Description

Prism for transmitter W 201-45 (1/4) inch
A part in the form of a prism of a special shape (usually made of plastic), which is a connecting link between the piezoelectric element of the transducer and the control object and serves to introduce ultrasound into this object at a known angle of refraction.
Used for non-destructive testing of objects. The essence is that the ultrasonic inclined transducer contains an inclined prism, on the inclined surface of which a piezoelectric element is fixed at equal distances from the side faces of the prism, while the thickness of the prism is comparable with the length of the body waves in the prism, ensuring its functioning as a normal wave resonator, and the angle The slope of the prism is selected from the condition for the conversion of the normal wave of the S0 mode to the surface. The technical result is the expansion of the frequency response of the Converter in the low frequency region.
