ULTRASONIC TRANSDUCER

摘要

Proposed is an ultrasonic transducer (1) with a housing (5) and a low-thickness cylindrical ceramic oscillator (2) with metal electrodes (7, 8) located on each side, and a plastic adaptive layer (3) disposed between the side of the oscillator (2) facing towards the medium to be irradiated and the membrane (6) formed by the bottom of the housing of the ultrasonic transducer (1). The remaining free space in the housing (5) is occupied by a plastic damping layer (4) designed to damp the oscillator (2). The novelty of the invention resides in the fact that the damping layer (4) is made of high-density silicone elastomer with a high proportion of metal oxide, which can be mechanically mixed and attached in place during the gelling phase.
