Description

(54) ДАТЧИК ТОНОВ КОРОТКОВА(54) SENSOR OF TONES OF KOROTKOV

ни  чувствительности к основным сигналам .nor sensitivity to the main signals.

Исследовани  данного устройства показали значительное повышение точности измерени  давлени  при большом уровне акустических шумов.Studies of this device have shown a significant increase in the accuracy of pressure measurements with a large level of acoustic noise.

Claims (2)

1. Датчик тонов, содержащий корпус, крышку с центральным отверстием, пьеэокарамический элемент, расположенный в корпусе параллельно крышке корпуса, и пелот, закрепленный в центре пьезо-Ю керамического элемента, отличающийс  тем, что, с целью повышени  точности измерени  при большом уровне акусти ческих шумов, пьеэокерамический элемент прикреплен к корпусу своим наружным краем через дисковую шайбу, пелот размещен в центральном отверстии крышки корпуса так, что его торцова  поверхность расположена в одной плоскости с наружной поверхность крышки корпуса.1. A tone sensor, comprising a case, a lid with a central hole, a pie-echoracic element located in the case parallel to the case cover, and a pilot attached to the center of the piezo-Yu ceramic element, characterized in that, in order to improve the measurement accuracy with a large level of acoustic noise, the piezoelectric element is attached to the body with its outer edge through a disk washer, the pilot is placed in the central hole of the housing cover so that its front surface is located in the same plane with the outer surface be the casing cover. 2. Датчик поп.1,отличающ и и с   тем, что диаметр пелота составл ет 1/3 диаметра крышки.2. Sensor pop. 1, distinguished by the fact that the diameter of the pilot is 1/3 of the diameter of the cover.
