Abstract
A hydrophone which is automatically inhibited when the immersion depth exceeds a predetermined threshold by action, on the push element ( ) of a switch ( ), of a flexible wall that bends under the action of the outside pressure. The hydrophone comprises a tubular body ( ) with two chambers ( ) separated by a partition ( ). One of the chambers is closed by a flexible diaphragm ( ). Switch ( ) is fixed at the center of one of the chambers. Diaphragm ( ) can push down on and actuate push element ( ) by bending. The body can advantageously consist of two parts that can be screwed onto one another, which allows easier adjustment of the inhibition pressure. A pressure-sensitive reception unit (S) is arranged in the other chamber.
