With the further development of information technology in the chemical, petroleum and hydropower sectors, ultrasonic transducer sensor are widely used in oil level, water level and other liquid level measurement. Utilizing the characteristics of ultrasonic, we know that it can also be made into an u

The characteristic of this system is to use the single-chip microcomputer to control the transmission of ultrasonic waves and the timing of the round-trip time from the transmission of the ultrasonic waves to the receiving.Among them, only the wiring diagram of the front ranging circuit is drawn. T

In recent years, the rapid development of microcomputer technology, artificial intelligence and sensor measurement and control technology has made AGV more intelligent and humanized, which has made AGV move towards the direction of intelligent robots. A fully functional AGV system usually consists o

Ultrasonic sensors use the vibration of the pressure vibrating ceramics on the sensor head to generate high-frequency (inaudible to human ears) sound waves for induction. If the sound waves hit a certain object and are reflected back, the sensor can receive the echo. The ultrasonic sensor can determ

Ultrasonic ranging transducer is mainly used in the field of non-contact measurement. At present, the special ultrasonic system for distance measurement is difficult to be widely used in some small and medium-sized applications due to the high cost. With the development of automobile intelligence, i

The ultrasonic transducer sensor is an ultrasonic pulse signal sent by an ultrasonic probe, which is propagating in the gas, and is reflected after meeting the interface of air and liquid. After receiving the echo signal, the ultrasonic round-trip propagation time is calculated, and the distance or

1. Ultrasonic transducer, what kind of pulse does it need to generate or obtain ultrasound? And, how is the resonance frequency determined?In an piezoelectric ultrasonic transducer, the pulse required is a high-frequency pulse signal, and is determined by its driving frequency. As for the determinat
