ULTRASONIC INSPECTION AND MEASURING TRANSDUCER

摘要

FIELD: physics. ^ SUBSTANCE: ultrasonic inspection and measuring transducer which has a piezoelectric transducer acoustically connected to a delay line made in form of mated rotation bodies and a truncated cone whose larger base is joined to the rotation body and the smaller base is the working surface of the ultrasonic transducer is fitted with a delay line mated with the lateral surface and a nozzle which completely covers its conical part, where the said nozzle is made from material with high ultrasound absorption and acoustic resistance which is close to acoustic resistance of the material of the delay line which has the shape of a hollow rotation body with a flat end surface which coincides with the working surface of the inspection and measuring transducer. ^ EFFECT: increased sensitivity of the ultrasonic transducer. ^ 2 cl, 2 dwg
