The air coupling probe developed by the company is adopted
High-sensitivity piezoelectric ceramic wafers as sensing elements,
The use of air as the medium for ultrasonic transmission can be
Avoid the use of ultrasonic couplings to meet the non-contact type
Scenario detection requirements. The operating frequency range is
20kHz~300kHz, using acoustic impedance matching layer
Design technology and noise shielding technology, with high sensitivity
Degree sensing characteristics.
Air coupled ultrasonic probes can be used without damaging the material
Under the premise of internal defects, delamination or bonding surface quality
Perform effective detection. In addition, due to its non-contact
The features of the air coupled ultrasonic probe also fit online
Detection, can improve detection efficiency and flexibility, reduce
Reduce the preparation time and interface required for traditional contact testing
Quality treatment.
