new transducer types such as dry coupling, air/gas propagation, non-contact, 0° shear wave, very short pulse, very high & very low frequency, high temperature, etc. All attempts have been made to keep such classifications and terminology simple. If you need any assistance, please contact our technical services department
long period is a sign of the reliability of the ultrasonic transducer. In order to receive identical echo signals from the same reflector using several probes of the same type, the technical dimensions must be realised within very fine tolerances. The defined values are therefore determined using special measuring processes
ultrasonic monitoring at high temperatures are presented. Keywords Ultrasonic Sensing, Transducers, Nondestructive Evaluation. 1 Introduction. Ultrasonic sensing techniques have become mature and are widely used in the various fields of engineering and basic science. Actually, many types of conventional ultrasonic
when utilizing Airmar Airducer™ Ultrasonic sensors. Balancing When designing an ultrasonic system, several factors should be considered beyond the transducer itself. These factors include atmospheric conditions, drive and receive electronics and signal processing. This type of target has the disadvantage that the.
Apr 10, 2014 impedance matching layers. The most common types of ultrasonic transducers are capacitive (CMUT) and piezoelectric (PMUT) micro ultrasonic transducers, [5]. Microfabricated transducers have become more and more popular with the advances of microelectronics. As ultrasound propagation is assumed

Available in both single and dual element types. • Requires couplant layer, typically a gel, oil, or paste. • Sometimes used in mechanized or automated testing. Transducers for the Immersion Method. Immersion Transducers. • Acoustically matched for best efficiency in water. • Suitable for parts with irregular geometries.
incidence shear wave or a combination of longitudinal/shear wave transducers can be made. These types of transducers are used in direct contact with the test material and therefore require a highly durable wearplate. Contact Transducers are single element transducers designed for general- purpose contact inspection of
