FIELD: physics.
SUBSTANCE: hydroacoustic receiver contains a cylindrical piezoelectric cell whose internal surface is hermetically sealed with air and electrical terminals in which a polyurethane tube is installed with interference on the outer surface of the cylindrical piezoelement, and the end parts of the tube protruding beyond the ends of the cylindrical piezoelement are hermetically sealed by gluing and thermal processing, forming a sealed seam, through which the electrical terminals are tightly passed.
EFFECT: increasing the sensitivity of the receiver, reducing the weight of the receiver pressure, simplifying the technology of its manufacture.
