The Ultrasonic transducer drives the circuit board

Date: 2022-07-29Number: 628


As an electronic component, the Ultrasonic transducer can not work alone. It needs a drive circuit board to give it a drive voltage, to make it work, and if it's receiving a transducer, it needs to take the energy it's receiving and convert it into code. This is its primary function. If the transducer is compared to the human body, then the drive circuit board is equivalent to the human heart, the need for a continuous blood supply to enable people to live a normal life./n/nDrive circuit board generally need to have the following parts:
1. The firing circuit
2. Primary amplifier circuit
3. A second-stage amplifier or a third-stage amplifier circuit
4. Ad sampling something
5. Bandpass filter or other filter circuit
6. Output port, such as: RS485, COM port, there are other output, such as: 4-20mA, CAN bus, profibus and so on.
High requirements, and power protection, overload protection, anti-electromagnetic interference, anti-static protection circuit design.
In addition, the Ultrasonic transducer circuit board not only makes it work normally, but also transcodes data. There are many terminals on the circuit board, there are input terminals, there are output terminals, it needs to receive the power signal into different analog signals, transmitted to different terminals, this is another important role.
