kHz.
