SHARED COMBINED TRANSDUCER FOR DETERMINING PHYSICAL AND MECHANICAL PROPERTIES Russian patent published in 1996 - IPC

FIELD: measurement technology. SUBSTANCE: device has casing with prisms having faces running in parallel with longitudinal axis of the transducer, piezoelectric elements mounted on the prism faces and dampers. Each prism face running in parallel to the transducer axis and a face connecting installation face and oscillation input point have the shape of isosceles triangles directed so that the height of the former is in parallel relation to the transducer axis and the basis of the latter plays the role of installation face edge. Hygroscopic inserts are placed on the faces being in parallel relation to the transducer axis. Angle made by acoustic axis of the transducer and distance between ultrasonic oscillation input point and the piezoelectric element along the acoustic axis is calculated using a relation found. EFFECT: enhanced accuracy of measurements. 2 cl, 3 dwg
