Молекулярно-электронный гидрофон с компенсацией статического давления содержит молекулярно-электронный преобразователь, жестко закрепленный внутри герметичного корпуса, заполненного легкосжимаемой жидкостью и разделенного на две камеры жесткой стенкой с капилляром, таким образом, что каждая из камер сообщается с одной из мембран молекулярно-электронного преобразователя, при этом внешняя камера из камер отделена от окружающей среды непроницаемой мембраной, а внутренняя камера отделена от окружающей среды жесткой оболочкой корпуса. При этом камера, отделенная от окружающей среды мягкой мембраной, имеет намного меньший объем, чем другая камера. При этом в качестве легкосжимаемой жидкости используются полиметилсилоксановые или полидиметилсилоксановые жидкости различной вязкости. При этом для стабилизации параметров гидрофона введена отрицательная обратная связь. Технический результат – повышение точности измерений на больших глубинах за счет компенсации внешнего статического давления, что позволит гидрофону иметь одинаковый отклик вне зависимости от глубины. 3 з.п. ф-лы, 6 ил., 1 табл.
