DETECTION TERMINAL INCLUDING A PIEZOELECTRIC TRANSDUCER SECURED TO A DIAPHRAGM CONNECTED TO AN ABUTMENT STRUCTURE
A detection terminal including a piezoelectric transducer emitting and receiving ultrasound waves via a diaphragm to which it is secured, said diaphragm being arranged opposite an opening of a housing and connected to said housing by connection mechanism. According to the invention, the diaphragm is connected to a rigid structure which enables same, when subjected to pressure, to undergo a contraction limited to the space provided for said purpose, in the opening of the housing, determined by a position of the structure abutting against a surface of the housing opposite the opening.
