Detection principle of sound intensity measuring instrument
The ultrasonic intensity (sound power) in liquid acoustic field is one of the most important indicators of ultrasonic systems. It has a direct impact on the cleaning effect of the cleaning machine and the working efficiency of the ultrasonic processing machine. The sound intensity measuring instrument can quickly and conveniently measure the sound field intensity anytime, anywhere, and provide intuitive sound power values.
According to different usage scenarios, ultrasonic power testers can be made into portable and online monitoring types. The sound intensity measuring instrument utilizes the positive piezoelectric properties of piezoelectric ceramics, namely the piezoelectric effect. When we apply a force to piezoelectric ceramics, it can convert the force into an electrical signal. Under the same conditions, the stronger the force, the higher the voltage. If the magnitude of the applied force varies periodically, the piezoelectric ceramic outputs an AC voltage signal of the same frequency. Due to cavitation and other disturbances, the actual voltage waveform is a superposition of a main wave and many secondary waves. Our company's precision ultrasonic frequency (energy) analyzer for sound field can intuitively observe the actual waveform and read out the sound intensity value.
