Ultrasonic Piezo Microphone Sensors

Ultrasonic microphone    Applications: oilfield detection, Utrasonic pickups etc.    Microphones, also known as wellhead logging microphones, are devices that turn sound into electricity. When the sound passes through the microphone, the microphone can make the current change with the change of the sound wave, so as to detect the distance between the oil in the well and the wellhead.        Code       Frequency(KHz)            Static Capacity (pF)       Bandwidth           (△f)(KHz)  Resonant impedance(Ω) W-IVB…
