Предназначено для применения в системах ультразвуковой локации в газовых средах, уровнемерах, системах ультразвуковой сигнализации и управления. Устройство обеспечивает однонаправленное излучение и прием звуковых волн с повышенной эффективностью и стабильностью работы. Устройство содержит соосно расположенные рупорное устройство в виде рупора и предрупорной камеры, акустически изолированного от него электроакустического преобразователя в виде стержневого пьезоблока и согласующей пластины, прикрепленной к его торцу через кольцевую опору, высота предрупорной камеры кратна половине длины волны в газе, диаметр внешнего отверстия рупора и толщина согласующей пластины определяются для второй и третьей моды ее изгибных колебаний.Designed for use in ultrasonic location systems in gas environments, level gauges, ultrasonic signaling and control systems. The device provides unidirectional radiation and reception of sound waves with increased efficiency and stability. The device contains coaxially arranged horn device in the form of a horn and a pre-jamming chamber, an acoustically insulated electroacoustic transducer in the form of a rod piezoblock and a matching plate attached to its end through an annular support, the height of the pre-jamming chamber is a multiple of half the wavelength in the gas, the diameter of the outer opening of the horn and The thickness of the matching plate is determined for the second and third modes of its flexural vibrations.
