ULTRASONIC SENSOR Russian patent published in 2019 - IPC B60R19/48 G01S15/93 G01S7/521 

FIELD: instrument engineering.

SUBSTANCE: ultrasonic sensor is attached to the attachment object and passes through the attachment object. Ultrasonic sensor includes a generator which has a receiving-transmitting surface which transmits or receives an ultrasonic wave, cylindrical elastic element, which surrounds generator outer surface, extending from receiving-transmitting surface in direction along receiving-transmitting surface thickness, and has an inner surface in contact with the outer surface of the generator, a body having a housing with a bottom and in which a generator and a resilient member are located, with the exception of the protruding portion on the side of said receiving-transmitting surface, and annular body, which surrounds protruding section of resilient element and is located in body in contact with front part of attachment object. Between the external surface of the protruding section of the elastic element and the inner surface of the annular body, which faces the outer surface of the protruding section, a gap is provided, as a result of which penetration of water into the body is minimized.

EFFECT: ultrasonic sensor is proposed.
