Bureau ponit examen ultrasonic sensorem circuitum consilium

Et pluteo imminutiones examen est pignus et sustentacionem electrica potentia ratio normalis operatio momenti momenti. In existentium hendrerit ponit in examination modum, in electromagnoism examen et ultrasonic sensorem fluctus examen sunt duo genera habere superioritatis examen modus. In view of the ultrasonic wave examination law in the sensor sensitivity low flaw, uses low noise amplifier (LNA) and the logarithm detection technology, designed one kind of examination sensitivity high, the available battery power supply bureau has put the examination ultrasonic sensor, and to its performance and so on sensitivity, gain has made the test.
