Problems solved by technology
[0005] At present, impedance phase analyzers are commonly used at home and abroad to test the performance of ultrasonic transducers, but there are manual settings and single functions when measuring such instruments, and traditional impedance analyzers can only achieve inherent parameters such as resonance frequency. The measurement cannot meet the actual production demand

The invention discloses a performance tester for a supersonic transducer, and the tester includes a first test state and a second test state. The tester comprises a controller, a first reflection device, a reference transducer and an adjusting device, wherein the controller can be electrically connected to the transducer to be tested to drive the transducer to be tested to emit supersonic waves; in the first test state, the first reflection device reflects the supersonic waves, emitted by the transducer to be tested, back to the transducer to be tested; the reference transducer is electrically connected with the controller, and the in the second test state, the reference transducer receives the supersonic waves, emitted by the transducer to be tested, and is driven by the controller to emit supersonic waves to the transducer to be tested,; and the adjusting device makes adjustment so that the performance tester is switched between the first test state and the second test state. The performance tester for the supersonic transducer can measure different parameters of the transducer to be tested, and also has the advantages including simple structure and convenient use.
Description
technical field [0001] The invention relates to a transducer testing device, in particular to a performance testing device of an ultrasonic transducer. Background technique [0002] Ultrasound will produce many physical, chemical and biological effects when propagating in the medium. At the same time, because of its strong penetrating power, good directionality, large information carrying capacity, and easy to achieve fast and accurate non-destructive testing, it is widely used in industry, agriculture, national defense, It has been widely used in biomedicine and other aspects. [0003] Ultrasonic transducers are energy conversion devices that convert alternating electrical signals into acoustic signals or convert acoustic signals into electrical signals within the ultrasonic frequency range. It is a key component in ultrasonic equipment, and its performance is directly related to the effect and scope of application of ultrasonic technology. Therefore, it has received long...
