MV Ultrasonic transducer matching layer

0

This product can greatly improve the ultrasonic transmittance, reduce the energy loss and improve the sensitivity of the transducer. At the same time, it has high compressive strength and wear resistance, which can effectively protect the piezoelectric crystal and prolong the service life. It is widely used in various ultrasonic transducers.

Product description  

 During the propagation of ultrasonic waves, the mismatch of acoustic impedance at the interface will cause ultrasonic reflections and cause energy loss. This product can greatly increase the transmittance of ultrasonic waves in the ultrasonic transducer, reduce energy loss, and improve the sensitivity of the transducer. At the same time, it has high compressive strength and wear resistance, which can effectively protect piezoelectric crystals and prolong service life. It is widely used in various ultrasonic transducers.
