Ultrasonic transducer common function problems

- Sep 12, 2018-

With the development of engineering materials science and electronics, ultrasonic transducers have gradually developed and made great contributions to application engineering. Ultrasonic transducers are devices that convert electrical energy and acoustic energy into each other, which determines the performance of ultrasonic instruments. The most basic and important device.

Ultrasonic transducers are actually piezoelectric ceramics whose frequency is the same as their resonant frequency, using the piezoelectric effect of the material to convert electrical energy into mechanical vibration. Under normal circumstances, ultrasonic waves are first generated by an ultrasonic generator, converted into mechanical vibration by an ultrasonic transducer, and ultrasonic waves are generated by an ultrasonic derivation device and an ultrasonic receiving device.


1. The ultrasonic vibrator is damp. You can check the plug connected to the transducer with a megger. Check the insulation resistance value to judge the basic situation. Generally, the insulation resistance is greater than 5 megohms. If the insulation resistance value is not reached, the transducer is generally damp. The whole transducer (excluding the sprayed plastic case) can be placed in the oven for about 3 hours at 100 °C or used to remove moisture to the resistance value. Normal until now.


2, the transducer vibrator is fired, the ceramic material is broken, and it can be combined with the naked eye and the megohmmeter. Generally, as an emergency treatment measure, the individual damaged vibrator can be disconnected without affecting the normal use of other vibrators.


3, vibrator degumming, our transducer is made of cement, screw fastening double guarantee process, under normal circumstances.


4, stainless steel vibrating surface perforation, the general transducer can be used for 10 years at full load, the vibrating surface perforation may occur.
