超声波换能器作为一种实用的检测手段，能实现声波所携带的信息和电能之间转换。它的性能优良，价格低廉，操作方便，易于调试，因此在工农业生产中发挥着重要的作用。但目前换能器驱动电路的发射频率多为40 kHz，本文针对1 MHz的超声波换能器电路进行了设计，主要介绍了它的发射驱动电路和接收驱动电路的设计方案，并对它们的功能进行了详细地说明。最后搭建实验平台，并对电路的输入、输出模块进行了测试。实验结果表明，换能器电路运行良好，可以为超声波高精度测量领域的应用提供参考。As a practical means of detection, ultrasonic transducer can realize the conversion between theinformation carried by sound wave and electric energy.It has the advantages of excellent performance,low cost, convenient operation and debugging, so plays an important role in industrial and agriculturalproduction.However, the transmitting frequency of the driving circuit for most transducer is 40 kHz.Thecircuit of 1 MHz ultrasonic transducer is designed In this paper. It mainly introduces the emissive drivingcircuit and the receiving circuit design and the detailed function of them. Finally, the experimentalplatform is built, and the circuit of input and output were tested. Experiments show that the transducer＇ s...

German universities and scientists have repeatedly set the intermational standard in drive technology. Identification and active compensation of natural frequencies in oscillatory mechanics, status controls with monitoring structures incorporating acceleration sensors, adaptive compensation of measurement system deficiencies, self-adjusting detent torque compensation… everything invented with only a single aim in mind: to continue improv-ing the motion control, dynamics, precision and processing speed of your machines. For the industrial applicabability of this technology scientific publications in proceedings and laboratory test rigs are not enough. These features consequenty need to be converted into cost-efficient and easily manageable products. That 's exactly what we have done.so in future, if you should need more than today ' smarket can offer you, now everything isgoing to be alright.
